I have a 2008 Hpnds CR-V with about 138k on the odometer. Has had a steady diet of mainly M1 EP 5w-20 and a couple changes of Castrol Syntec with Titanium. I have followed the maintenance minder the whole life and it always comes on between 9,800 and 10,300 miles. Usually add between 1/2 quart and 1 quart in that 10k mile oil change. Think this vehicle would benefit from a high mileage oil or should I just stick with the M1 EP?
