Ok, in diesel power mag. for trucks some guys are filtering used ATF to 3 microns and running it up to 90% to 10% D2 with no issues reported? I actually met a guy locally that has been running it for 6 years over 100K in his older 2001 powerstroke with no issues.
I am still chicken right now to try it in my truck, injectors/etc are not cheap, even rebuilds.....
Has anyone run this stuff in a TDI? I would be curious if any TDI engines could run on ATF since in Diesel power mag the article say it is very close to D2 in the amount of BTU per gallon it produces?
Please comment on this?
The anti-wear additives that are in ATF and if used in a TDI engine will result severe deposits in the rings, turbo and catalyst that will damage them. Rings can jam up, the turbo will develop deposits that either deform the turbine sufaces causing flow disturbances (Ash formation) or accumulate in the turbine seals leading to a seal blow out and shaft seizure.
The TDI runs significantly hotter than a Power Stroke with a combustion bowl temperature in excess of 4,300F...this is NOT a typo! EGT's at the turbo can exceed 1650F all day long in normal STOCK engines!
ATF is formulated to be used in a TRANSMISSION where there is NO CHANCE for the fluid to get into the motor. These additives used in this application CAN AND WILL CAUSE damage to a motor like a TDI.
Engine oils use a completely different additive package that has to demonstrate it's ability to be consumed by the motor without forming permanent deposits. Newer generation "LOWSAPS" oils (Low Sulfated Ash) have to have unique additives that will not leave any amount of ash in the motor due to the extremely sensitive nature of the engine and its components to ash formation.
To compound this level of stupidity, combine the entrapped wear metals, clutch material on top of the fluids wear additives and you have a recipe to form molten metal in all the places you LEAST want molten metal to form. The wear metals will be vaporized in the combustion bowl and will build up on the piston and rings...and turbine. Once the bowl swirl is disturbed you will be on the verge of a literal melt down of the motor.
Leave the ATF in the transmission, when you flush a transmission, take it to a recycle center for proper disposal.
