5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !

Will a little bit of diesel hurt a gas engine?

Which oil is thicker 10w40 or 15w40?

Motor oil grade represents the weight of the oil when cold, as well as at operating temperatures. Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures.5 мая 2019 г.

Whats thicker 10w30 or 15w40?
