bruce71198 - don't go with salad oil, your oil should be
Motul 300V 15W50 100% Synthetic – Ester Core Technology (Ester means that the oil temp in higher ranges is reduced by up to 10 degrees Celsius).
The highest temps for racing oils is up to 160 deg. Celsius (some even 180 deg. C.), what you normally shouldn't reach.
My Ninja here in high temperature environment when in move doesn't go above 95 deg. C., when I wait at the signals the temp. can reach app. 105 deg. C. but that all is far away from the highest value.
By the way I have the oil cooler and with the Koso RX2 I can read the oil temperature also and that I measure in the main stream (not at the oil drain plug).
