I go an oil change today. I usually go with Mobil 1 fully synthetic or Valvoline on my 2007 GMC Yukon XL Denali. The guy at the shop said they use BG Oil and recommended it highly. He told me that it is a Mobil 1 base with an additive. Can someone confirm:
a) Is BG Oil (Synthetic 0w30) as good as Mobil 1 or Valvoline?
b) Is the additive they add with it (which was free) a good thing?
