Tufoil Success Stories

Really tired of reading "all-additives-are-snake-oil-BS!" comments in various blogs! Possibly most...definitely not "all!" I began using Tufoil around 1979 — 37 years ago! Wife had gotten a new Subaru with 4-opposed engine — idling engine shook slightly — added Tufoil — twitching immediately disappeared! Have used in everything from old beater pick-ups to a new XR4Ti. Added to a differential. Cured a glitchy manual tranny. Put a couple ounces in my shop oil cans. One word: smoooooth!

I began using Tufoil at 39,500 miles in November 1989. Since then we have enjoyed this 1988 Jeep Cherokee on (6) Jeep Jamborees plus three (3) other off-road events. All the while it served as my business vehicle as I sold long-term life insurance and recruited agents across the mid-south. Many weeks saw over 1000 miles traveled. In 2000 my daughter and her husband-to-be loaded the largest U-Haul trailer they could find which we, using this Cherokee, towed from Nashville to St. Paul, Minnesota, where she attended school for one year; my wife just "knew" we would break down any minute and be stranded but the Tufoil trained engine purred ahead with never a miss and returned us safely to Nashville showing over 400,000 miles on the odometer. The Jeep now has over 565,000 miles and completed another business trip to the mountains of North Carolina during the recent winter weather. Come visit us to ride through beautiful Tennessee back roads and off-road whenever you wish!

We race a Speedway Super Saloon, Chevrolet small block, large displacement engine, developing over 700 horse power, with high torque figures. The previous season when racing had finished, the engine was dismantled and found to have a large amount of wear, so much so it was necessary to rebore the block and regrind the crank.

The engine was reassembled with lower compression pistons, leaving us with a 13.2 ratio. We were still worried that the same thing may happen to the engine this season, we looked at changing the oil brands but felt that the oil we were using should still do the job, and perhaps an additive would be the best way to go. After speaking to other competitors, we decided on TUFOIL.

Our race car using Methanol fuel, gets a small amount of fuel pollution in the oil, so the oil was changed every four meetings and TUFOIL was added. After this season, when dismantled, the engine was found to have no wear, in fact we could have reassembled it and run it again, and that's after thirty meetings of hard racing. Lowering the compression would have helped, but I'm sold on TUFOIL, as this played a major part.

An interesting thing we noticed was the oil temperature, which had always been around 200 degrees, was now around 180 degrees with TUFOIL, telling us straight away that we had less friction.

Approximately fifteen years ago, I had added eight ounces of Tufoil to my car while I was attending an automotive school and the results were quite impressive. The engine was running perfectly before adding Tufoil and afterwards it ran smoother, quieter and had better acceleration. Within twenty minutes of the addition of Tufoil to the engine, the idle speed of the engine increased one hundred RPM. After lowering the idle by restricting fuel to the engine, I realized that significant fuel savings could be realized as well as a reduction in engine wear. I started testing Tufoil on various automobiles and diesel engines in cranes and generator sets. For the most part, all the cars showed improvement in acceleration, engine noise, idle quality, lube and fuel consumption.

Meeting with much skepticism, I started testing on diesel engines that exhibited high oil consumption and excessive crankcase pressure. Generally the feeling was that it couldn't hurt so why not give it a try. The first engine I tested was a Detroit Diesel series 353 engine in a Grove crane that was blowing the dip stick out of the tube and spraying oil everywhere. It was determined that the unit had to come out of service for an overhaul but I convinced my superiors at the time to give Tufoil a try. After changing the oil and filters I added 10% Tufoil to the crankcase oil and ran the engine for twenty minutes. The crane was operated over the weekend and Monday morning we went out to see if there were any changes in the engine. The operator noted that it started much quicker than he could remember. While he ran the engine at full throttle, I pulled the dipstick out and put my face in front of the tube. I then turned and looked at my boss and asked if he could see any oil. He didn't. The crane ran fine for seven more years and was removed and overhauled only after a bad fly wheel necessitated removal of the engine. Since that time, I was approached more frequently to give it a try and time after time we saw impressive results.

The largest Detroit Diesel engine, the 16-149 had similar results delaying an overhaul in a tug boat over one year allowing us to schedule it at a more convenient time. We now have 149 engines running over 30,000 hours with oil consumption meeting OEM specifications for new engines. Presently, RTC operates 15 tugboats and all have Tufoil either in there reduction gears or engines. We presently operate the electronically controlled Detroit Diesel 149 DDEC engines with Tufoil and expect to reach all time record high hours between overhauls.

Most advertised oil additives are full of empty promises and that fuels the skepticism that additives are a waste of money and can be harmful to your engine. I recommend Tufoil wherever you need to get longer engine or equipment life as well as lower fuel consumption. If your still a skeptic, try using Tufoil where you have nothing to loose, you never know. You might be impressed!

Powerflow Ltd were recently commissioned to complete the annual major maintenance at Kourarau 'A' and 'B' hydro stations owned by Wairarapa Electricity. This involved a partial strip down of the 'A' station turbine and bearing maintenance and in 'B' station a shaft and bearing re-alignment.

The Hydro Plant

The plant consists of a 700kW twin jet twin runner Pelton wheel at 'A' station and a 220kW twin jet single runner Pelton wheel at 'B' station. These were installed when the station was built in the early 1920's. Both have large flywheels and direct drive to 3500v alternators. There are four large heavily loaded ring oiler plain white metal bearings to each turbine alternator system ranging in size from 100 to 200mm diameter. The two turbine bearings have their oil reservoirs cooled by copper coils conveying water from the turbine penstock.

As all bearings were being drained, flushed and filled with new oil it was decided to add Industrial Tufoil to all 8 oil reservoirs. It has now been two months since the Tufoil was added and the plants put back online. As most of the bearings are still original from the time of installation and some are getting close to their tolerance limits, it is imperative to keep further wear to a minimum.

Results of Addition of Tufoil

The most dramatic result has been the very significant reduction in bearing temperatures both in the turbine and alternator bearings. Having been familiar with the temperatures prior to the addition of Tufoil at around 30 to 45 degree C, I was extremely surprised when I went back to the plant and found the temperatures had dropped to around 20 to 25 degrees, just barely warm. Our estimates are that we are saving in the order of 2 to 3 kw in bearing friction alone per plant and the subsequent reduction in wear is likely to see the plant perform many more years of faithful service.

Apart from just bearing temperatures there are two characteristics that can indicate a reduction in bearing friction in plants of this size. They are (1) ease with which the plant can be turned over by hand after shutdown and (2) the amount of water required to get the turbine spinning from start-up. In both instances the comments from plant operators have been that the turbines can be turned over more easily by hand and require a much smaller opening of the main needle valves to start the turbines spinning from rest. In the past, 'A' station would require 2 people at least just to move the turbine shaft and now this can be achieved with one person. A similar result has been achieved at 'B' station.

With such a successful result with the turbine and alternator bearings it is now intended that the oil in the hydraulic governors should also be treated with Tufoil and this is anticiped to further reduce maintenance and make significant cost savings. I look forward to being able to report on positive results from the governor treatment and only wish I had taken more specific temperature readings before adding Tufoil so I could have given you exact figures for the temperature reduction.

Just a note to let you know how pleased I am with the use of your product Tufoil. I am in the sewing machine repair and sales of home and commercial units. I find the machines run smoother for a longer period of time using Tufoil. I also use Tufoil in my 2000 and 2005 Toyota Avalon's. My 2000 runs whisper quiet and is silky smooth no matter how hard I push it. I also noticed my 05' shifts into 5th gear at 47 MPH instead of 50 MPH- after adding Tufoil. My gas mileage in the 2000 remains at 22-24 City and 28-30 Highway. On the 05' mileage is 26-28 City and 33-36 Highway. I've checked with the computer more than once to be sure I'm correct. I've used Tufoil for more than fourteen years in all my cars. Thank you for your interest.

It was indeed a pleasure to speak with you today – especially in recalling our conversations of over 13 years ago when I was about to write an article for an organization called the ZR-1 Registry regarding state-of-the-art lubrication. I remember featuring Castrol Syntec as the oil of choice and strongly recommending the use of Tufoil – a product I had used since the mid 1980's. Therefore, here is my testimonial. Although it dates back over nine years – I believe it is extremely relevant to this day.

In June of 1992, I purchased a new 1992 ZR-1 Corvette – which as you may recall featured a GM first – a production dual overhead cam V8 called the LT-5, designed by Lotus Engineering and assembled by Mercury Marine. The engine displaced 5.7 liters and produced 385 BHP – which at the time was considered a real beast. In late 1996, I was determined to have the engine significantly upgraded and by early 1997, with over 48,000 miles, I had the LT-5 removed and shipped to an engine builder in Minnesota. Once there, they tore the motor down in order to replace the pistons, rods, crank, valves and numerous other components necessary to increase the displacement. As it turns out, ordinarily, all these removed components – especially with this mileage – are typically discarded. However, because I had been using Tufoil since the motor had 5,000 miles, the engine builders found that all the removed engine components were in "as good as new" condition – and clearly because of their honesty, accordingly issued me a credit of several thousand dollars. I unquestionably attribute this significant cost savings to Tufoil.

Thank you for a terrific product and I look forward to meeting with you sometime soon so we can compare "inventor" war stories! All the best!

In February 1996, I purchased a 1995 GMC 3500 1 ton Vendura cargo van, with a 6.5 Litre diesel engine, from Georgian Pontiac in Barrie, Ontario. It was brand new.
To this day I still drive this van. I'v ealways used it for my small distribution business. This past week it turned over 790,000 kilometres [490,883 miles]. Yes, Seven Hundred and Ninety Thousand killometres. And the engine has never had any major repairs done to it. The heads have never been removed. Based on what I have been told by former owners of 6.5 Litre diesel engines and service personnel at Georgian Pontiac, the average life span of 6.5s is usually around 300,000 kilometres [186,411 miles] at best.

Well, I have 790,000 kilometres on mine and I am aiming at 1,000,000 kilometres. It still runs so well that I am confident I will see the 1,000,000 kilometres. I have used Tufoil Engine Treatment from the day I did my first oil change on this engine. Every 5,000 kilometres I have changed the oil in my engine and always added an 8 ounce bottle of Tufoil Engine Treatment each time.
And I am truly convinced that Tufoil Engine Treatment has played a major role in reaching such high mileage with my engine.
There is no doubt in my mind that the use of Tufoil Engine Treatment has been a major contributing factor for the long life of my 6.5 diesel.

I also use Tufoil Engine Treatment in my family vehicle, my daughter uses it in her car, and so does my father-in-law in his.

Being specialized in the maintenance, repairs and modifications of approximately sixty Dodge Vipers, I wanted to let you know that we, Premier Chrysler Inc., endorse your product "Tufoil" during the maintenance of our customers' Dodge Vipers. We have been using your product with confidence for the last 8 years.

After using and selling Tufoil for 18 years I felt that I had to write to you both about your excellent product. I'm in my 20th year of running a 3 bay auto repair shop. In my second year I was introduced to Tufoil by my local supplier (already having read about Tufoil before, but was not available in my area I did not hesitate to buy it for my vehicles and to offer it to my customers).

Right from the beginning we observed the changes after about a week. After doing only oil changes and adding Tufoil the engines would idle at a good 200 rpm more than before (with carburetors at that time the idle would have to be readjusted, now a days the car's computer does it automatically for us so we and the rest of the public do not notice this change any more).

We have 90 to 95% of our customers using Tufoil; all satisfied and when they change cars they automatically ask us to put Tufoil in their new or used automobile that they just bought.

Many of our customers' vehicles are over 10 years old and have from 250,000 km to 350,000 km in them.

I see other garages in our neighborhood changing engines regularly compared to us it only happens once every 8 years or so and usually it is a new client's engine which had not been treated with Tufoil.

HERE ARE SOME MORE QUICK TRUE STORIES OVER MY YEARS WITH TUFOIL!

One of our courtesy cars has over 480,000 km on it with the original engine; hardly takes oil between oil changes and the manual transmission (also original) has no bearing noises and now grinding syncromeshes. Another one has over 300,000 km and has the same story, (I'm sure the bodies will let go before).

About 12 years ago we did only an oil change with 8 ounces of Tufoil on a Hyundai Sonata with an automatic choke carburetor. A couple days later the customer phoned me to say that the car would fast idle on cold start at about 3300 rpm instead of 2500 rpm. We verified all and had to bring down the cold fast idle. That's an amazing difference of friction at cold!

We've had 3 vehicles run DRY on oil (BMW's and a PORSCHE 928) with 150,000 to 250,000 km's on them and driving an average of 4 to 8 km. After repairing broken oil pans, etc, the engines never took more oil or would knock at cold or hot.

I have customers telling me they notice their engines run smoother and take less fuel.

THANK YOU FOR YOUR AMAZING PRODUCT WHICH ME AND MY LOYAL CUSTOMERS ARE TRUE BELIEVERS.

I just wanted to say how happy I am to have found you. I havent been able to locate your product for years, but with gas prices as they are now, well I guess I looked a bit harder this time.

The first time I used Tufoil was in my 1972 Dodge 4X4. It got 7 mpg. After putting it in the engine I noticed the rpm went from 700 at idle to 2200. I had to readjust it. The fuel economy went from 7 to 9, then I tried it in the transfer case and differentials, it went from 9 to 13mpg and it just seemed to run much smoother. The truck had 350000 miles on it when I traded it on a new one.

I used it in a number of other vehicles, 1974 Chrysler-went from 14 mpg to 19 mpg and 525,000 miles before the body rusted out. I also had a number of 1982-1990 Dodge 15 pax vans we used for airport transportation. They averaged 12-14 mpg before tufoil, 15-18mpg after. One went at 250,000 miles (the driver kept driving after it blew a radiator hose and ruined the engine after 50 miles) the rest did 500,000+ miles, and one went 860,000 miles and we drove it to the junkyard still running fine.

Not being able to find your product I tried a number of others, I didn't notice any changes in the way the vehicles ran.

I started using Tufoil in 1989 in my 1987 Ford F-150 pickup, when it had 50,000 miles on it. It has the 300 six engine. The same vehicle now has 216,000 miles AND SHOWS NO SIGNS OF STOPPING!! It has the same original piston rings, and never failed an emmissions check.

I have used it in the manual transmission and rear axle and never lost a bearing, they are original! I started usuing it in my 2005 Ford Escape too! 🙂

For someone considering a first time Tufoil purchase: I have been using Tufoil for almost 20 years! Trust the maker, and my word as a user of Tufoil, it works.

We have been using Tufoil with ALL of our vehicles since my dad was 30 (he is now 60) and I'm 26.

1979 Buick LeSabre (still running today, sold to a friend at work; over 195k miles)

1991 Buick Regal (185 k miles+, sold to a friend at work, still running strong, does not burn oil, still at 26 / 17 MPG!)

1999 Chevrolet Venture Van (120k miles and going strong, drove from NC to CA in 3 days, 24.3 / 18 MPG!)

2001 Trans Am WS6 (46k miles and soon to be making 600RWHP, 26 / 17 MPG!)

2005 Malibu LT (65k miles and going strong, 33 / 22 MPG!)

2006 Malibu Maxx LT (71k miles and going strong, 30 / 20 MPG!)

Absolutely NO oil leaks or engine problems from any of the above cars.

I put Tufoil in my 1998 Durango. Highway mileage jumped from 16.6 to 18.5!!! I have owned this car for nearly ten years, and I NEVER got even close to this mileage. I now plan to use Tufoil in all my cars, as well as in my lawn tractor and generator. Thank you for a great product.

My 6 cyl 1994 Jeep Grand Cherokee has just past the 273,000 mile mark. I have been using Tufoil in the engine along with Mobil one synthetic oil since I purchased the Jeep. I religiously change oil and filter every 10,000 miles. I have never had to add oil between oil changes. I used Tufoil in my 1967 Ford Mustang before I purchased my Jeep. It got up to 200,000 miles before it was stolen. My Jeep is still getting 19mpg in city driving and 24 mpg on the highways. I even started using your light oil pen dispenser of Tufoil in my roller skate bearings.

Thank you for a wonderful product. I will let you know when my Jeep turns 300,000 miles.

I thought I would write you regarding your TufOil product. I have been using this product since 1974. I bought a 1976 Olds Cutlass and put over 250k miles on it before selling it to a family member, before I sold the car, the only problem I had had was a blown radiator hose, had to pull the heads and replace the head gaskets. That was the only time the motor had been into other that regular tune-ups and oil changes. The family member I sold the car to put another 100k plus on the car before the timing chain gave up. When we broke the engine down, the bearings and cylinder surfaces were still like new, and when we checked the wear with a micrometer, had less than ..003 in the cylinders, and the bearings looked as good as the new ones we installed. I have a 1985 Ford F150, 300 CID in-line six engine, going on a million miles, this is the original engine and it has been overhauled three time. I use your product in all my vehicles, including the differentials and manual transmissions, even my riding lawn mower. I would recommend this product to anyone. Thanks for a great product.

I began using Tufoil in November, 1989, when my 4WD 1988 Jeep Cherokee with 6 cylinder engine and 5 speed transmission had about 40,000 miles. I bought this vehicle new; for several years it was my only vehicle which I used in my sales work so I drove 1,000 or so miles many weeks; I changed the oil and filter myself using Mobil 1 about every 10,000 miles plus adding the recommended 4 oz. Tufoil each time. Also, I changed the oil filter every 5,000 miles and topped up the oil. In 1996 at 300,000 miles, my technician recommended we replace the oil pan gasket due to leaking; with the oil pan off, he asked other technicians to look up at the underside of the engine and estimate mileage; they estimated 30,000 to 50,000 when it actually had 300,000. The head has never been removed; no internal engine work has been needed.

In 1999 I participated in my first Jeep Jamboree at Land Between the Lakes; I lost a rear bumper; soon I began a few off-road upgrades; later my son and daughter joined me on other Jamborees so we've had fun on a total of 6 so far including the 15th Ouachita in 2004 with my Mom who was 84; this unstoppable Jeep has provided lots of father/son and father/daughter quality time. And, yes, we let ourselves get talked into 3 "red neck mudslinging events" also. Well, I did wear out a pressure washer because I like a clean vehicle.

Ziebart provided rust protection soon after I bought my 1988 Jeep so it has little or no rust. Also, I had it totally repainted the original Colorado Red a few years ago; I say it looks great!

Then in 2001 my daughter decided she wanted to attend a school in Minneapolis, MN. She and her boyfriend found the biggest U-haul trailer in town; they packed it so heavy I used low-range to get out of our up-hill driveway and proceeded from Nashville, TN, to Minneapolis with my wife fearing we would breakdown any mile; the Jeep engine with Tufoil never missed a beat; we got there and returned home safely.

If you attended the Dream Cruise in Detroit during August, 2008, you likely saw my red Jeep with signs on the Yakima rack proclaiming, "600,000" miles. That was a bit of an exaggeration but I can now truly document over 600,000 miles; I even have three log books with record of every expenditure, etc.

Tell Us Your Stories!

When did you start using Tufoil? We love to hear how Tufoil has made a difference for you!

Share Your Story
Hi! I’m Chris Reinauer from Reinauer Transportation. We’re a family-run business, incorporated in 1923. We operate over 50 vessels on the eastern seaboard. We have over 400 employees. Tufoil is kind of an insurance policy. It helps me reduce failures, reduce downtime, run more efficient. Those are my three primary reasons for operating it.
Chris Reinhauer
It was purely selfish. When I was operating maintenance and repair, I got phone calls late at night. Tufoil helped me reduce the phone calls at night. So I got to sleep a little easier. We found some areas where it is hard to quantify the results. Typically, the easiest thing to find a benefit is in a gearbox where it runs under constant load and you get stable load, stable temperatures and you could take readings either on a motor or an engine, either the percent load of the motor or diesel. A lot of the diesels can tell you what percent load is, because they’re electronic.
Chris Reinhauer
You do it before and after running with the Tufoil. Usually, the results are “running cooler.” If you see a 10 degree drop, on a 200° operation, that means a lot to the oil’s health and welfare as well as the equipment in reducing friction (reducing friction / reducing wear). You’re increasing the life of the oil, so all in all, you’re giving yourself more time between oil changes simple because you’re not cooking the oil.
Chris Reinhauer
Most lube oils don’t like to see constant operation over 210°. The primary gear box that we run fleet wide is called an angle drive on a barge pump and they run about 220°. They require a little different oil (turbine oil) that can run hotter, constantly, but running the Tufoil in it, it drops the temperature sometimes 10°, sometimes 15° and sometimes even more than that.
Chris Reinhauer
If you want to try it, maybe you could try it where you already have a problem. If you have a problem and you can’t understand why; it seems like you have to overhaul something a little bit too frequently, try it there. If you’re willing to try new things, try it in your own automobile.
Chris Reinhauer
When you know all these things and feel you have a good baseline, like an experiment, add the Tufoil to your next oil change and then compare. Did Tufoil work for you? Absolutely! The first car I ever added it to, I had nearly a 200rpm increase at idle, which was pretty staggering. That’s one reason I got very interested in it very quickly.
Chris Reinhauer
There’s no other product on the market that could do either. In fact, this product does more than just reduce friction. It’s a good thing.
Chris Reinhauer
It’s been in every car I owned ever since.
Chris Reinhauer
What are your experiences with Tufoil? Lower temperature, less wear and tear and friction, less lubrication breaking down and stuff like that.
Chris Reinhauer
I’ve been using it for about 10 years. I came here and I saw Tufoil here. So it was based on 10 years experience of my own. We use it on the angle drive they use to turn the pumps to discharged the cargo. It works! It works!
Chris Reinhauer
On the Morgan, I had to put Tufoil to one of my reduction gears and it dropped about 5º instantaneously. We were having an overheating problem. After we pinned the boat, changed the flow of water over the keel coolers. The temperature rose in our reduction gears. Put Tufoil in. Dropped 5° right off the bat.
Chris Reinhauer
We’ve been using Tufoil for about 10 to 15 years. Every oil change, we add between 10 to 12%. We change the oil about every 1,000 hours. The oil is always yellow, like new oil. Even the temperature is holding much better from my experience with the Tufoil.
Chris Reinhauer
Actually, we started using Tufoil a few months ago on the reduction gears and we could see already, a drop of a few degrees on the temperature of the oil. Less friction. Tufoil works. There’s no question about that!
Chris Reinhauer
A lot of people have problems with turbos with engines like this. We never have problems with turbos. So, where ever the Tufoil is, it’s working.
