aviation fuel in 64 fuelie

Re: aviation fuel in 64 fuelie

Here in Florida I find it neccessary to add avgas to my fuelies in the hotter months to avoid perculation and vapor lock.

THAT'S why I use it on occasion, but I do have to admit that since I started using the NO ETHANOL high test, my 63 runs like a scalded dog.

Runs like it did in the old days, pre-ethanol.

I currently don't have a precise mixing formula, but I will say that I now only use the non ethanol high test from the pump. When I get to the local airport, I'll fill one or two 5 gallon jugs with 100LL AvGas.

A few years ago, I used to buy a 5 gallon jug of CAM 2 on occasion, but the price down here is pushing $8.00 per gallon now.

Re: aviation fuel in 64 fuelie

i remember now that it was 100LL. the other tank was jet fuel. i at least knew i didnt want that. i paid $6.99 a gallon. i didnt think that was too hateful compared to the $4.00 a gallon premium.
could the fuel injection lean/rich mixture affect how the engine will burn the higher octane fuel? and that could be affecting the temp? i'm just trying to rationalize why my car has been running great up until adding AVGAS. i had an issue when the engine was 1st built with vapor locking but we cured that with the early style spill plunger.
thanks again for all the help guys. i am taking this car on a 2 1/2 hour trip sunday to lancaster,ohio for a vette show and i thought i would just run some good fuel through it to clean it out so to speak.
take care,
matt

About the only thing the early style spill plunger is good for is sticking in its bore and failing to move easily. Not much of an advantage to that!

Re: aviation fuel in 64 fuelie

I have a 64 fuelie that the engine was never taken apart (except to have the FI unit rebuilt) and I use 112 Sunoco racing fuel leaded, and have NO problems with it. The water temp stays @180-190, no vapor lock, no engine knock, just runs good. The car has 69000 miles. I don't mix it with anything.

Re: aviation fuel in 64 fuelie

Matt,
When I first broke in the engine in my 57 fuelie (low HP) I used 100LL without any problems.
Since that time I have used Shell 93 octane. I was told that it contained no ethanol but as we know, here in Ohio there is no requirement to state alcohol content on the pump.
My car runs between 160 F and 180 F on the hottest days. It has never failed to start on the hottest days and thats it.
I believe your 64 fuel unit is much better then my old 4360 ( POC per JD)and you should have no problems with good gas such as Shell 93. If you do have excessive knocking or detonation then a mixture of 100LL might be necessary.
Good Luck,
Bruce B

Ditto Jim. As far as 100LL goes I can tell you I have been using it since 1990. Test all the FI's with it too. If someone says anything negative about it at the shows I set up at I just smile and nod my head. In life there are negatives aspect to most everything.

Here is a minus factor though. Cutting 100LL 50% with crap gas is not a good thing. Would be like Crown Royal with cheep booze.
Story: My pal FI Art put on a demonstration at the Seven Springs regional in June of 2008 with the LWC (little white car 63). It was 93 degrees that day. Ran the 63 FI car for about 45 minutes with the hood down. Turned the engine off and the temp gauge went to the top. Waited 10 minutes, reached in the window (wrong thing to do) turned the key and the car ran like a clock. Opened the hood and the heat just blasted out. Car was running pure 100LL. FI tweaked just a tad.
Try that with ethanol.
Remember it's only going to get worse. 15% on the way no matter what car manufacturers have to say about it.

Matt, When I went to the GM training center 50 years ago (whew!!!!) my instructor at United Delco said. Never let the gas gauge go below 1/2 tank. He might have said 1/4 tank as I forget. Sounds like you picked up some dirt or crap fuel.
Be careful buying 100LL guys. Like Duke said make sure you know what you are buying. Make sure you didn't get the fuel that's purged from the some of the planes. I have a buddy who is a pilot and he warned me of that.
One more story: My 1928 Model A Ford roadster pickup has some good blue fuel in it right now and it ain't Sunoco.
If it's 90-100 out good luck on making FI's run good.
Dale Pearman had a black 62 with a 400SB and rather ugly 62 FI unit on it. Ugly because he insulated everything known to man under the hood. The car purred in hot weather and the old guy was very proud.

Re: aviation fuel in 64 fuelie

On of the "327 LT-1" owners is a pilot and has many contacts at his local airport. As you said, fuel removed from aircraft cannot be put back in aircraft per FAA regulations, so it's "disposed" in his '65.

His true CR is about 10.4:1 and he can run as much initial advance as he wants on 100LL, but has to limit it to about 10 degrees on his local 92 PON pump premium in hot summer weather.

He's never had any problem with the "used" gas. You can be sure that if it comes from the 100LL pump it's new, but if you can get used for free it's a hell of a deal.

Re: aviation fuel in 64 fuelie

Fellows, how come I can't find some of the high octane fuels without ethanol at stations here in Houston? I'd give my eye-teeth for one of those Sunoco stations.

Re: aviation fuel in 64 fuelie

Has anyone tried MARINE fuel. I am told that your local marine may have no ethanol fuel. Boat motors are having issues with ethanol as well. Just a thought, but maybe there are other issues with marine fuel that some folks on the board may know about....

Re: aviation fuel in 64 fuelie

I have not been able to find ethanol free boat gas on LI and we are surrounded by water, being an island. If any of the LI guys know of any, I'd appreciate hearing about it.

I find mixing some 100LL helps the percolation issue even in the carb engine. The garage doesn't smell like gas after a drive.

I don't know about a prohibition on re-using Avgas drained from a plane in that or another airplane, but it wouldn't be the first FAR I am ignorant of. Mechanics do it all the time when making tank repairs. But, I'm for any rule that gets me free gas

Re: aviation fuel in 64 fuelie

Just called our local marina (Florida!) and they have ethanol free 89 octane. Could there be any other issue with marine fuel when utilizing in our cars?

Dan, several states (including Texas, I believe) have included requirements for ethanol fuels as part of thier State Implementation Plan (SIP). For the most part, this plan is required by EPA to bring non-attainment areas of the State back into compliance. Non-attainment areas are those that have an average peak concentration (of O3 - ozone in this case) higher than the standard set by the EPA. While this regulation is a POS, it prevents more draconian measures from being imposed on industry. Any State that has this plan will have laws governing the seasons and areas that ethanol enhanced fuels are found. Ethanol is added to fuel as an oxygenate and a replacement for methyl tertiary butyl ether (MBTE), which you may remember from the seventies. Now it's being promoted as part of Obama's energy policy for fuel independance. One other thing, EPA has announced that they will significantly lower the ambient ozone standard. Those areas that have problems now will see very significant changes in the vehicles and gasoline powered devices allowed to be sold, the fuels which can be purchased, the availability of transprtation improvement funds, and the industries which can operate there.

Ethanol free 93 octane fuel is all I use in my 66 now. I love it !! These outlets are popping up everywhere now. There's a gas station about two miles from home that sells it. Here's a link to a list of locations.
I even use it in my lawn mower.

Currently in NE Texas Diamond Shamrock has non-ethanol gas.

I use to run 100/130 Green about 2 gals with 10 gals. premium in a LT-1 I could tell a difference, idle and power.
