Having problems with your 2002 Chevrolet TrailBlazer ?
Change oil light came on, car had oil change 1000 miles ago, checked levels all good. a few days later check guage light comes on, wife takes to regular shop. Down 2 quarts oil. When that happened oil pressure dropped to bottom. 2 quarts oil in runs fine then check gauge light on again pressure down again. check oil level and it looks fine? @002 Trailblazer has 220,000 miles on it. regular maintenance runs like a champ. Ideas?
Get oil pressure test done and check for codes in PCM
