[QUOTE="Monkeypants, post: 109245, member: 2708"] Castrol R40 bean oil made it to stage 2 , 242 lbs. It is quite low in friction at 1.9 total heat from friction. Some conventional oils were as high as 7 total heat. Some synthetics had "not measureable" heat from friction. Most synthetics were in the .5 to 2 range. Three Motul oils were tested, the Lemans 300v synthetic, an oil labelled 5100 and another labelled 7100. The 5100 failed at 195 lbs, Stage 1, the 7100 at 416 lbs, Stage 3. The Lemans 300v failed at 126 lbs. The Lemans had very low heat from friction. Morris oil also did quite well at 196 lbs. This was Morris VTwin 20/50. Golden film wasn't tested. One interesting observation was that a given company might have one or two oils that could resist very high loading and also one or two that failed with extremely light loading. Brand meant nothing. The expensive Royal Purple XPR synthetic that Jim had been using in his fuel injected Norton Commando 880 failed at just over 100 lbs. Royal Purple HPS made 437, nearly at the top of the stage 3 group. [/QUOTE]
