Within the last 2 weeks: 1996 2.0 Contour, the last of my Schaeffers 5W-30 SL Supreme Blend with a Mobil 1 oil filter. My 2002 F-150 4.6 continues on it's diet of Motorcraft 5W-20 & Motorcraft 820S oil filter. That's all it's ever had since it was new.
This Monday I'm going to change the wife's 2005 4.6 Explorer with Mobil 1 0W-20 & a Mobil 1 oil filter. I think this will be the 3rd run with Mobil 1 0W-20 & Mobil filter. This run is close to 10,000 miles, no make up oil needed. I'm going to do a UOA to see how it held up. Prior to the Mobil 1 0W-20 the Explorer used MC 5W-20 and the MC oil filter every 5,000 miles.
