Well had a interesting story, so my cousin called me to day because her impala kept dieing and her LOW OIL light had been, she was driveing it with the light on and when she got to work it sounded like a lawn mower, so my mom fallowed her to walmart and put a quart in it, and it ran fine. So tonight i changed her oil, and it ran fine, nothing in the oil. The car has 200,500 miles and the sticker i had put on said 187,000 miles, that was suppost to be her next oil change, so she drove like 13,000 miles with out an oil change. It has a 3800 S2 It still runs like a champ after the oil change i was shocked, i might put new gaskets on it this weekend, it leaks about every fluid, I know for sho it needs Lim uim valve cover gaskets, but this is just my shocking and weird story!
