I am rumming GC in my Evolution. It normally runs at 70 Deg/C when ambient temperatures are below 80 Deg/F out of boost. I saw 90 Deg/C oil temp driving quickly up (Hwy 74 from Palm Desert) a mountain. At what Maximum oil temp would you be willing to slow down and let the oil cool. I have a 13 row external oil cooler. I expect to see 100 110 Deg/C oil temps in the summer. The oil temp sensor is at the drain plug. Thanks.
