I do use redline heavyduty shockproof in the tranny and redline primary in the primary. Are they better than Amsoil or mobil1? I like to think so but reality is that they are so close that we would never know the difference
The thing I see with Most Riders Is the TIME Element.... I took Me over 25 years of Using "ONE" product that did really well and Lets See, If we can find another person who Tried the OTHER Good products for 25 yrs. ,, Let us here from them here Also!!!!
I find it Hard to "test" from "one brand to another brand" in a few changes "Here and There"... It like changing Socks and washing them in a different detergent then another, another, another,,,, Because over TIME you don't know which "One" Product did What ?..
The opinions are just that, including Mine... Opinions...
My many builds and different bikes. NOT a new bike with few miles on them, then Bragging My Oil Is The Best...... Heck, Like Said in Others Post, and from me,,,,, ANY Modern OIL would OIL for a few thousand miles and Only If you Tear it apart to Measure the internals, Before and After,,,You will just Have to Wait It Out to See...... 25 years ????????
'Nough Said!!
