I have always purchased quality oils for my vehicles. Some synthetic, some not, but all had a brand name - except for my transmission and FD oil in my Beemer. For some reason or other which I cannot explain I bought the stuff that bore the name of the store where I was buying it. I figured, "Its GL-5, they don't brew it themselves but buy it from a big-name supplier (I'm guessing), should be good enough."
Well, in changing my transmission oil this spring I had the Brainiac idea to buy something motorcycle specific. It happened to be Belray Gearsaver but I'm sure there are many other fine suppliers. Well...since the change I have enjoyed smoother shifting than I have ever had.
Moral: Pay a little more for a quality product and reap the benefits of the research that went into it.
Now, if someone can help me understand why I was a jackass for so many years, I'd appreciate it.
