I had a similar issue in Colorado. Gowesty 2450cc. Automatic. Going over a
pass at 3pm full sun. Buzzer went off. Oil pressure was fine based on my
aftermarket gauge so I think it was the fact that it was the hottest part
of the day and I also just switched to a lighter weight 15w50 synthetic
oil.

Only happened that one time, I did stop immediately and let things cool
down since it was really hot out. Never happened again.
