Re: Aftermarket oil filter and MPG
Weather, temps, route, etc all drastically change MPG. Unless you drive the same route, at the same speed, same wind, same temps daily, it's tough to compare MPG. I have a Napa Gold (Wix) in mine, and noticed no change over stock. However, I notice a change if the temp drops 20-30 degrees from week to week. Or, I notice a change if I drive more stop-n-go, etc.
