This inane post is too rich.

It's a lot more nane if you don't cut out verbage to alter the meaning.

We use AV gas in one of our race cars. Just go to the pump, swipe the credit
card, fill a 20 gallon drum and drive off. No problem. We find our car is
more consistent on AV gas than racing fuel. And, they call it low lead, but
compared to yesteryear's car fuel, it's not low.

In S. Florida you can pump 100+ Octane airboat fuel right in the tank.

Back in the mid-50s I was driving a '51 Olds 88 'vert (303 cid) with
milled heads, compression ratio probably near 10:1. It "cackled" on
either commercial premium or 96 octane (blue) AvGas. Green, 100/130 was
about right in that engine and gave a plug life of about 5000 miles.
Green wasn't pumped too often on that base--we only used it in a couple
of C-45's (called them SNB's). Purple 115/145 was easy to come by--the
fuel farm pumped thousands of gallons every day (and a few hundred
gallons of "spillage" and "evaporation" each week wasn't a problem). One
of the fuel guys suggested I try a tankful. Nice and quiet but plug
deposits were a problem. After two plug changes in three months, I
re-gasketed the Olds & sold it. Two cars later I got my first 'vette
but never lurked around the fuel farm with that car -- the red 'vette
was not as 'subtle' as the pale green Olds. :-)

Interesting point with both fuels was that spark could be advanced to
the point of diminishing returns without any ping. The Olds didn't
really exploit the capabilities of either 100/130 or 115/145.

Has anyone run nitrous with AvGas ?? ....PJ

What type of racing are you doing that you can pass the fuel test? They
check us all the time both when we race SCCA and Champ Car.

Drag racing. There are no fuel checks and we usually run 110 to 114 octane
racing fuel. It's about $6.00 a gallon.

I have used the aviation gas. 100 octane low lead as they call it has more
lead in it than automotive fuel ever had. The only down side to the aviation
fuel is it is formulated for air cooled aircraft piston engines that are
designed to use just enough oil to keep the upper cylinders lubricated.
Avgas is very dry and will wipe the oil film from the cylinder walls of a
automobile engine which in turn causes premature ring wear. I mixed a little
two stroke engine oil with the gas to help prevent damage. Also, aviation
engines have duel ignition systems for safety reasons one of them being lead
fouling of the spark plugs. Not a big issue in a car but in plane it is a
little hard to pull over at 10,000 feet and change a fouled plug.

Please recheck your facts.

Leaded autogas typically used a lead content of two to three grams /
gallon. Current formulation of 100LL AVGAS uses 0.57 g / gal. This is
why most air-cooled piston aviation engines can be STC'd to use
'unleaded' mogas.

Piston aircraft engines' upper cylinders are lubed about like those in
cars - oil from the sump. Piston skirts and cylinder walls are lubed
(and in part cooled) by oil jets, valve gear by oil pumped into the
heads. Lead additive in gas does not lubricate any part of an aviation
piston engine, including (contrary to myth) valve stems or seats. AV
engines use nice hard valve guides and seats, and often sodium-cooled
exhaust valves, to let the oil do its work. Note also that essentially
all piston aviation engines can be STC'd to use 80/87 low-lead mogas,
and this obviously could not be done if aviation engines really needed
more lead in ther fuel.

Then it'd also tend to remove oil coatings in aviation engines, which it
does not.

In over thirty years of flying piston-powered airplanes I have seen
exactly one fouled spark plug, and it was not lead-fouled. I have never
heard any case of an aviation spark plug becoming lead fouled.
