Im confused, Ive read as much as I could find, but everybody seems to live in the artic tundra...but Im having a hard time figuring out if I should run 5w-30, 10w-30 or 0w-30 for my particular climate zone. The manufacturer recommends 5w-30, I run it to the full manufactures recommended OCI 7500 miles, the car(03 Suzuki Aerio SX) see WOT daily(with some spark knock and blowby through the PCV caught by a catch can)...it gets very hot here in the summertime and currently we are seeing 40* mornings, maybe high 30s in Feburary. Im due for an oil change in the next week and was curious before making my purchase. BTW the oil Ive used since 5k has been Mobile 1 5w-30.
Any help or recommendations will be appreciated
