My dad is convinced that he can run his pilot 10 thousand miles on an oil change because the Castrol oil he runs says 10 thousand miles. I think that is bs. What is a realistic number of miles using full synthetic that it can be ran for? 6 thousand miles? 8? Also do you trust the oil life sensor and change it at like 15 percent oil life?
Check the owners manual. Follow advice there. Not on the bottle of oil.
