torko or aircraft fuel

I was wondering what the difference was between torko blue and aircraft fuel. From what I understand they are both 110 octane, The aircraft fuel is about $2 a gal cheaper. I didn't knowid it would be safe to run in my bbc. ANy help would be greatly appreciated

Well I don't know about the torco fuel but I can tell you that av-gas is very dry and you will almost certaintly need to run a top end lubricant with it to keep from burning your valves or rings.

What compression is the bbc? That's the main factor when selecting octane.

You'll have to rejet and retune the carb. Avgas is less dense than gasoline. Stoichiometric for gasoline is 14.7:1, more like 12:1 for Avgas. It also has fewer BTUs, but not by much. You would get the best performance from 114 race gas, but if you redesign the fuel system and use an upper cylinder lubricant additive, the Avgas will work fine.

Just don't get caught. Using Avgas on the street is a federal offense that can actually land you in jail, get the airport seized by the government, and you might get fined $150,000. No joke.

Don't know squat about Torko

Because of road tax not being paid?

With any government, it's all about taxes.

Also AVgas is 100LL (blue version & most common think their are others...?) so its really more like 100 octane but about 4 times the lead of our old leaded fuel which helps with the upper end lube... Ran it for 2 full seasons in an LS7 BBC (12.25 to 1 compression) all roller motor with no issues at all...

But best formulation for performance is the 114 race gas...

What about if you put it in a vehicle that is supposed to use lead?

No on road vehicle is allowed to use any fuel with any lead in it. Its a federal violation to do so. Lead was removed because its highly toxic and dangerous to the environment. Its illegal to use leaded fuel on the road in any way, shape, or form.

So you can't have a street car running on race fuel?

Its also designed to run at much higher altitudes isnt it? I used it for a while in a motor years ago....and it filled up my fuel bowls with a substance that looked much like cotton candy. It messed up my float level. I beleive it is oxygenated to make up for the higher altitudes and when used at ground level....its just not happy?

Avgas is rated by the Motor Octane Number, an aviation lean rating of how the fuel is when the engine is under a load. Pump gas is rated by the Motor Octane and the Research Octane Number average, the research number being obtained in a controlled evironment and is usually higher by 10 or so points, so avgas is probably more like 105 or even 110 since its rating is for use at altitude where the mixture is leaned out. It's very dry, if you have ever got some on your hands you will know what I mean, it leaves no oily residue so if you run it I'd add a can of Marvel Oil or mix it with pump gas. It has another advantage of being able to sit for long periods of time before going bad, it's pretty stable. You'll have increase your jet sizes to obtain the maximun benefits. Any fuel leaks will become apparent as the dye they use turns into a blue inky substance at the source of the leak. I use it in my boat, but I mix it with 92 50/50, runs great, I never touched the carb but that thing always runs a little rich anyway. It's got a lot of lead in it so don't use it on a car with a catlaytic converter. Airports won't let you put it directly in a vehicle (at least there not supposed to), so bring a gas can if you want some, and don't get caught putting it in your street car.
