Locating higher octane gas (Phoenix, Glendale: purchase, cost, airport)

[lewdog_5]

I am having trouble finding out where I can locate higher octane fuel in the West Valley. Glendale/Avondale area, although I don't mind driving a bit. Most pumps only go up to 91 that I notice? Not even options for 93. Any help on this?

You won't find it in any AZ pumps. 91 is it. Several other western states have similar restrictions.

What about just adding 104 octane boost?

Pleasant Valley Airport used to sell AV gas. Would fill your boat or jerry cans. Lake Pleasant Pkwy and 74.

Look here as well. http://racegas.com/fuelfinder

Glendale Airport used to sell AV gas to walk ins, but do not even think about putting it in a street car, it is leaded fuel and will destroy your catalytic convertor

My buddy and I tried to use Avgas in his 66 Nova 12-1 compression sounded like a diesel engine he had to use race gas mixed with pump gas ended up lowering the compression. E-85 is way better if you can tune your engine to run on it at least for HP if that's the purpose of finding higher octain.

Aircraft engines never run high compression they don't have to worry about needed high octane. Avgas has lead because the old style engines need it. I heard the FAA is working to get rid of avgas replace it with unleaded they are trying to figure out a new fuel I'm sure the cost for fuel will go up.

I mixed 93 and E85 to create about E25-E30. You absolutely need a tune to actually take advantage of the higher octane, and with ethanol you may need to look into the limits of your injectors and fuel pumps from the in tank low pressure fuel pump to any high pressure fuel pumps on the engine you may have.

Naturally aspirated cars can take advantage of E85, but turbo and supercharged cars benefit way more.

you are mistaken, there are a very large number of engines that have high enough compression to require 100 octane and a large number of them are turbocharged so that ups the octane requirement as well. Also, aircraft engines require a higher vapor point to prevent vapor locks, as well as using some of the fuel for cooling. Think of your average general aviation engine as a VW beetle engine on steriods.

Well...if you look at the list I posted above...you don't have to go find AV gas...plenty of places around that pump 100+ octane or where you can purchase racing fuel.
