In a recent video , I saw where Lubrizol VII’s had a lower percentage of change , drop out , etc. (across all standard testing parameters) versus the SOPUS / Exxon - Mobil joint Infinian venture VII’s (roughly 2% less) . Safe to say we know where Infinian VII’s are utilized (M1 , Pennzoil , Shell & QS oils) , so my question is what current synthetic oil companies : synthetuc oil series utilize Lubrizol VII’s in their synthetic oils as a viscosity modifier ?
