I worked at a dealership and a Geo Tracker came in one morning on a hook. I was sent to check it out the repair order saying engine stalled will not restart. Shure enough It was locked up when I checked it.Pulled the dipstick out, it was cover with a substance heavier than tar . asked the customer how often the oil was changed she said never! the service engine light only came on this morning. It had 121,000 miles on it.....
