Ford F-150 1994 0 miles
The problem with my Ford F 150 1994 300 engine with 6 cilinders is that the oil indicator needle started moving up and down until it drops completely. After turning it off and leaving it for around 20 minutes it works again, but half an hour later it drops again. I changed the oil filter and it worked for a couple of days, but the same problem came back again. Any ideas?
