I just moved over here from the sportster side. What is the best engine oil for a 07 road king with 96ci engine. I ran mobile 1 synthetic 15w50 in the engine and 75w90 in the primary of my sporty. What do you all use?

 

Asking what oil to use is about the same as asking what jacket to wear. Personally, i run Amsoil 20-50 in my bikes year round. Use any quality synthetic, change it on time, and you'll be fine.

 

I only run Amsoil 20w50 Motorcycle oil in all 3 holes.

There is a ton of post on this subject. Go to the search section on our site and asked the same question. This subject has been covered a million times.

 

Mobil V-Twin 20w50 all 3 holes. I like syn. for how it handles heat. Lots of opinions in the forum here, do a search, it's been beat to death. Good luck!

 

I run the Amsoil 20W50 in the engine and have stuck with the HD Formula+ in the Prim/Trans, thinking of using a 75W90 in the trans the next change. As most will tell you; do a search, everyone’s different...

 

Redline 20w-50 used amsoil, hd syn, and 360 so far Redline has given me a quieter engine and better cooling

 

Doesn't matter. Use what you want

 

Exactly!!!

 

new oil is the best
