Aviation gas ?

[Highbanked Hauler]

    Is anyone adding it to regular gas ? Any problem or advantage ?

[ws23rt]

I'm not a good ref. for technical info. but a friend has a small plane and told me the gas is much like we had back in the day.  That is higher octane and leaded.  A big plus is that is will last a very long time in the tank.

In the aircraft world anything that may cause engine trouble is addressed. Such as a plane sitting for extended periods kinda like a lawn mower.

As for mixing it with what we buy at the pump?  It only makes sense that the more the better for the old stock engines that we deal with.

Getting it from an airport to your car can be a hassle and may not be worth the risk. --The tax man needs to be fed to fix the roads

Too bad the gov. that protects us from our selves got in this and makes us add corn to our tank and than the car companies have to deal with it.  They pass the cost on to us as do the gas suppliers.

Most of what we got that sell to the public is like $7.00/gal. And only 100 octane unleaded.
of course, some youthful putz would attempt to put the leaded stuff in his cat. Converter equipped new Challenger and void the warranty so they refuse to sell to the public for this reason.

    Gotcha,   so what octane is the gas they sell at the strip ?  The next option is  E-85  but  those places are few and far between at least here.

There have been many dyno comparisons between straight modern 100 low-lead avgas and race gas...it seems they run neck-and-neck up to a certain compression ratio and then the avgas won't cut it.

As far as adding it to modern unleaded, shouldn't be a problem (without cats) but expect shorter spark plug life due to the lead but the valve seats will love it..

One other thing to consider is the fact it is illegal to operate a motor vehicle on a public street on leaded fuel.
They dye it blue to identify it.

       Obviously you don't run leaded gas in a car with converters that goes without saying.   So whats in the lead additive for  use in a higher compression motor ?

     I've ran anywhere between 2 and 5 gallons of 100 low lead in the Charger with a tank a 92 octane super unleaded and the 440 really likes it. Small airport in town, I just walk up to the pump with a gas can and use a debit/credit card. You can't pull your car up to the pump, not legal. Anyway, haven't done it in about a year since the detonation problem went away.

Unfortunately, lead in fuel was on helluva pre-ignition deterrent, a valve seat lube. Also, it raised octane.

They have changed our cars to run without lead and it has been costly.  But what about us that grew up with lead. The exhaust we were surrounded with while learning to tune cars ourselves. And cruising the main drag on Fri. and sat. night.
You can't even find a good lead base paint for the kids to chew on.

Maybe one can get a supplement at the pill for everything store and share the pills with our old cars.

       Years ago I have heard stories of adding some grade of enamel reducer  and also diesel fuel. I never tried either but it seams diesel fuel would smoke and enamel reducer  would gum things up.

Know several people who run nothing but aviation fuel in their classic cars. Supposedly has a shelf life of years instead of months. I split a delivery with a buddy. We had 5,000 gallons delivered to his place for what amounted to $4.85 a gallon. So now it's in a storage tank.

The shelf life is what makes it attractive to me. I have several cars that sit for long periods of time and the question of the gas going bad is a real problem.  I have pulled the gas from one of my cars for this reason and tried to use is up in my lawn mower. It did not go well.  My always first pull mower needed starting fluid to make it go.  I dumped that gas and fresh fuel gave me the first pull starting back.

What we buy at the pump for our cars today has a short shelf life to say the least.

The question about paying the road tax is simple but when someone like us says ok the answer is still no.

What we are left with is to find someone that knows someone that can get the fuel we want.

We are not crooks we are car collectors and we want to drive our old cars.

It is now legal to buy pot in WA. but I can't buy the fuel I want for my car legally. 

The ambiguous/arbitrary way rules are made leads to criminal behavior.

I run straight 100 octane low lead fuel from my local airport. Thats all I run, I dont mix it or anything, when I need gas I drive up and fill up, but I will tell you there is a pretty decent increase in power compared to running 93 octane from the regular gas station. Also has a good smell to it .
