I used Valvoline Synpower 5w-30 and a Motorcraft FL400s filter back when I was commuting to tech school everyday and ran 7,000 -7,500mile OCI's. I bought it with 60,000 miles on it and it had 167,000 on it when my ex totaled it. All I ever had to do to it was replace the alternator once and the timing belt. I've had bigger, more expensive vehicles since then buy I still miss that thing, I beat the heck out of it and it kept coming back for more. They did have a problem with the rear coil springs rusting through where they sit in the bucket, mine had this problem and another guy I work with had that problem on his too, they were still drivable though.
