can anyone tell me what 100 octane leaded is.. exactly.. thanks
the fuel at Terribles is a 100 race fuel made by Torco Racing Fuels for the Herbst Stations, I should know as I sell it to the Herbst.is it the same as av gas and or the high octane racing gas at the terribles in parker?? thanks
100 octane is everywhere ... if you can't find it, PM me and I'll direct you to where you can get it local to you.theres a boat i am looking at along with many others of course, but anyways the gentleman told me it ran on 100 octane leaded, just trying to figure out if its more of apain to get or not. trying to weed out the search..
do either one of those you speak of constitute for 100 octane leaded?the fuel at Terribles is a 100 race fuel made by Torco Racing Fuels for the Herbst Stations, I should know as I sell it to the Herbst.
Av Gas is a aviation fuel that has a higher octane rating than pump gas that people use in their boats to avoid the higher cost of race gas.
both do as they both have lead in them ... but AV gas is AV gas and is rated on a different scale than the MON & RON numbers we normally use.do either one of those you speak of constitute for 100 octane leaded?

I've posted this before & will again here:
A lot of people will run AV gas and love it, but is it giving you the power you could have on the water? No, not really.
Educate yourself and then make your decision ...
I wouldn't substitute Aviation Gasoline for racing gasoline unless your race engine operates at 10,000 feet altitude, and does not exceed 2800 RPM.
Many people see Aviation Gasoline (AvGas) as a way to reduce the cost of their operation. This may be true, but if you want the most out of your engine and want to avoid problems, AvGas may not be your first choice. AvGas is a good gasoline for low speed aircraft engines that run at 2700 to 2800 RPM at 10,000 feet or higher.
This does not mean it is a good gasoline for high performance engines operating at 4500+ RPM. (AvGas is also illegal to use in anything except aircraft engines. Violations can carry a potential penalty of $25,000 per day of violation. But they still sell it at the river)
AvGas octane numbers are determined in a different test than motor gasoline octane numbers. Do not be confused by the big numbers from the AvGas test method. They are not comparable to motor gasoline test numbers. Most 110 race fuels tests at 160 on the AvGas Scale. AvGas is held to tighter requirements than street gasoline.
Some gasoline blenders use AvGas as a blending component to save money. AvGas has a lower specific gravity than most racing gasolines. This means that if a person tries AvGas and has not re-jetted and adjusted their floats, he can burn a piston because the air-fuel ratio is too lean and/or the engine detonated. To make a good comparison between two gasolines, the air-fuel mixtures must be the same. Even after re-jetting, one could experience burned pistons with AvGas if the Motor Octane Number (MON) is lower than what his or her engine needs.
Another potential problem with AvGas is that there are several different octane grades. The 80/87 grade is red in color and can get you in lots of trouble because of its very low octane number. The 100LL is blue and the 100/130 grade is green. Both of these have much lower Motor Octane Numbers than most racing gasolines and will detonate when the engine octane demand is greater than the octane number of the gasoline.
Make sure you do your homework before running AvGas or blending with it.
Here in Coeur d'Alene, Avgas is around $5.25Thats what I run in mine. Avgas, 100LL, whatever you call it, its the same. LL being low lead. Stable for longer periods than "pump" gas, more pure, and higher octane. I'll blend it with 93 also. Obtaining may be an issue, but once you get the hookup on it, stay with it. The cost is minimally higher than pump gas right now.
