This is on my '87 SDL. The check oil light has been coming on/off the last 2 weeks. It's not on every trip but it typically happens on a straight away (not on the corners as some have reported). The light will stay on for maybe 1 minute and it will disappear.

I usually see it come on only once per trip (though I don't drive a lot). The oil level is just fine - I checked. I'm guessing that it's a bad sensor or wire shorting?!
