Here is an interesting sms we received on Feb 11, 2010.
" Your tufoil already proven on my Nissan Frontier. Overhauled at 460,000 plus. Minimum damaged and engine quite clean". Hassan Chan. These are exact words and nothing has been changed.
The pertinent point here is this. This is another case of long term usage of Tufoil covering many miles and many years and the product has obviously passed the test. No cracked pistons. cylinder head, oil pump or con-rods. No exceptional wear whatsoever.
And NO SLUDGE!! Sludge is sometimes called the " black death ". High operating temperatures and overextended oil change intervals are the chief reasons. Motor oils become less stable and succumbs to high heat. It is burnt oil like those on barbecue skewers.
Lab tests done at the Tufoil factory showed that with an addition of just 5% Tufoil, engine oil temps run up to 42 % cooler. Horse power gains are only possible within permissible oil temp bands. Too hot, the horses disappear into wastelands.
Is there another product that is proven in this manner under real life and time test?
By the way, the factory in America has a 250,000 mile club dedicated to Tufoil users some 20 years ago. Now, it seems it has morphed into the 500,000 mile club and thus raising the bar.
We look forward to hear from others on a similar experience like this. Cheers!
