(0W-30 in super cold, while 5W-30 in hot weather).
Do engines run hotter in summer?
Automotive air conditioning (AC) will cause the engine to run hotter in the summer because it creates more heat in the engine compartment and there will be more strain on the engine to operate the AC compressor.
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Can a car overheat without oil?
Low oil level: If you still can’t find the cause of overheating, check your oil dipstick. A vehicle that’s low on oil tends to overheat because the oil removes from 75 to 80 percent of the “waste heat” in your engine (in addition to doing its other job of cushioning the moving engine parts).
