do not use tufoil in your newly overhauled engine or gearbox

i repeat

do not use tufoil in your newly overhauled engine or gearbox

in fact...

don't even use semi or fully synthetic. Just a normal mineral oil. Using any of the above will result in your engine not breaking in properly.

my concern is that after a major overhaul you need to run in the engine (like when you buy a new car) this is to wear out the bearings until it fits snugly to the crank/conrod..
so i guess if tufoil is very slick.. then the bearings won't wear in properly.
but i think putting it in the gearbox staighaway would be ok.. no new bearings there..

Newly overhauled engines tend to be tight like those straight out of showrooms. With new pistons and rings, it will be a good practice to wait till 10,000 km to use Tufoil so as to let the rings seat in perfectly.

However, we do come across many overhauled engines using Tufoil straightaway for their owners wouldn't want to miss out on Tufoil.

In the case of gearbox, you can use a mixture of 5% Tufoil.

For clutch type LSD, it may be too silppery. If you have to use it to solve a problem, use not more than 5%. We are thinking of 1 to 2 spoonful.

Care and Feeding of the Porsche Clutch

A recent call inquired about severe clutch chatter in a Carrera 2 that had only 30,000 miles on the odometer. It has been my experience during forty years of dealing with things mechanical that the operator is the single most important factor in determining a machines longevity and reliability. Perhaps nowhere is this more apparent than in the clutches and transmissions of our favorite cars, where PIO, or...
