REFLECTOR: Mogas

[Chris Barber]

The five county area around Harris County (Houston) is prohibited by government mandate from selling e-free gas. Pisses me off. I keep my test strips partially submerged in a can from the station across the street from Ellington Field.

I am one of those that had to redue my strakes when Jeffco failed badly. EZ-84 used the next time.

I have considered buying a trailer with a tank in it to get pure has. At around $7 buck for avgas it may be worth it for my rotary.

All,
Years ago I ran my Long EZ exclusively on 93 octane Super Unleaded from the retail pumps in San Diego: 550 hours with great results. I had the 0235L2C that was famous for lead fouling the lower four plugs. UL 93 octane solved the problems. I am noticing here in Texas and last week on my trip down to Florida that many stations are advertising Ethanol Free gasoline in all grades with even Iphone APPS to find E-Free gas stations, here is a link to one of the web based station finders:

I have followed a few of the threads on Mogas and additive concern on eating Jeffco etc. My question this, is anyone running Mogas in a Lycoming or Continental currently? Auto conversions? What is your compression ratio on Auto Conv's?  I need to track down my compression ratio but believe I'm at 8.9 to 1, and that 93 octane should be sufficient to prevent detonation.
I had such good luck with Mogas in the past I was disappointed in the govt's decision to add ethanol with the issues it can bring to piston aircraft. Now that E-Free gas is becoming increasing available I want to explore it again. Will some of the new additives eat my airplane? Mogas didn't use to do that....
