the one and only time my light came on- my truck was almost outta oil- had the 3k service done, idiot snapped my o-ring on the plug- little by little the oil dripped out- didn't notice till just before the light came on- oil not even registering on the dipstick- THANK YOU MR PARTS MAN WANNA BE MECHANIC!! other than that one time- no light for us-
