My last oil change i went with Harley Syn3.
Simply for the reason that all the Auto Parts stores in town didn't have any 20w50 and getting AMSOIL was next to impossible because their crappy-*** website is USELESS for locating a local dealer... just gonna order a case online next oil change.

I have a guy that live around the corner from me who is an Amsoil dealer. I just ordered a case of 20w50 and two filters from him. This is the first change I have done on the bike so we will see how well this oil will be. Used 4 quarts total for primary and tranny.

Motorcycle specific oil
Im new to owning a Harley, I have had air cooled boxers BMWs for the last 20 years and always ran Mobile1 in them, I never used the motorcycle specific oil as the trans was separate. Do I need to buy the overpriced Motorcycle V twin oil or can I go with good quality synthetic oil? Are there real reasons to run the v twin oil or just dealer manufactured fear. Thanks

There are far better oils out there than Harley oil, Red Line, Lucas, Mobile 1, Kendall, just to name a few, Harley only promotes there own oil, as said early they are not oil specialist, They look to the almighty dollar to do there bidding. I ran they're oil and at 5000miles did my own oil change, they oil was fried, I now change my oil between 2500-3000 miles and I also run Aircraft oil, 25-60 during the summer to help keep the heat down. I have been running Harley since the early 80's, I've had Shovelheads, Flatheads, Sporsters, Evo's, Twincams and now running the M8 motor and I still run a Shovelhead I have had over 30 years. If you want real world data on Oil, have it analyzed yourself.
