I just read that the 5w-20 oil while it may yield slighty better gas mileage (1%) it shortens the life of the engine!
They said that if you are leasing a car, then go ahead and use 5w-20 but if you are buying and planning on keeping it, then use 5w-30 for longer engine life.
Is this true that 5w-20 actually is not really good for ur engine's longevity and that i should use 5w-30 ??
How does mobil 1's 0w-20 match up? Mobil 1 claims to keep engine life running longer (no wear even after 100,00 miles).
