Well, my dad was doing something with my car and decided to check the oil and told me he thinks I've got water in my oil. Never really had any motor troubles from any of our cars, however I do know water in the oil is very bad. Bad enough I recall seeing something like an '01 Cadillac Deville with 85k that had water in the oil going for like $3,000. Doesn't it basically ruin the motor?
