Re: Oil Change Interval And Oil Filter?
The FSS is suppose to be based upon mileage and time. I believe the mileage is 7,500 miles, but not sure over what period. I am guessing 3 months. I don't worry about the time since we are using synthetic oil there isn't any chemical breakdown to be concerned with as with standard oil. Yes, I do believe it is safe to run 5,000 miles between oil changes since 70% of my travel time is on the Interstate above 70 mph. If I did a lot of city driving with a lot of idling I probably would change it more often since that kind of driving is really hard on a car.
