Just want an opinion.... Car is a 2002 ford focus,101,000 miles. No leaks runs well. I drive 40% freeway, 60% city. I have been running motorcraft 5w20 chankging at 4,000 miles. I have an escort with 200,000 miles been on maxlife all it's life! the engine is so clean inside the valve cover. Alot cleaner than my focus. But anyways what do think about switching the focus to maxlife also and bump up the oci a little? What would be a good oci anyways? I thank you all for the help and I love this site. You all are wonderfull...Thanks
