^ Yeah, if your oil pressure light comes on, shut the car off and call someone to get a ride to an auto parts store. I remember back when I was really dumb (yesterday at 2PM was when I turned smart
), I did not check the oil as often as I should have. The oil pressure light came on but almost immediately turned off. So I kept driving it for about 20 miles or so. I noticed it would come on when I braked or took a corner. Well, durrrrrrrrrrrrrrrp. Somehow I got home without blowing it up and checked the oil. None on the dipstick. Took 3 quarts to fill it (4.2 quart capacity).
By all means, the engine should have went kaboom. I deserved it. 30,000 miles later and it's doing just fine.
Fix the turbo and never depend on any warning lights. Check your oil often.
