Thinking about trying it out with my next oil change... any thoughts? The stuff is hard to find.

 

I'll bite; what is Tufoil?

 

Snake oil Tufoil Engine Oil Treatment
Maybe add a performance chip with that https://landroverforums.com/forum/di...rd-chip-39609/

These products are all a waste of your money IMO, just buy descent oil.

 

Tufoil's ingredient is PTFE, aka Teflon. Same as Slick 50 and some other oil additives.

Why don't you just throw in a can of STP, much cheaper and just as useless? There have been hundreds of these things on the market in the last 30-years, and they keep coming and going, because most ended up doing damage. Remember the first mobil-1 made your car leak like a sieve or slick 50 which was great for babbet bearing but wiped out roller or needle bearings. The one exception to the rule I have found is Lucas products they seem to work well and do not exaggerate what they will do for you. JMO

 

Thanks for the replies... I'll stick with straight high mileage oil.

 

no universal fuel chips either, they are usually just a resistor that you cut inline somewhere that leans out the mixture... sure, leaner mix will increase power, decrease fuel usage...and destroy your engine in a year.
