For tractors that dont get used a lot, we use the 100 low lead from our local airport. Keeps very well, doesnt varnish like regular automotive gas does.

We run 120 octane Renegade brand in our pulling tractors. This guy just won the 5500 lb Classic, $1000 winner takes all at the Sigourney IA. pull with his JD G and some of our fuel.

And you blame the diesels for the foul air in the pulling arenas--And it's been the sparkplug tractors all along---Tee

You better look over your shoulder--I'm watching you!!!

There is no one correct answer to your question. Too many variables such as rpm range, compression ratio, combustion chamber design, etc. Most bone stock tractors will run just fine on 87 octane. Modified engines require the knowledge of what's inside, and a dyno to help in selecting the best fuel for that particular application.

What Mike said. The key thing to remember is that high octane gas gives you less power than regular. If you have increased your compression you may need high octane to slow the flame to prevent pinging which will hole your pistons. If not, the faster burn of regular is what you want.

As others have said, lots of variables but in general around here we can get off road or recreational gasoline which is ethanol free and 90 octane that seems to work really well in my antique and garden tractor pullers with slightly raised compression.

Has any one else run this fuel with good luck. We run VP 120 in one that works good and the kid is running a Oxygenated fuel in his and it seems to work good also but man does it stink poring it in the tractor.

Since this is in the pulling section I assume you are interested in HP. The octane of gasoline is simply it's ability to be exposed to high temperature/high pressure and wait for the spark to begin combustion. Once combustion begins the flame front proceeds in a controlled manner across the combustion chamber until combustion is complete. There is no energy or HP contained within the octane. In this regard using a fuel with a higher octane value than your engine requires can not add HP.

Increasing the compression ratio of your engine will provide significant increases in HP. The higher octane gasoline is then required to maintain the combustion process in a controlled manner (without detonation). The compression increase brings the HP and octane simply insures orderly combustion.

An exception to the above, are the oxygenated gasolines which contain a small amount of oxygen within the fuel. Since there is oxygen in the gasoline the mixture can then be enriched for a small increase in HP without increasing compression.

Both of these John deere As are built
good as for one is for pulling only the
other u still can do thing with on
premium fuel. I know that just switching
to the fuel he was able to go in a higher
gear and spine out. We all so tryed the
120 VP in a stock tractor to see on how
it would do and that also in proved in
running and pull in a higher gear. So it
seems that the stock tractor will in
prove with better fuel. It took me awhile
to get my freind to use some in his
pulling wc Allis an now he runs it with
good power. Yes it is high dollar fuel
but seem to be cheaper then motor parts.

I did not find VP-120 in the listing of VP Fuels. By any chance, was the fuel used in the stock tractor oxygenated?

I know of 24 different pullers running it. Last week at Lincoln a competitor running a 560 IH tried some. I had told him it would run cooler, use less fuel and have more hp. After the pull he told me I was right. The difference was noticeable.
