Hi guys, I use Valvoline 20 w 50 fully synthetic, every 3000 miles, which in my case is about every 5 weeks. It comes out looking brand new every time, am I changing it too often? I probably am, but my DeLorean deserves a little bit of special treatment! John, VIN #3810. --- In dmcnews@xxxx, "iqmpike" <iqmpike@xxxx> wrote: > Quick question for the group...
