Curious if the 9000 5W40 is VW approved for the PD engines (in my case a 2006).
There is a Total Quartz 9000 505.01 5w40 and there is a 9000 5w40 ( 505.00 and 502.00 approved I think ) non-PD derivative. I used the 9000 5w40 in my previous gasoline cars and plan on switching from 15w40 Delo 400 to the 9000 5w40 non PD in my Fiesta 1.6L TDCi diesel.
