What do you guys run in your bike? I have a 2003 CBR600rr trying to find the best oil to use in it.

 

Honda HP4

 

yeah i have heard Mobill 4Tis good, Repsol is real good supposedly but it's expensive...personally i just pick up Honda Oil....not because i think it's better or worse, just because i know it's formulated to work well with the lube system of their bikes...but really, i don't think you will find a clear answer....when i changed my honda oil out for the first time with new honda oil, i could tell it shifted better, i doubt you will dramatic results in different oils, only marginal sooooo...that's my .02

 

thanks man

 

I just put in shell rotella syn. Works just as well as the Honda and costs 16 bucks for 4 quarts at Wal Mart. Last time I used Honda HP4 syn and it cost 40 bucks for oil alone.

go there, do a UOA, and if you're happy with the results, keep using whatever it is you're using.

 

i read knightsluggers UOA of the HP4 on 600rr.net and was interested to see that after 1500 miles the oil had already crapped out.

interesting, i have HP4 in my 600RR right now, i am sending it to blackstone in about 2000 miles and see what happens. in my 1000rr i used to run repsol 4T until i noticed that the mobil 1 gold cap 15w50 was highly recommended off of 1000rr.net

3000 miles on it so far with no problems, clutch slippage, or tranny issues.

 

It wasn't HP4, it was GN4.

 

my bad,
have you done one with the HP4 yet
