Oil temp low?
#16
Seems to me if the t-stat was stuck open his water temp would be down.
It's not going to blow your car up tomorrow if your oil doesn't get up to operating temp but it definitely isn't good. When the oil stays cooler like that it doesn't thin out like it's supposed to when it's hot, making it more difficult for the engine to get oil in all the little nooks and crannies that it's supposed to go (like up to the head to lubricate the valve train).

Yep, you're right. I couldn't find any reference to it on ECS or in my Haynes but the Google machine says it's next to the oil cooler.
