If your running synthetic your good for up to the 300's in temps. But don't get fooled by the hype, these modern engines run best with the oil temps being high. Trans oil is a different sorry. I have never seen no more than 30* difference between my coolant and oil temps. And this is with turbo's in the Atlanta heat and dyno run with heat soak.
