This oil sample is from my 13' f150 ecoboost . This is the 3rd oil change , previous two were done at 1500 then 6500 miles with Kendal full syn 5w30. This oil change was done with mobil 1 0w40 and changed with 27% left on oil life monitor . I don't tow and mileage is 50/50 town/highway with 3 drag strip passes. My purpose here is to share an oil analysis for a an engine know to be hard on oil . I know it calls for 5w30 , and I'm not worried about the warranty ,so let's not get into all that. It sheared down to a 30 anyway. I like the 0 weight and the extra zddp . ]photobucket[/url]
