I was a forum regular until a couple of years ago. A new car gets the blood I mean oil flowing . We have ordered a 2015 VW Golf Sportwagon (TDI, manual 6 speed). This will be my first diesel and turbo engine. I know warranty requires a 507.00 rated oil for the VW recommended 10k mile, 1 year OCI but I am trying to search out said oil with the highest VI. I know that Mobi's ESP 5W30 is highly regarded (and 507 approved). It has a VI of 164....similar to many of the 507 oils I have looked at. The 0W30 ESP offering has a VI of 180 but does not have the official 507 rating. Anyone know of 507 oils with a VI in say the...170s?
