[QUOTE=Duke Williams (22045);365168]Yes, I'd like to read the article. Please post the link at your convenience.

Duke, the article was from Arizona Boating & Watersports in July 2006. Let me know your thoughts on the article. Here's the link: www.azbw.com/ethanolsuspect.php

Hope I did this right, I have not used the Forum much since new format. BTW, thanks for the great explanation on ZDDP and motor oils for vintage engines. Looking forward to your article in Corvette Enthusiast.

What article in Corvette Enthusiast? I've never written anything for them nor had any discussions about writing articles.

The article you referenced appears to have some merit, and enough bonafide evidence to suggest that avoiding E10 in fiberglass tanks is a worthwhile precaution, which leaves race gas or avgas as the next most convenient choices.

Re: BETTER YET!!!!

...when was the last time you saw all these newer, updated mega service stations installing "metal" storage tanks? I wonder if this being true, what is ethanol going to do to all these "fiberglass" storage tanks that most, if not all are using today at some point in the future?

i would bet they now use a different resin that is alky proof.

Re: Ethanol and C2 36.5 gal Fuel Tanks

LL av gas contains 2 grams of lead per gallon. Road grade gasoline only required 1/2 gram to acquire the benefits of leaded gas ie valves etc. The LL name came because some WW2 av gas may have contained 3.5 to possibly 5 (by memory) grams. The av gas and racing fuels start with much better gas blending stocks. I have them for many years and am satisfied with them.

Until approximately 18-25 years ago, there were two types of aviation 100 octane fuel available. There was the "standard" 100 octane which contained about 3.5 g/gallon of lead and 100 octane low lead which contained about 2 g/gallon lead. Each was color-coded differently. The low lead was/is a pale green. I've forgotten what the "standard" was color-coded.

Joe, Our local airport just has the 100LL and it's blue. I like the blue dye as I use it for a leak dedector in the FI's. I test everyone of my restos with 100LL as only God knows when some of them are going to be in service.
Dumb question. If I was to put 100LL in my 84 Corvette with cross fire and cat. converter what would happen!!! The car just sits around as I can't drive it much with my bad back. Thanx, John D.

Re: Ethanol and C2 36.5 gal Fuel Tanks

Way back when there were three types of avgas - 80/87, 100/130, and 115/145, which were all color coded to identify them. Today there is only 80/87 (which I think might be now unleaded) and 100LL, which effectively replaced the two higher octane versions.

The "aviation method" of determining octane number is slightly different than the methods used for determining octane number for road fuels, but the low rating is similar to the MON for road fuel, so the PON of 100 LL is about 104-105.

The high number was determined using very rich mixtures - up to 70 percent excess fuel, and was applicable to highly boosted recips, which are now pretty rare.

Above 100 octane the reference fuel is 100 percent isooctane with a specfied amount of TEL in either grams or cc per gallon (I can't remember which without looking it up). So 105 octane fuel has the same detonation resistance as straight iso-octane with either 5 gr. or cc of TEL per gallon.

Avgas overall has lower vapor pressure than road fuel to help prevent vapor lock at altitude, which is why it tends to be more resistant to vapor lock in vintage engines, but it may result in slightly harder cold starting.

Yes, now that you mention it, I was mistaken earlier. The old "standard" 100 octane was light green; the 100LL is blue.

The 100LL will likely ruin your catalytic converter in the 84. I really don't see any advantage, whatsoever, in using it for that car.

By the way, it's illegal to use aviation gasoline in any street car. The chances of getting caught, of course, are very small. However, the penalties if one does get caught are high. Plus, I'm sure that EPA forces are always looking for cases to "set an example".

There is an "emerging issue" right now of eliminating the lead in aviation gasoline and also of controlling the "illicit" use of aviation gasoline in non-aviation uses. The aviation community, itself, has a significant interest in preventing the non-aviation use of aviation fuel because that issue could be used against the continued production of leaded fuel.

Re: Ethanol and C2 36.5 gal Fuel Tanks

I'm told anytime a plane gets major overhaul, the gas gets drained and can NOT refilled back into it because of FAA rules.
If you want a really good price ask around at the airport repair facilities and become acquainted with aircraft mechanics.Bob

i just filled the 60 gal tank in my trailer with av gas at the local airport we autocross on. 4.50/gal. mike

True! Any fuel removed from an aircraft for whatever reason cannot be put back in any aircraft. I have a pilot buddy with a '65 L-76, and he is well acquainted with the local FSS. His Corvette is the "dump tank" for all 100LL removed from aircraft.
