I run 10-40 full synthetic Amsoil & run Amsoil in all my machines from Big Bike to Qauds. You can ask a 100 people & you will prob. Get 100 different answers. I would just find a full synthetic that is easily available by you. This day & age they are all so close & most made by same company, just under different name.

 

Didn't think you were suppose to run synthetic. I run walmart brand 10-40 in my 110s. Change it regularly so why pay a lot for it.

 

Just preference I guess. My mechanics have always told me that synthetic is the way to go in motorcycle engines. I change after every 2hrs & yes it is prob overkill.

 

^i think u nailed it there. Everyone has there opinion on what oil to run, but everyone seems to agree on 10w 40. I feel like the most important thing u can do is change your oil long before you ever NEED to.

 

honda gn4 black bottle , ive run amsoil full synthetic and clutch plates lasted a few rides....

 

When i ran synthetic once I was having slippage issues. Thats when I was told I shouldn't be running it. Most of the time I drop my oil I look at it just to be like that has plenty of life left lol My friends go up north and trail ride for days. The hours they put on there bikes would require like 5 oil changes for me in 2 days

 

From a mechanics point of view and understanding the way these machines work I really swear by petroleum based oil. In other words regular oil- NO synthetic it's not good for the wet clutches, it glazes them bad. Synthetic is not a bad oil at all, really good stuff- just not for wet clutches.

Synthetic is the reason they only lasted a few rides. I ran regular oil on my 2smoker for years with out changing the clutch, and no slippage.

 

as it mixes with the clutch no synthetic's Rotella t is the best bar far...........
