Definitely, lots of good synthetics out there. Mobil 1, Redline, Amsoil to name a few.

 

I run Amsoil works well cost more to run, runs cooler, shifts better, more mileage between oil changes.

 

I think most people will recommend doing that. Myself included.

go ahead and switch to a good synthetic if you buy onsale price is not bad when you consider longer change intervals.

i use :
Mobile-1 20w50 V-twin in the crankcase.
Mobile-1 T10w40 V-twin for wet clutchs in the primary.
Nobile-1 75w140 gearlube in the tranny.

do a search there are hundreds of posts on oil very intertaining

 

Cool thanks, I'd rather here some input from guys that are actually using it rather then some sales speal

 

Use that.

 

Well , you asked....
I personally like
Royal Purple 20w50 for the engine.
Redline Heavy Shockproof in the trans.
Harley primary oil in the primary.
I have tried a few different combinations , and these seem to run the quietest in my bike.
I used to be an Amsoil enthusiast , but the engine seemed a bit more ticky and more clatter with Amsoil.
I may try Redline 20w50 next in the engine , but the Royal Purple is the quietest so far.
They're all good , just personal preference.

Synthetic all the way for me too!
