About this part

Product Details

Engine additives are easy to overuse, so the dosing information matters. This is a 32 oz bottle of Tufoil engine treatment additive for use with automotive engine oil service.

Use 8 oz as an initial treatment for a standard 4-5 quart crankcase, then 4 oz at each oil change after that. Tufoil mixes with synthetic and mineral oils used in automotive engines, but should not be used in automatic transmissions. Treat it like any oil additive: follow the listed amount, keep it out of systems where it does not belong, and do the oil and filter service on schedule.

THE BEST

GREAT STUFF! I HAVE BEEN USING IT FOR OVER 20 YEARS IN BOTH CARS AND MOTORCYCLES AND HAVE NEVER HAD AN ENGINE FAILURE. PS I HAVE NEVER OWNED A NEW CAR.

Tufoil

I've been using Tufoil for 18 years and also have never purchased a new car. I find that I get 200,000 miles plus and have had no engine problems and don't burn any oil since using Tufoil. I even use in my lawnmower which I've had for 15 years.

Great engine additive. Been using it for the past 20 years. AutoBarn shipped it quickly!

Chris

TufOil

Great product, Auto Barn shipped quickly, as usual. I've used TuOil for quite some time and I really feel it makes a difference. Sold my '86 Integra a few years ago when it had 240,000 hard driven miles and it was still getting 30+ mpg.

Tufoil

Recently used Tufoil for the first time in my 74 Buick Electra. The 455 engine definitely runs smoother. I like it a lot and plan to put it in my other 3 cars.

Been using Tufoild since the 1990s and it works great in both our Honda and Toyota. Easier starting, smoother engine idling, and even quieter running.
