so, my check oil level light comes on periodically. when it comes on it stays on for the whole day, but there are times when it doesnt come on for a few days. the last time i experienced a problem like this was in my grand prix and it was because i put thinner oil in the car for winter, so it wasnt reading the oil properly. What does everyone believe it could be? also, is the sensor right on the oil pan? thanks for the help!
