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.
