[QUOTE="Jaybird, post: 1168477, member: 22283"] I'm curious if they mentioned how the TBN managed to rise after the bike has been run over 6 hours and sat for the winter? The running will deplete the base some, and just sitting will allow oxidation, and the resulting acids, to lower that number even further. As far as the viscosity testing goes, MX4T pours out in the middle of the 40wt rating. Your oil has sheared down to just above 30wt. (30wt oil @ 100c < / = 12.49) Most ISO grade oils use the 40c testing for viscosity, and you can use the following formula to determine the ISO grade SUS of the oil: [B]SUS @ 100 deg F/5=cSt @ 40 deg C.
