I just towed 2400 miles. Went from Phoenix to Flagstaff, AZ, couple big hills, over 100 degrees out and hit 242 degrees on my oil temp. Then went through Vegas to Provo Utah. It was 116 degrees going through Mesquite, NV and my oil temp was around 220.
No issues on the trip. 242 degrees concerned me also, figured high air temp plus the hills was the cause. Thanks for bringing up the thread, glad to see it isn't just me.
