I've always used Mobil synthetic 10W30 except for the last oil change. I though I would use 0w30 being that it's colder. Now I was told that being that my car (R model) had 170,000 miles I shouldn't use 0w oil because it won't offer enough protection. Is this true? The temp. never drops below 0F. I've also noticed more "clicking" coming from the engine? Could this be because of the lower W rating (0w30)? So all in all should I be running 0w30 in a turbo car with 170,000 miles or should I be using a 10w30 or 20w50.
Thanx
