What type of oil do you use and why?

I am thinking about changing the oil I use, I currently use the Syn 3.

I would like to know what others are using and why.

 

I went with synthetic at my first (1,000 mile) service and I wasn't quite sure that the bike ran as quiet as it used to so at 2,500 miles I did an oil change back to fossil. Not noticing any difference, at 5,000 miles I did the service changing back to synthetic. Fast forward to my 10,000 service, the dealer used the syn3 in all 3 holes. DEFINATELY NOTICABLE difference in the way the bike sounds and feels! It's much quieter than it has ever been (no ticking) and the clutch is much crisper than it had been. In the future I will be requesting the syn3.

 

After reading many threads in the OIL section of this forum,
i currently have Mobile 1 in the engine, royal purple in the tranny, and Trick Shift syn ATF in the primary

 

You should have offered Mobil 1 V Twin as an option.........that's what I use, 20w-50 weight

 

+1 on mobile 1.

 

Amsoil synt

 

Thanks for the input. This is why I offered the "Other" option, I did not even think about Mobil 1 as an option.

 

well my indy shop did a test

they have a chopper with a 130 in something in there that always ran hot

they tried all the different oils in it, syns and normal


when they switched it over to royal purple the temps dropped an extreme amount of degrees on the cylinder heads, so that was it - I will try to dig up my post about it

but operating temps are operating temps and this thing dropped a bunch with the RP in it.

 

ok so it was a chopper with a 113 motor in it and the oil temps dropped 20 degrees (at operating temp) on the bike


here's a link to the post last year

Using syn3 in all three holes. Everything is running quieter, no issues at all.

Most of the other brands are not as accessible when on a trip. Pull into any HD Dealer and they have it on their shelf.
