SQ oil is upon us. People are already starting to find bottles of SQ oil in their local stores. I haven't found any yet. SQ still seems like it will be better than SN and SN+. It will be especially better in this direct injection gasoline engine stuff. SH and SJ were probably about peak for additives. Going from SJ to SL pulled out a lot of additives. SM pulled out even more. SP removed even more and looks like I will go down in history as the worst additives package. SN put some of the additives back, SN+ changed the addtive package around a bit so oil worked better in DI engines. And SQ may just make modern motor oil great again.
