100 Octane leaded gas, cheap

Jackson County, North Carolina

Here's the story just told to me. The manager at the airport in Jackson County , NC has to dispose of 1500 gallons of 100LL avgas. I don't think he can pump directly into a vehicle. (road taxes). Selling for $2.50 a gallon.

I'll take four 55 gallon drums please. What do you charge to drive it up to MA?

 

[Don Frelier]

Sounds too good to be true.

In aviation once fuel is removed from a aircraft it cannot be re installed for contamination reasons. I used to get all the JP-8 I ever wanted since they have to pay for its disposal.

You don't wanna run it straight, it has ~ 10x the lead that auto leaded fuel use to have in it. I run 20% for lead content in my old cars, but then again I have a 500 gallon 100LL tank in my yard!

Great deal though at approx 65c a litre or almost a buck Canuck. My fill this week cost me $1.68 liter!

My understanding is that there is nothing wrong with the fuel. It is in an above ground tank. The tank is being replaced and the manager does not or cannot transfer it to the new tank.

I live 300 miles from Jackson Co. airport. Another 1000 miles to MA? $$$$

If I had a towable fuel tank, I'd go get it, myself.

Av gas will burn valves. And ya once its emptied from the piston poppers wings it cannot be reused. Dirt or metal filings could plug the filter screens causing issues .

Not quite that bad. In the 1960's automotive leaded premium had as much as 3.5 grams of lead per gallon. In 1973 the EPA started limiting lead: The new regulations restrict the average lead content, measured quarterly, in all grades of gasoline produced by any refinery to 1.7 grams per gallon (gpg) by July 1, 1975, 1.2 grams per gallon by July 1, 1976, 0.9 grams per gallon by July 1, 1977, and 0.6 grams per gallon by July 1, 1978.

Current aviation 100LL has .5 grams per liter, or just under 2 grams per US gallon. Shouldn't be a problem.

Delaware is about halfway & I can meet you there this weekend attending a wedding. Deal?

Why would a gas burn valves?
Doesn't do it in an air cooled engine. Lead lubricates valves.

Sorry.. brain fart, I was thinking about the old 80/87 AV gas. 100LL has 10 x the lead that it had and it causes problems in aircraft engines with the extra lead both fowling plugs and increasing valve guide wear as the lead deposits work like sand paper. The main reason to cut 100LL @ 20% and only use it as a "booster" to regular unlead fuel is the tolene in 100LL generally dries out the fuel hoses and components used in the auto industry. I learned that the hard way filling my 454 1983 Southwind motor home with straight 100LL to stop the knock. Bastard dropping the fuel tank to get at the hard, rotted out hoses.

As Dadsbee said..
I was informed about avgas and its harm to car engines back in the 80s when I was scavaging all the free avgas from planes being inspected for the 100 hour maintainces

I worked for a small aircraft shop at the time.

Burnt plenty of it in the early 70s with no ill affects. What changed?

 

[dadsbee]

I'd be more certain you burned 100/130 in the 70's that was a much different formulation than current day 100LL. I as you did the same, my father use to bring me home opened barrels of 100/130 that the Ministry of Natural Resources helicopters couldn't take a chance on using, back when he was a clerk there.

 

[mopar 3 B]

The airport called it 130. I either ran it straight or mixed it with Gulf no-knocks 118.
Drag strip fuel always came from a different tank. NHRA would have a cow with the aux tank tie down with the spare tire bolt on the Belvedere. Some of that was way to volatile to put into the stock fuel tank. A remove and dump tank at the end of each run and then burn the remainder of the fuel in the system was the usual. Then a line flush of normal fuel. I have no idea as to what some of that stuff was.

 

[Slap Stick]

Still no explanation why leaded fuel will burn valves.

 

[dadsbee]

It wears out the valve guides first because it's like sand paper, at least in aircraft air cooled engines, and then the valve seat stops sitting straight. Next thing is blow by and then burnt seats and sealing faces. Next comes cracked valve heads..

You're probably thinking of the old (purple) 145 octane avgas, would lead foul plugs in about ten miles of driving. The current (blue) 100LL and the previous (green) 100 octane work just fine in high-compression muscle cars and hotrods.

And yet leaded fuel acts as a valve lubricant on car engines. The main reason for hardened valve seats was the introduction of unleaded fuel in the 1970s. Some friction bearings use leaded babbit material, lead is far too soft to act like sand paper.
