Oil Change - the Good part and the Bad part

[Water Warrior 2]

A lot of folks will think about the wet clutch and forget about the shearing effect of the gears on the oil itself. This is where a designated moto oil will be of benefit to a rider. Rotella has a good shear characteristic and works well in a bike tranny. Amsoil 10-40- or 20-50 moto oil has a shear factor of a 90 weight gear oil and our bikes love it. But we will be switching to Rotella Synthetic now that I have a source in town. 4 liters of Rotella Syn is $34 + tax, 4 liters of Amsoil is now $80 + tax. Canadian $$$ working for the benefit of oil companies.
Shell has never bothered to get the Rotella certified for bike use but it meets all criteria needed.
