I just wanted to point out there are 2 oil lights on some vans. There's the red idiot light that tells you when oil pressure is low (for vans without oil pressure gauges), then there's the oil level light (pictured above) that's the yellow one that tells you when your crank case is getting low on oil. If you're having an issue with the red idiot light on the cluster, then that's a whole different sensor. If that's the case, assuming you're running 10w30, my 1st recommendation would be switching to 10w40. Tim
