can i just use reg royal 10 w 40 or do i have to spend the extra 5 on the motorcycle oil running the honda gp4 now

 

amsoil 10-40 all the way. I wont use anything else in my bike. Its worth the extra 5 bucks

 

bet thanks i dont think of have any dealers around i want to do it b4 tonight

 

well just make sure you have a good synthetic oil rated for a wet clutch and its 10W-40. I usually go ahead and get the best fluids i can for a bike whenever i can, oil, coolant, brake fluid, headlight fluid, you know, if it takes fluid i get the best their is because i abuse my bike and it needs all the protection it can get.

 

In past bikes and current i have run amsoil, royal purple, and now i use mobil 1. I have had no complaints with any of them, or any poor wear to my knowledge. I generally buy whatever of the 3 i can get the best deal on, as an auto tech i have some local hookups. In my old gix (ran it to 87K miles) i used almost strictly royal purple, as i had a good hook on it. Lost that one then used amsoil for a while in my 2nd gixxer, again 40k + and no issues. That dried up last spring and since have used mobil1 in my honda for the last 15k miles and agian no issues. So all brings my opinion that as long as you are using a quality product of some kind you should be just fine. Just dont switch back and forth all the time between syn and regular oil.

 

i needed a change bad so i gave the bloodsuckers at the dealer my money went with the honda oil again i kno its mobil 1 have had honda techs tell me that i saw the last argument on a thread dont want to start another i m goin to go with the ams next time

 

all my friends and I support that move to ams. but TK is correct, if you use a quality oil it will be fine, Amsoil is just the hot ticket around here for some reason. I use mobil in my truck and cars and no complaints there. and purple gear oil in my differentials, transmission and transfer cases and no complaints there either.

 

i was just wondering if the was a diff between the car and motorcycle im not really worried bout the clutch im goin to swapp it out probly at the end of the season

 

Yes, car oils a lot of times will have "friction modifiers" added in, these are bad for bike clutches, you want to avoid them.

 

thankyou i went with the honda oil
