2007 Expedition OIL WARNING LIGHT ON
 

LED only states OIL WARNING - just had oil changed by Jiffy Lube. Big mistake? Why is LED only giving me an OIL indicator?

First check your oil level before you start the engine again. Then, look underneath to see if they installed the drain plug and filter correctly.

When i get to Expy i will do that. Its my wifes truck. :-)

thanks for the post. I will follow up later today with my findings.
