What is interesting is that the engine oil is JASO MB. The rule is MA for wet clutch trannies, but not MB. So, it appears that they may be limiting their market segment here to the Hondas that have the engine and trannie oils seperated. Maybe there is an MA oil in the works????

Lots of folks get fooled by the word "RACING" and think they are getting a better oil. It is better for some purposes (but absolutely never in a passenger car!). Redline's "Racing" oil is strainght weight (not multi viscosity) and it contains no detergents. This is done to avoid viscosity index improvers (VII's) that tend to break down under extreme heat, and detergents themselves have no lubricating ability so they only decrease the oils own lubricating ability. This is most likely why your cart mechanic had objections!

A "racing" engine gets warmed up carefully, gets driven hard sure, but maybe even gets a rebuild and certainly gets an oil change before the next weekend....so these are compromises that "racing" oil makes that are no big deal for specialized applications.
