Hi all...I've got a question, I want to change all the fluids in my 08 street glide and I want to use mobile 1 full synthetic v twin 20-50. My question is can I run that oil in the engine, primary, and the transmittion?? Thanks

 

Yes you can run it in all three holes.

 

Yes you can use it for all 3. I use synthetic in the engine, but prefer Formula+ in the primary and tranny. I have talked to a few mechanics that all suggested sticking with Formula+.

 

Why did they suggest sticking with the Formula+?

 

I got mobil 1 Vtwin in motor and run Amsiol 75/90 Severe syn in the tranny and Amsoil Super Shift in the Primary. SMOOTH.....

 

I believe you can, but I put Mobile 75W-90 in the transmission, and I have been riding like that for almost 27K miles on my new bike, without any problem.

 

I run Mobil 1 75W/140 in the tranny. I can justify it for the hot Florida summers and it shifts velvet smooth. V Twin 20/50 in the engine....and usually in the primary because I'm too lazy to try something else.

I don't think 20/50 in the tranny is the best choice.

 

As stated in previous post and on the containers, yes you can put it in all three, however you may decide to do differently. There are several threads on this subject, do the research and decide what's right for you.

 

Sure can. Makes it easier just having all the same for each hole.
