I have a 2006 Caravan 3.3L(142k miles) and for about a week I noticed that after I restarted the engine the oil light would we be on. I changed the oil and filter yesterday and it is still happening. I can start the van in the morning and drive it for hours and hours and the light will never come on, if I drive it for more than 10 mins and shut it off then restart the light will stay on. I had high mile Caravans in the past and when there was low oil pressure the light would blink and a bell would ring does this year Caravan act differently?
