Changing Motor Oil
I am deciding if I should replace my motor oil more often than the recommendation interval.
If 90% of my driving is highway driving, will the motor oil in better shape than if it's city driving ?

Presumably, hwy driving is generally done at normal operating temperatures which allows any accumulated condensation to evaporate and burn itself out of the mix of gas/oil. Oft cold starts and stop/gos may not necessarily generate the heat needed to clean out the luggies. Lubrication is compromised as a result, ergo, more frequent change is needed.
