TufoilEngine Treatment For Trucks 50 oz.

I have used This product in numerous vehicles of mine. (Gasoline & Diesel) & have noticed the level of engine noise decrease during idling. Even in a '10 Ford Fusion Hybrid with the Atkinson Cycle engine. Many so-called experts say these additives are useless. For the small cost, I'd rather use it to protect my engine, than rely on self-proclaimed experts. I've even used a little in my hard-working Ariens 10-24 SnowBlower that is now 11 years old & still functions very well. The cost is very reasonable per the ounce.

I've been using Tufoil since 1998. Tufoil holds the Guinness World Record for the slickest substance on the planet. The main ingredient in Tufoil is PTFE, the prime element in DuPont's Teflon. Tufoil company discovered a way to break apart PTFE particles into extremely small particles, down around 0.5-1.0 microns. Other PTFE-based products can be hazardous to engines because the particles are very large and have a tendency to build up and block tiny oil passages. Tufoil's PTFE particles are so small that an electron microscope has to be used to see them, and blockage doesn't happen.Tufoil conducted stress tests on around 50 engine additive products with a 4-ball wear test machine. A spinning shaft is pressed against by four static ball bearings. The shaft is coated with the test oil for a certain amount of time, then the shaft's scar is measured. Another test is to see how long the shaft will spin until the additive smokes away. All 50 products tested burned off in under 5 minutes. Tufoil lasted 16 days.So, Tufoil outlasts all other products by an enormous amount of time, it holds the world record for slickest substance, and it will save gas and reduce wear in your engine. Start ups are much easier, and acceleration is quicker because of the faster spin-up of the engine RPMs.I've used Tufoil in my manual gearboxes and differentials. This application is amazing when coupled with synthetic gear oil. It's like taking 500 lbs out of your trunk. Shifter motion becomes super smooth and easy. Everything becomes quiet and silky smooth. Of all the Tufoil applications, gearbox installation is my most favorite because of the drastic and immediate improvement in driveability and gas mileage.Many oil additive companies have been sued for false advertising. Tufoil has never been sued over their product claims. Their product works as advertised, and makes people very happy about their purchase.Tufoil is affordable, especially in comparison to other additives.Tufoil recommends using 8 ounces for an engine treatment, but I prefer 4 ounces. I also use synthetic motor oil. The combination is excellent for start up, smooth idle, quick acceleration, reduced engine wear, and greatly improved gas mileage.Try it for yourself. I know you won't be disappointed.Sometimes Tufoil can be found at Pepboys. They don't always have it in stock.

I haven't noticed a difference in performance as of yet. I have a 2007 Tahoe with 75,000 miles in great running condition. I've just changed my oil and added Tufoil for the second time. My gas mileage is the same as before the treatment. It adds about $10 to the cost of my oil change, so I'm hoping for a positive outcome.

Nice Product!

I would not have believed it, but I can't argue with the proof.- My Toyota 4runner runs smooth again (you know those little 'skips' you get on a 10-yr-old engine? either I fooled myself into believing they're gone, or they're really gone now)- the 4Runner runs about 50 rpm higher than normal- the Harley runs about 100 rpm higher than normalI bought this because my brother suggested it. He experienced the same thing in 4 cars of his. One even ran out of oil, but it did not sieze.Not to mention, some Nam Vet I read about uses it in his Harleys. He rode his bike with this stuff in it from the west coast to the east coast of Australia. If it's good enough for him...I'll continue to put this stuff in all my engines./ Vic

I've used Tufoil for over twenty five years to reduce wear on all my engines. An aviation maintenance instructor turned me on to this stuff which holds the Guinness Record for slipperiest substance known to man. The truck size is the most economical for me as all my engines are on a maintenance dose. Very effective, cheap insurance. You can even use this in non-pressure (splash) lubricated mowers for protection on slopes. Just don't put it in your wet-clutch bike!

I've Tufoil since 1988 in all my vehicles with outstanding results. I do experience better gas mileage, cooler running engines, and less internal friction overall. It is the only oil additive that has been tested by the Canadian and US governments and found to be effective.

Been using Tufoil for years. Have a 97 TC that it has been used on since it was new. Now 170,000 miles later the only items we have to replace was the water pump, belt bearings, battery, and had the transmission serviced. People can not believe that is a 97 and looks and runs as well as it does.Great product.
