Tufoil Engine Treatment For Trucks (50 oz)

I am a Registered Lubrication Engineer and have been using this product for over 20 years. I read all the testing protocols and results before I ever bought the product the first time. I've used it in everything I've driven since then, and in my place of business, in any equipment (compressors, gear boxes, mixing equipment). My Jeep Grand Cherokee now has 310,000 miles, and is still going strong; it has had Tufoil in it since 30,000. I really like the stuff.

After doing a proper research and a wonderful testimony from my friend, I was satisfied and have used the product for years in all of our personal cars. Right now it is in my 1984 Porsche, in the engine and 8 ozs. in the transmission. It has improved the shifting and of course I am very happy with it. I also use it in many electrical motors and I KNOW IT is working. Best regards to all.

I'm sceptical of additives, but have used Tufoil in many cars over decades.

My Ford probe is approaching 300K. My MGBs have gone many hundreds of thousand miles.

I have been using this product for the last 2 years. Started to add TufOil since I had 10000 miles on my car. Car now has 32000 miles. My commute is about 37 miles/day mixed city/Hwy, with minor long distance travel. Sort distances kill any engine. Tufoil will NOT improve your miles in such short travels. However, it markedly lower engine temperature and sound very smooth. Online reviews vary. After more than two years, this product is excellent . . . and the best price you get it here with the 50 Oz pack.
