to use when temperatures go above 100F for a long time? Mobil1 5w30 or 10w30 are good to temperatures up to 100 F according to user's manual. So can i go with 15w50 for a Celica Gt-s ? Anyone that knows please tell me

i'm not sure exactly about the different weights.. i've been using 5w30 Redline oil, and my car has actually run one notch cooler then before. So maybe check out some redline.

heavier weight will help, but i'd personally focus more on your coolant levels and fuel octane in a warmer climate, provided you stick to a quality synthetic like mobil 1.
