my wrecked 94 did that every single time 30-seconds after car starts, regardless RPM, even idling. of course, every time I checked, oil level was always at proper level despite the 'oil level low' warning. I was kinda just live with it....

oil level sensor (a few hundreds bucks) and oil presure sensor (under $100) are different things with separate warning lights.

J4649 - This also happened to me and it turn out it needed some oil. Add a half a quart and the light should stay off. Just a note these cars require 5.6 qts of oil. So if an oil change was done recently, most cars only take 5 qts and thats probably what was put in.
