I'm sure that I've asked this before but I don't remember and can't find info on it. Engine stone cold is showing one notch and maybe almost a half and warm it just hits the top hole of the two.. It's a dark blob at the bottom and has some amber looking oil streaked.. My MM says oil life 30% (about to go to 20) around 2000 miles since last oil change lol.. I'm far off from the sticker that they put on my car.. But anyways should I buy more oil or get a change early or are my levels good?
