Lately my bike has not been shifting as smoothly as it used to in lower gears and I am hoping that a oil change will do the trick. My last oil change was about 2K miles ago and I put Castrol 10W-40 full synthetic. This time i was thinking about going with Amsoil.

What oil do you guys put in your F4i's and how often do you change it.

Thanks

 

i run mobil-1 10w-30 along with a honda civic filter (any brand but fram) and change it every 3k.. Do a search, there is tons of oil threads.

Here is an example of a search i made:

Rotella T in the blue jug.

 

I have run Mobil-1 and various Honda oils. Both of them seemed to break down quite fast and my shifting would be kind of rough. Now I run repsol blend and I couldn't be happier. She shifts smooth as butter.

 

it seems like lately everybody i hear of with shifting problems is running full syn

 

Rotella-T 5W-40 Synthetic (blue jug) No problemo.

 

I like Amsoil full synth. Last oil change I put in Mobil 1 and immediately started missing shifts that I never missed before.

 

Incognito, you and me both. I had that in to start, did one early in the season, but went with Mobil 1, and it was good for about 100 miles. I'm gonna go back to Rotella 5W-40. Believe the Mobil is 10W-40

 

Why no Fram cageless? Also I run Mobil-1 AND Fram both of which apparently suck according to you guys lol looks like ill have to make some changes....Ive grinded and missed a few gears before or it hasnt gone into gear right away...New rider problem or ****ty oil problem?

 

i ran mobile 1 4t 10w-40 and it was smooth for the fist 100 or so miles after that same problem
