According to Silkolene the Pro S 10W50 is good to 120 deg C and club oil analysis over on sxoc.com has shown cars used on track running this oil at temps higher than this without problems. Think Oilman (Opie Oils) then asked Silkolene's head chemist guy about max temp of this oil and they reckoned it was good up to 140 deg C!

Think the plate raises the temperature due to the sensor being housed in metal....

 

Mine hits 120 on the gauge regularly, but I have seen somewhere that the sandwich plate, naturally raises the temp...
