Purveyor of Crooked Facts
New FJRForum rule #11: Your opinion don't count for jack shit!!!My opinion, and that is all that is after using cheap ass GL-4 and GL-5 oil since 1984 without a hint of a problem, is that there is a great deal of truth in there.....and note that "recommended" is quite different than "required".Well that is certainly one opinion. And while there may be some truth in there, it is my opinion that there is quite a shortage of factual information also.It may surprise folks to hear me say that the motivation behind the oblique and changing language regarding oils used by Yamaha and other manufacturers is money. They cut a deal with some oil producing company to package an off the shelf product with the Yamaha name. They then raise the price, make unsubstantiated claims of superior performance and do all they can to lead owners into believing that no other product on earth will work. They stop short of saying their product is required because to do so would mean running afoul of consumer protection laws. Yamaha may have changed their language, but no substantial changes have been made to the FD that would make any commonly available synthetic GL-5 rated gear oil unsuitable. Yamaha and the other makers want you to pay a premium for products you can buy at an Autozone for a fraction of the price. BMW (I own four) wants $22 for a quart of gear oil. I can get a quality brand of the same stuff for $10 less at an auto store or Wally World.
