Diesel_vert, your knowledge of oil is impressive!
I understand the long term importance of using the right oil and the best quality oil. So after reading this thread, the general consensus seems to be that while manual for my MKV GTI states that 502 is ok, 504/507 is better and therefore preferred.
Are all 504/507 oils pretty much the same or suitable? I know that Shell Helix is one of the few on the shelf that seem to be 504/507 approved. In short, is there one brand of oil that you would choose that can be purchased off the shelf, is 504/507 approved and suited to a MKV GTI?
Also, if the dealer was to use 502 during the service (I am not sure what they used) and then I top up between services with 504/507, is this ok?
