What oil in Pumpe Düse engines... ?
Is anyone here using Rotella T6 in their PD engine ?
I'm leaning towards going with T6 for my CR engine,
and would like to start using it in my PD as well.
I used it once with no problems, but my tuner still thinks I should go for the more expensive 505.01
The secret here is that you ask what oil to use in an
PD ( Pumpe Düse ) engine !
The special VW specifications for PD engines is due to the high pressures in the contact surfaces of the cam and unit injectors.
Increased cam wear is inevitable if lesser oils are used.
the likely consequences are pretty clear...
...You might be able to use Rotella T6 in an CR engine but I wouldn't want to risk the increased cam wear in a PD engine.
Exactly
I add ZDDP additive to mine engines.
Zinc is what protects flat tappet cams.
