I've always wanted to ask this question about multi viscosity oils...for example 5w40 oil. I've read where at colder starting temps it's easier because the 5w viscosity and then when it heats up pretty hot you still get protection from the 40w viscosity.
So how exactly does this work ... the principle of it?
In addition to the question above, when an engine seems to run better on multi viscosity oil (aside from additive packages in oil) depending what temperature the engine is at would the oil be at say 36w? Can it do that?
In other words, does it become a certain viscosity depending on temperature? If so, how does it know to do that?
Thanks,
