hey I was talking to my buddy thats a mechanic and he said that flushing your engine with any sort of kerosine or ATF is a really bad idea. The sludge thats built up in your engine is going to get knocked loose, ending up in your oil pan...well at that point there is a good chance of it clogging up your oil pump. Makes perfect sense to me...besides replacing the oil pump is a PITA. You should try out that Lucas oil stabilizer. But yea thats my 2 cents...for what its worth, your car may be just fine, who knows.
