As some of you know that have helped me with outher post i just bought a 2006 crf230f and i was wondering if it is worth the extra money to run premium in my bike then regular. Everyone i know runs premium and i run regular is there really a big difference. I also just bought my power up kit what is the extra tube looking thing in the package for i looked at other websites and no one never mentioned it i hav'nt tried to install it yet.

I dont think there is a big difference. My son did this as a science project about a year ago. He had a 04 230 and he put 20cc's of regular in, started it and timed it on how long it ran. Then he did the same with 20cc's of premium. If I can find them, I'll put his little charts in here.

I have a 07 230 I run premium in mine and have ran nothing else in her. I tried to run regular in my son's 50 and man what a differance. I ran like crap.The throttle response on the cheap stuff sucked compared to it running on premium. I was thinking of trying regular in my 230 but Just haven't gotten around to try it yet. Due to the way my son's 50 ran. My youngest has a knock off quad and it ran like crap on regular also. I know they say it really don't make a differance in cars and what not but I'm gonna stick with what I know works good.

You should be able to run whatever Honda recommends for octane in your machine. If you run less, you may see what was mentioned above.. or you may not. If you run more than was recommended, you will probably just be throwing your money away. If your machine has the stock compression ration and is in good shape you just shouldn't need more octane. A recent study in New York once again proved that. It also proved that it matters very little or not at all which brand of fuel you buy. Each company buys fuel from most of the same refineries and just adds their own additive package.. the thing that was interesting is that the law requires a minimum package and that is based on what an engine actually needs. More is not better.

Having known a chap who checked octane ratings etc of fuel leaving plants there was always a variation (within tolerance)due to commercial reasons.

He was called into investigating what was delivered to a service station and what came out at the bowser.

The standard fuels varied by a much greater amount (lower octane) than premium fuel.

By testing the various brews the oil company determined the some stations do play around with the standard fuel by adding whatever to it to generate more profit.

For some reason they did not find the same thing with premium either due to its lower turnover(less return for their effort) or greater chance of being sued or beaten by owner of more expensive machinery.

I use premium if only because when I ride with others that they can borrow fuel when needed without having to think about it. It is probably a little less fussy in really hot weather as well.

What's the typical octane of premium in Australia?

that tube thing is the seat for the needle. you don't need it unless yours is damaged.

Joe,

Our standard is 91/92
PULP is 95
Best readily available 98

I run the 98 (good for the 2 strokes at our place as well)

What do you guys have?

In Michigan, the regular pumps have from 87 to 94. I can get 95 from Shell gas stations. Some Sunoco's have Turbo Blue at 106 octane.

In California you see 91/92 for premium. There are very few specialty stations that offer anything more. Our regular is in the 87 range.

I run the 91/92 in my 450X without issues. I also buy it from wherever it is cheapest. My son-in-law has a stock KX125 that he bought used. The previous person was running 100 in it that he bought from cycle shops. I told him to try the 91/92 and see. He did and it runs fine.

20 cents a gallon X 2 gallons= 40 cents difference for premium per tank...C'mon man is this even worth thinking about let alone posting.???? Damn I bet you have spider webs in your wallet,.... Christ!

IMHO and backed up by science, all premium gas is equal although some have more detergents that aren't actually needed. Why not get the cheapest stuff? I get most of my gas from Costco where I fill my other vehicles. I save 5-10 cents per gallon. It's not much but does add up. I save enough on the two cars to have a couple of beers! Besides, why pay more for the same stuff anywhere else? If I was gaining performance, then it might be different. I am not actually cheap, I just am practical and somewhat analytical. I read manuals, labels and inquire about stuff. I do my research and then decide which way to go based, as much as possible, on empirical data. It's just me. I know you are a closet analytical too Hank!

The main purpose of the article was to see if there was actually a difference in the way each fuel made the bike run. If the premium gas actually made it run better or not, it could possibly make it run worse then regular if the bike was not manufactured to run off premium but i think the best thing i can do it put a tank in it and see.

to answer my own post i just drained my tank and carb and filled er up with premium and there is a difference in the way she runs. It seems like it tacks a little harder and i know if vibrates more with the premium than with the regular. before running premium i never heard my clutch handel raddle that bad and my hands are way more tingly then before.

There is a black label on you bike. Mine is on the rear fender. Lot's of specs on it including fuel octane requirements. It states 98RON which equates to 91/92 pump octane. The engine was designed and certified to run premium. Run premium fuel and forget about it.
