Description of problem
The gearbox was operating at more than 130°C sump temperature during a 12h endurance race with the current transmission oil. Outside temperature was approximately 17°C.
With Eurol Specialty Racing 75W-140 in the gearbox, during another 12h endurance race, the sump temperature did not exceed 110°C, while the outside temperature had increased to 32°C. This is a direct result of lower friction in the gearbox. Used oil analysis indicated a wear reduction of 55% over a race weekend.
