255-260 is nothing for oil. Are you running heat on full ventilation during track time?
My issue is altitude. Altitude is much worse for cooling than any ambient temperature. At 58f at 5,000ft it is probably more strenuous than 100f at sea level. I do run heat on full net strength though to help to cool.
