8,000 miles on the factory fill and still had 31% left on the OLM. Just couldn't stand it any longer and had to change it out. Also had a coupon for $10 off. Total price was $24.57 including tire rotation. Can't beat it with a stick.

I need to do her Cherokee and my Monte some time this weekend. I got lazy and took the Firebird to the local quick change oil place a couple of weeks ago and they repaid me by knocking the window off track and telling me I needed a new serpentine belt (which I replaced a couple of months ago). Someday I'll learn.
