Howdy folks.
I have run full synthetic oils forever, since the late 80s anyway. It sounds like regular oil is a lot better than it used to be, and I am not driving my '97 Subaru Outback much (maybe not even 3K miles a year). I should probably be doing time based oil changes, so there won't be many miles on the oil. It seems like conventional would be fine. Do 5w30 non-synthetics hold up in high heat driving (say 110F+ for a few weeks straight) or should I stick with 10w30?
Thanks, Doug
