We have 100 octane race fuel but the ones around here is leaded

 

Most Sunoco's outside Philly have race quality gas, I think they use red handles for it...

 

I would never use octane booster in my car. You're better off getting a 5 gallon tub of VIP Race fuel and mixing in a little every now and then. Octane Booster over extended use corrodes and builds up deposits in your fuel system.

 

There is a gas station here in Modesto, CA (of all places) selling 100 octane gas at the pump!!! Cool shyte!!!

 

Wouldn't you have to add 1 gallon of 100 octane fuel for every 2 gallons of 91 octane, to end up with 93 octane fuel? It's still a very spendy proposition!

SC~ whos glad he can get 94 octane from the stations around here.

 

I'm surprised you can even get 91 there. At higher elevations they usually sell lower octane gas. When I went on a road trip through the southwest it was not uncommon to find 85, 87, 89 at the stations in higher elevations (like Vail for instance).

 

Just be sure to take of your cats before you use the leaded then.

 

I didn't know that. Thanks. Well, in Germany we get 98 RON I believe. I'll have to check at Nurburgring for race gas. I'm sure they have it, but as gas cost on the economy around $4 per gallon for regular, I can only imagine how much race gas would run!!

 

just curious but if you were to run your car to close to empty then use about two gallons of say 100 race fuel just slighty deluted would that cause any longterm harm just wondering

 

oh yeah i also remember someone telling me about small airports being able to sell you airplane fuel and you can use that also because its a much better formulated and cleaner burning fuel what are your takes on that?

 

Airplane fuel..if its not a gasoline type, but actually JP8 or JP4 probably wont work. Those fuels have a different flas point that petrol gasoline.

Anyone know differently?

 

Having an empty tank and running 100 octane won't harm the car at all. If it's leaded fuel it will damage the catalytic converter. You should only use leaded fuel if you're running a straight pipe. They sell 103 octane unleaded race fuel which works great. I usually burn all of my regular gas and put in 103 for the drag strip or track. Makes a difference. As for jet fuel it's usually around 107-114 rating if I remember. BUT it has different additives in it. I believe using jet fuel falls under the same guidelines as leaded fuel but I may be wrong. I've heard of people using it before so who knows.

 

yea i put 103 leaded gas in my '00 Ninja 9R at the airport i fly out of, GAWD DAMN!!!!!

 

Do some more research before you decide about octane boosters. I know a lot of DSMers who run Xylene mixtures with no problems. It's used as an additive at some gas stations anyways.
