Product Details

Tufoil's claim to fame is measurable. In 1996 and 1997, the Guinness Book of World Records named it the World's Most Efficient Lubricant — a designation backed by testing at the U.S. National Bureau of Standards (now NIST), which recorded a steel-on-steel friction coefficient of 0.029. Fluoramics also cites Canadian government cold-weather testing that showed approximately 10% improvement in cold cranking speed and a 5% fuel savings.

The additive works by suspending PTFE particles in a PAO synthetic base. Fluoramics' founder spent 10 years developing a patented method to keep particles under 1 micron in size and in stable suspension — too small to clog an oil filter, and sized to stay mixed in the oil rather than settling to the pan. Six U.S. patents and five international patents cover the suspension process. An 8 oz bottle is the complete initial treatment for a standard 4- to 5-quart crankcase: pour it through the oil fill cap, no draining required. At subsequent oil changes, only 4 oz is needed.

Compatible with conventional and PAO-based synthetic oils (Groups I–IV) and with 4-cycle gasoline and diesel engines. Not for 2-stroke engines. Fluoramics does not recommend it for engines with wet clutches, where reduced friction can cause clutch slip. For engines running PAG/glycol-based Group V synthetics, Fluoramics recommends a simple compatibility check before mixing.

Tuff oil

Iv'e used this product many times and enjoy the ease of starting it provides in the winter months. With 230,000 on a 1990 toyota 4x4 with a high poser 22RE, everything helps. Auto Barn had the best price around.

Tufoil Engine Treatment

I have used this treatment in my 2001 Ford Explorer Sport and went 368,000 miles which they say is unheard for the 4.0 liter 6 cylinder Ford engine. Along with Royal Purple motor oil, you will get your moneys worth from your vehicle. That's like 22 years of mileage in 10. So I bought another Ford 2002 Expl. Sprt and using Tufoil again. This is the best engine oil treatment out there. I add it every other oil change. Which with synthetic oil is 12,000 miles. So every 24,000 miles I use it. Works wonders. And the price from Auto Barn is another good thing.

Tuff Oil

So far so good. Noticed a smoother running, more powerful running engine. Fuel mileage increased slightly. I will buy agian. 1979 Volvo 242 DL - 330,000 miles.

Bob

Tufoil

2006 Ford Crown Victoria 89000 miles - went from 18.8mpg to 19.2 in two tanks of gas. Runs a litttle smoother. Good product, worth it if you have an older car in decent shape, with high miles. It won't solve all your problems or make your car run like new, but it will help.

Is it Tuff enough?? You Bet... Save your engine and feel the difference. Easy ordering and shipping...

TufOil

I've been using TufOil for more than 20 years in cars, trucks, lawn mowers and snow blowers. The 2 things I noticed most were that all the engines lasted longer (particularly the small 1s) & started easier, in cars & trucks the mileage improved.

Super protector for engines

Unbeliveable product I have been using this product for over twenty years . Saved my engine in the the early eighties . When rubber oil pan plug became soft and came out of engine. This product was put in at prior oil change . Saved my engine the car had zero oil pressure and still ran . Will always buy this product . Note in guiness book of world r�cords it's the best.

Have been using in all motors for over 30 yrs

Guys are skeptical and picky about oils and lubricant additives. 30 yrs in every motor. Cars, atvs, lawn mower, boats, wood splitter( 13 yrs, 60 cords +) ... u name it. 100 % confidence. It saved a car motor and boat when Intakes plugged. Engines should have seized. Old motors start right up Just purchased my first diesel truck and will be using it there. Don't hesitate. Just start with a small 4 stroke motor. I don't run anything without it.
