Well i guess this question is for Burns, he seems to know it all. So I wanna know what fuels that everybody runns in there pulling tractors and what makes the difference. What compression ratio work with what fuel. Does any body know?

I don't know if this will help you guys (probably not you seem very set in your ways), but in our 150HP F-30 farmall(dyno proven) we use VP-16 which is supposed to be from 116 to 118 octane. That has seemed to work best. That horsepower is aquired by stroking three inches and boring an inch. Reliable with no middle main bearing.

You might get a manual for that dyno and make sure you know how to use it. I'm sure your tractor runs good, but why does it have 150hp and not 151hp or 149hp?

Toulene or xylene form a chemical or paint supply wharehouse can be cheap octane for blending at 116 or so. Thats all most "octane boosters" are. The S.G. matches pump gas which isn't too suprising as these two compounds are just a couple of the dozens varieties of gasoline molocules. Power can be added by blending in oxygenated fuels such as the alcohols (high octane & corrosive) or nitromethane(low octane with nasty fumes). Richer jetting & increased fuel flow will be required.

Cam 2, in one and 15% alcohol, 5% binders, and 80% soybean oil in the other

I am told that a good rule of thumb as to octane is multiply the first number of your compression ratio by 10 and that should be what octane you need. example 8/1 80 octane, 12/1 120 octane

However this is just an estimate and can vary from engine to engine for best performance.

Billy, burns is probably running 85 octane unleaded to make that piece of sh#t deere fire! Don't take his advice. Get some 108 (any brand) and run it!

Pete, Peter or just plain Dick whoever you are?

If you would like to discuss gas, send me an email rather than waste server space with your non-sense. Oh, I suppose you would need to sprout some balls.

Have a nice day.

Tell up Pete, what type peice of sh*t tractor do you pull? Let us know so we can start poking fun at it. Cordially, Greg H.

The lowest octane gas your tractor will run on without pinging or pre-detonating is the one that will make the most power for your tractor. Higher octane fuel is just harder to ignite and burns slower than the lower octanes.

Get into one friendly discussion and now all of a sudden I'm popular LOL

I'd recommend the lowest possible without pre-detonation/pinging. We run high octane 94 in our farmalls which have the aluminum compression pistons. It seems to work a little better than the lower octane gas. I'll be running Citco racing or Turbo Blue in my JD G. I am around 9.5-10:1 on my Compression Ratio.

What kind of iron are you running Billy?

Burns, you are right on this time. Good thing for us that know-it-alls like pete (or what ever his real name is) waste their dollars on high dollar fuel that makes less power than the correct stuff, makes our job easier at the pulls eh?

At one time, I felt that Turbo Blue was the way to go regardless of the engine. The dyno proved that you can actually lose HP when running hot stuff like Turbo Blue when all I really needed was 89-92.

So if i have 118 octane and only need 100,
how much hp will I lose running the 118?

If you need 100, then more than likely your tractor needs a racing fuel in a non-stock tractor. I don't have an opinion on going from 118 to 100. By adding the high-comp clevite pistons to our A, it raised the compression ratio to a little over 6:1. If you are the type that really goes by the numbers you get from a dyno (not figuring the inconsistancies), I was losing around 4-5 hp by running a gas that was rated at a higher octane than I needed.

Every tractor is different and gasoline isn't the only quick fix to better performance. It's one part of many. IMHO

What gas is rated at 118? Is it a mixture?
