start with oil level and move on from there. Could be a number of things. Any other hints like rough running bucking when cold? Anything that maybe seems unrelated, but might help us pin it down?

i was told by auto zone. That if you don't tighten the gas cap. it could cause the light to come on. He was right. I always make sure it is on tight, my light quit coming on
