Now that I have a car that has no leaks (knock on wood), I had decided to follow the manual for fluid specifications. However, there are a few issues bothering me.
The book calls for 10W30 motor oil. Since I live in Colorado, and it could get pretty cold in the winter, should I still put 10W30 for the winter, or should I get something thinner?
Gasoline. Because of turbocharging, the car requires premium (91RON minimum). I have discovered that gas in Colorado is different from gas in WV. In WV we had 87, 89, 93RON. Here in Colorado the only options are 85 (not E85 though), 87 and 91RON. Why the difference?
I always fill up with 91, but should I maybe pay more and put octane booster every time?
