Just to be clear the engine oil is not to be used in the trans.. States that clearly on the bottle for trans you must use a Gl rated oil which the engine oil is not
Dude I've been selling this oil for years, I have techs on speed dial, You are absolutely incorrect!
It's OK to hate the product, and not to prefer to use it, but please do some research before spewing off incorrect information.
Amsoil states Amsoil 20W - 50 Synthetic MCV, is the oil for my 2009 FLTRSE3 Motor, Primary, and Transmission and I may substitute the tranny oil for another Amsoil product, and I opt not to.
So for those who want to be properly informed, please go to the Amsoil website, enter the year, motorcycle, manufacturer, model and the results will be displayed so then you can choose with oil if an option does exist.
