try checking the ground connection on your - battery post.. i have seen a similar problem where the oil temps go up for some reason, but when you tighten down the ground connections, the problem goes away..

def a ground problem. They are prolly on the same ground circuit. Clean the grounds directly off the gauges, as well as the battery terminals, and all other grounds in the engine bay.

hah... shhh... now its running very coooooool... but still everytime i turn the head lights on it'll jump +16º, have hit over 290º with headlights on, turn headlights off ~2 min later temps drops to ~210º...

now, last weekend driving to BugJam, doing 80mph i was seeing ~168º for oil most of the times and it would go down to 160º sometimes...
coolant temps were around 160º as well...
