I just changed my oil on my 2003 636zx and the same thing happened to me so I loosened up the oil filter just as soon as I seen oil I tightend it back up oil light went off. Man u talk about a scare next time ill just fill up my oil filter before I put it on.I filled the filter before I screwed it on and everything. (engine off) I tried unscrewing it a little and putting it back on but that didn't help. Should I do the same with the engine on?
Oil light wasn't on before oil change FYI
