Re: What oil and oil filter are you high mileage guys using

Mobil 1 5w-30 (no high mileage) and Wix filters in everything I own; new, old, import, and domestic!

I change my oil when the computer says oil life is about 30% (3-4k miles) and after I run 1/3 of a can of sea-foam in the oil for about 50 miles for a good cleaning. I consume about 1/2 a quart of oil every oil change.
