new poster so be gentle... purchased 2017 VW Beetle; manual says for gasoline engines (there are no 2017 diesel Beetles) oil specs are 502.00, 503.00 and 504.00, and, VW recommends Castrol. Couldn't find any Castrol 504.00 locally, so called Castrol corporate. They told me VW 504.00 is for diesel only and the VW owner's manual is wrong. Called VW HQ (cust svc) - they said manual is correct, 504.00 is for use in my gasoline engine 2017 Beetle. Called my dealership. Was told NONE of the manual-listed specs was for gasoline engines, that they ALL were for diesel (admittedly, this sounded like a "call taker' who just was parroting back what someone from service area reportedly told her). Now, someone is wrong here. Either my VW manual is right and 504.00 is ok for my 2017 Beetle, or it's not. I sent an email to the dealer service manager explaining the inconsistencies, so we'll see what he says. Anyone know anything about this? I thought I went to the 2 real "sources of truth" - the oil manufacturer, VW corporate, and my dealership service dept - but getting different answers.
