Ok, I've seriously tried to look through lots of oil recommendations. I find lots of statements from folks about whats good and bad but very little in the way of actual lab reports or other data to back it up.
Is there some place that collects lab reports for various oils for Volkswagen cars?
Is there an FAQ or summation of the available lab reports to indicate what oils are good in what circumstances.
In my case, I'm looking for the best oil to get 10k oil change interval with a 2017 Golf (MK7) Wolfsburg.
I know 502 is the requirement.
I'm trying to find comparative information regarding, Mobil 1 0w-40, Castrol Edge 5w-30 or 0w-40, any of many LiquiMoly 5w-30 or 5w-40 oils.
