To all who use Auto fuel,
Here is Bill Mulrooney's response to my brother's inquiry of his auto fuel
/ mogas experience.
For those who do not know, Bill and his partner built a Velocity with a 427
V8...N427VA....it boogies!
Hi
......
"Sorry to hear your having issues also. I live in West
Bloomfield Michigan. I'd be happy to talk to you about your problems and what
I've learned from my problems. Alcohol isn't the problem, it's the fuel injector cleaners that they started adding 9 months
ago. It is such a small molecule it literally slips threw the
Jeffco coating in the tanks. Our tanks look perfect inside but the
fittings in the sump tank and the foam in the stakes just took a shit on us!
I'm still pretty sick about it! I'm going to make the sump tank out
of aluminum and were removing the outer glass skins and foam and adding another
coat of Jeffco to the outside of the inner skin followed by 8 to 10 layers of
bid. Then foam and then the outer layer of glass again. The wheel
wells are about 1/8 " of glass and they look perfect still. Our plane has
had auto fuel in it since 2004 with no problem till August 2012. The vapor
build up between the inner and outer glass and then popped the glass loose
around the fuel fillers on both sides. That was just after Oshkosh 2011.
Then the foam started to sink in on the glass. Then we stopped
flying it. "

I
stopped by my non branded Commercial Fuel Network outlet yesterday and this is
what I learned. While there is no Ethanol in their fuel they service several
stations. IE Chevron, 76, Mobil, Shell etc. Fuel received from the refinery
contains the additives for that company's fuel. Consequently the fuel they sell
to me , as non branded with no Ethanol, contains different additives or blends
of additives from each company. They guarantee no Ethanol but any combination of
additives after that are anyone's guess. So Kurt et al take heed. I'll be using
100LL for now!
