Strange "Oil Change Required" Behavior
I've done a forum search for this issue but couldn't find anyone else mention it, so I thought I'd run it by all of you.
I've seen the "oil change required" indicator before. For me, it usually comes on at around 5,000 miles (although I know it's not distance-based, but rather takes other factors into account). If I remember it right, the message stays lit for a few seconds, and the check engine light comes on. No problem.
In this case, I had driven about 300 miles on a highway, took a break for about 20 minutes, and when I started the car again, the message came up, and has been coming up ever since then. I had only driven about 1,500 miles since my last oil change.
However, it's a bit strange, which is why I wanted to run it by all of you. It seems as if the message appears after about three to five seconds of starting the car, which is longer than I remember it taking. More importantly, it disappears very quickly, either before or right around the time that the warning tone stops. The check engine light never illuminates during this whole process.
I've read over the procedure for resetting this indicator, which I'm thinking about trying. Two questions: is this a cause for concern about anything? And am I somehow mis-remembering how the usual oil change indicator worked, and this is how it's always been?
Thanks for the help!
