Hi everybody!!!
maybe is gonna sound stupid but is my first sport bike and I said that is better to ask the pros(you) than to decide by myself, what kind of gasoline I should to use for my 99 F4? is any difference?

 

water

 

lol thats jacked up....you should alwasy use hightest. 93 :-) she likes hot fire.......

 

I always use 92 or higher-mostly 93.

 

my bike has seen 93 from day one. Ran out of gas two times and had to put a little 87 in it and it ran like a 125cc bike However i think the manual only requires 87/89? Anywho, spend a few extra cents and stick with 93.

 

calls for 91, so 91 or whatever it is in your area, here its 93. It will run on 87 but mileage will be way down.

 

thanks guys, very helpful, peace!!!

 

If you use the search option, you will find that a dyno test was done with different octanes and the best HP was at 87(Honda's recomendation) so thats what I always use.

 

yea I always put 87, but after alot of talk on this forum, people have put alot of topics up on this (might wanna try the search button) and 87 is what Honda reccomends...I have ran 87, and ran 93, have not saw any difference, but I just feel better putting in 93

 

well i am using 87 and i get 42mpg
honda says that clear
for track day u can use and kerosine The F4 is easy
