What happens if I use 15w40 instead of 5w30?

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 !

Can I use 15w40 oil in my petrol car?

15w40 is typically used in diesel engines. … There are other additives to address issues particular to diesel engines but aren’t detrimental to gasoline-powered engines if the oil is used in them.

SAE 10W-40 semi-synthetic engine oil for diesel and petrol engines. maxxpower premium engine Oil SAE 10W-40 is a semi-synthetic engine oil for all vehicles with petrol and diesel engines with and without turbochargers. Due to the high viscosity range the oil is ideal for all-season use.

Which oil is thicker 5w30 or 15w40?

E.g. 5W-40 is thinner when cold than 10W-40, but 5W-30 and 5W-40 are both within the 5W range when cold. The number after the – specifies that the oil’s viscosity when hot falls into a specific range. So 5W-40 and 15W-40 both fall within the 40 range when hot, but 5W-40 is thicker than 5W-30 when hot.
