On several occasions I've posted the links to Mobil's sheet promoting EHC45 and 65 base stocks. The take is that if a blender uses these Group II base stocks, they won't have to use Group III. If, not, then (about 50%) Group III is necessary for 5w20 and 5w30 SN/SN+ certification. So my question is: What blenders use these Exxon Mobil base stocks? and Are group II, EHC base stocks as good as other refiner's Group III base stocks? I've done some Googling on this and can find no one stating that they use the EHC's. Since most people would think Group III is superior, it's probably not the kind of thing a vendor would promote. I can post the link to EHC base stocks, but I've done that about four times in the last few months. If anyone wants to see it, I can repost again.
