Not really an issue, but something I discovered that I thought was odd. So I change the oil all the time on our fleet cars, and am very familiar with what size wrenches I need. The 2002 impalas take a 15mm, and the 2006/7 impalas take a 13mm. Well, my coworker bought an 08LS and had me change the oil, damn thing is a 15mm! Why on earth would GM have changed it midstream?

Replacement maybe? Though the replacement GM plugs I've had to pick up over the years have generally been 13mm now, even for my older cars with 15mm plugs.

When I went to a parts store for a new oil drain plug they have me 2 options and said the thread pitch was different but without a second vehicle to take my old one in the compare I have just been using vice grips to get it out lol

I guess it's possible it was replaced, but the damn car only has 30k on it. Weird...
