Seeking advice from oil gurus, especially SOPUS fans.
I've got PP 5w-20 in my Saturn, which specs 5w-30. I went with thinner oil for winter and for once I guessed right---but I don't want to leave 20-weight in this engine much longer with hot weather coming, so I plan to change it out in May, even though it will only be about 5 months/4K miles.
I've run M-1 HM with good results, but I am happy with PP and plan to stick with SOPUS, barring an insane deal. So, how different is QSUD from PP? I've researched this and seen conflicting info. AAP has a good deal on QSUD for a few more days, which tempts me. But how much if anything do you lose going from PP to QSUD? Same company---kinda sorta.
Anyone know the latest on this? Thanks.
