Let us put the warranty problem aside for the moment.
From what I understand, VW507 oil is required mainly for extended drain intervals.
Does that mean you can use any synthetic oil (PP, Syn, M1 (not the ESP version),...) which are not VW507 certified in a VW507 oil required engine, as long as it is not for extended drains (between 5 to 8 Kmiles)?
Are there any other problems you can have by not using the correct oil, even on shorter OCIs?
To be more precised, I am talking about 5W30 version of these oils.
Thanks in advance,
