I'm a courier driving a 2015 Mazda 3 doing 250 highway miles per day, approximately 6,500 per month and presently have 225000 miles on it. I use Castrol Edge synthetic motor oil as per manufacturer and am considering going with the Castrol Edge extended synthetic to cut down on the number of oil changes I do per year. The car is running great I do not burn any oil, so my questions are,
1. Would you recommend I make the switch now given the number of miles I have on the car
2. If so would a different type of oil filter be required.
