Are you supposed to use 5w30 in warmer weather, and 10w30 in colder, or is it the other way around?
 
What kind of car do you have? You're not suppossed to use 5W-30 at all if it's turbo.
 
Your suppose to use 10W-30 is the summer and 5W-30 is a winter oil.

10W-30 when the temperature is not lower than -20C(-10F) but higher than 35C(100F)

oh dont worry, its a just a POS 88 accord. Well, its kind of a POS, but it runs well, works good for my cheap ass. And it never gets higher than 100º.. well it does, but not too often.
