Octane Boost or race gas and pump?

[highdez1981430cr]

I would like to hear about what you have used in the past that has WORKED for you?

1. I am trying to fiqure out the most cost effective way to get to 96-98 octane using the two combined methods of testing that oil companies use.

2.I would like to hear if you are blending race gas with pump to get higher octane.

3. i would like to know where is the best place to purchase the octane boost or race gas.

Thanks Mates

I use 93 pump gas with Klotz octane boost. One can lasts a year.

Ive tried race gas ($6.335 a gallon here) and other than smelling great, I didnt get any performance gain (Seat of pants) and it is stil subject to humidity etc.

I ride a TE-610 and I put some race gas in the tank when I have it available.

The nearest place (that I'm aware of) to buy race gas from a pump is in Indio CA.

I get a 5 gal. can of 114Leaded. Mix 1 gal to 4 gal of Premium. Not more power as such but some protection for valves with the lead and some insurance from pre-detonation (which is hard to hear). That's the story from my dealer. High altitude you won't need the octane but the lead will still soften the blow when valve meets seat.

Suamico SD,

Klotz and blenzall are the two that i have been considering.

Are you running 1 oz. per gallon?

 

[Suamico SD]

Yes, much more (i tried up to 4 oz) than that and it seems to begin to have a negative impact.

Lol, octane booster.......
Taken from Klotz's web site:

1 oz. Octane Booster per gallon of gasoline will raise the octane by 2 ½ numbers.

What that means is if you are starting with 93 octane gasoline, you are going to 93.25 octane. Yeah big improvement there.

I use only VP fuels in my bikes and the results have been great for me. No more contamination of water and dirt in the fuel caused by dirty tank pumps and ethanol in pump gas, better starting, less flame outs, and improved throttle response. I use VP U4.4 and drain the tank after every ride then use VP SEF94 to flush the system out. My bikes are only ridden on the racetrack.

 

[Suamico SD]

Wow I'm real proud of you.

 

[MXRider]

Wow I'm real proud of you.

Good, because I gave info the OP requested. Keep throwing away money on octane booster thinking its giving you more octane. All you are doing is adding in an upper cylinder lubricant mixed with some alcohol.

 

[Suamico SD]

Thanks, I not saying race gas doesn't have higher octane. I'm saying the benefit if a octane booster utweighs the $6 a gal vp. Which was also answering the original question.

 

[MXRider]

But you are not actually increasing the octane by any more than a few tenth's. That is what most people don't understand about octane booster.

 

[highdez1981430cr]

Thanks Suamico SD,

I was going to put in one of my bullet points that i didn't need to hear from you if you:
1.don`t use it
2.don`t believe in it
3.Are a racer and only run race gas

I didn't want to sound arrogant or anything like that i just wanted to keep this thread clean and maybe have it put in the tech section as a reference and not a gas war.


Just looking to hear from people that are using octane boost or are mixing race fuel with pump to avoid detenation.

Thanks for your imput guys.

Octane (higher number) will reduce preignition / detonation on high compression engines. I run stock motors so don't feel the need to run higher than factory called for octane. My opinion is octane boosters are a lot of money for little benefit. An option, with greater availability if you feel you need race gas is to head to your local airport FBO. They would be glad to sell you Avgas. 100LL is at least 100 octane, has 4 times the lead of leaded car gas, and contains no ethanol. Note of caution, if you still have a cat the led will foul it, also the lead tends to foul the aircraft spark plugs over 100 hours, and I would think the same in a bike. Hope this helps

Klotz octane booster is made with Aniline. While it does boost octane it will attack plastic and rubber parts. It makes fuel tanks photo sensitive and brittle. You have seen dirt bikes with gas tanks that have turned brown. That is from using Klotz. If you want to use an octane booster use one made with Toulene.
Most Octane boosters only up the octane by a few points. That is if the gas was an actual 93octane then with octane booster it is now 93.3 octane.

If you are needing more octane (which is only needed in engines with higher than normal compression or bumped ignition advance) then go for straight race gas. I use a blend of gas because I do not want any Ethanol in my fuel. If I can get Non Ethanol pump 93 octane then I sometimes mix it with a couple gallons of AvGas (Straight AvGas is not a good idea. Blended for higher altitudes, constant throttle settings / steady RPM, Low RPM, Low compression, High lead content, and engines that are sometimes supercharged) with 3 gallons of non Ethanol 93 octane. If I can't positively get non ethanol fuel , I will blend 4 gallons of AvGas with one or two gallons of 103-110 octane race gas to give it back some kick.

All the pro racers use race gas, In all my dirt play bikes, I use straight mobile premium gas. I don't race. using leaded gas in our newer engines
will bring back the early problems of lead. One, your spark plugs will not last as long, two it pollutes. When you start seeing those little lead balls
attached to your spark plugs, valves, top of your pistons, you will decrease the performance of your bike. Then it doesn't matter how much octane you
use, you will need a rebuild to get the performance back.

PRO RACERS tear down their engines all the time, we play riders don't. So I would stay away from the leaded gas, and use what is recommended
by the maker of the bike.

If we want more performance we should just get a bigger bike, more cc's. I know it's fun to try and hop up what you got, but in the long run
you're better off with a larger engine, 125-250....250-350 so on, me I draw the line at 350 for a fun dirt bike....a 300 for a two stroke.

Use VP C12, no need to drain it out, no phase separation plus it doesn't stink like ethanol laced pump gas. Maybe it's my imagination but I think the engine runs alot crisper

I use Sonoco 110 mixed 50% with no alcohol 91 octane pump gas. I'm not sure what octane I'm ending up with but I'm able jet it lean enough where the engine runs really crisp with lots of power without having any signs of pinging or detonation. (I did start to have problems with 100% pump gas) A parts man at a Husky dealer told me that Husky recommends a minimum octane of 95 for my WR250. My EC200 GasGas will run good on 91 pump gas. I use Stabil in any fuel that sits in a can or jug wether for a lawn mower or a race bike. The Sonoco mix costs me $6.30 per gal not including premix oil.

Instead of Stabil, try StarTron enzyme fuel treatment. It makes a noticable difference in performance in my car. Stabilizes the fuel for up to 2 years. Even E10. The main thing is to try and stay away from E10 Ethanol fuel. I know it is getting hard to find straight gas. Don't take for granted that the pump gas you are getting is straight gas just because the pump isn't marked 10% Ethanol. Test it before use.

I use primarily Shell Premium (91?) which has no ethanol (here in Wisconsin). I don't have any noticeable predetination or problems that I can discern.

Though when I can, I buy 5 gallons of Turbo Blue (110) and mix that with the premium to 1 part 110 with 4 parts 91? and use that when I can. With that mix I do notice some increase in performance or smoothness- its hard to describe- its like the motor is just running smoother and stronger. That's what I will have in my tank on my trailer wherever I go. When I ride in areas where gas is not as predictable and sometimes they don't even have 9: that's when I benefit from having some of the race mix left in my tank to mix with whatever I have to use-that's the primary reason for me using it. If I carry extra fuel in a small aluminum container- its straight race fuel- used to mix with the "whatever I can find on the trail gas" which is often regular.
