It's so sad that we still have people, after all these decades, who believe any kind of BS about voiding warrantees because you didn't use the Harley brand maintenance items like oils. The federal warranty law that outlawed that practice has been in existence since 1975, and if my feeble old mind is still able to do basic math, I believe that is right about 40 years now. Ignorance and BS artists are so pervasive in our society because way too many people are too lazy to find the facts for themselves. There might have been an excuse back when looking things up required a trip to a library, but there is absolutely no excuse these days. Of course, you still have to be smart enough to seek answers where you have the best chance of getting facts and not just more BS. Opinions are not facts, and it would be so very nice if people would not state BS opinions as fact. But then that would take all the fun out of it for the BS artists, wouldn't it.

Oh, and btw, taking the word of some supposed Harley mechanic that SYN3 is not a synthetic and it's made by Mobil 1, when both claims are easily refuted with 30 seconds of research or a glance at the bottle, is sad. If you don't want to take the time to verify the BS you've been fed, at least don't pass it along to anyone else.
Oh, btw #2, Twolanerider is not the target of my little rant. His BS has a purpose, which is to highlight the absurdity of the other BS thrown around in this thread.
