Ok less thought of question. What kinds grades of oil does everyone run in their rigs??
10W40 for warmer nine months, 10W30 during Alaska winters.
10W40 makes engine last longer but results in a slight decrease in gas mileage. (EPA/government regulations and slightly better mileage is why manufacturers specify 10W30.) 10W30 because 10W40 makes it harder to start the engine in severely subzero temperatures.
I change oil and filter every three months or 3,000 miles, whichever comes first. Will skip a change if vehicle has been sitting idle and oil was changed after the last use.
Because I change so often, I use whatever is cheapest or convenient.
