7 Qts of Pennzoil Plat Wix Filter 90,000 Miles on Car 9,660 Miles on this oil sample I drive moderately steady with the occasional hard acceleration. Mostly highway miles in the New York - New Jersey Metro area. I have been using Pennzoil Plat 5w-20 and Wix Filters for the last 9 oil changes. I really like PP and wix. I think it's a good combo.
