So Lar, not to change the subject, but what are you going to do with your mark III out at KSAF?



Dunno if you ever get out to the airport but I try to keep an eye on it, as I'm out at the airport all the time...  I usually stroll by to make sure nothing's hit it or anything's walked off....



Sure would be great to have another flying light a/c out there, only a couple of us at this point. And that plane would be a sight. The controllers just loved the FS II when I had it....

It appears that it might start warming up a bit soon, and I'll be out 

there to start cleaning it up and preparing for a new engine.  Anyone 

want to buy 5 acres with a tremendous view in Yucca Valley, CA ??  Price 

is dropping for a quick sale.     When that sells, the new engine 

will soon come along.



I still need answers to the questions in my original 

post.                Lar.

Folks we had that discussion a couple of years ago. What I've done back then is take a bunch of nitrile o-rings and some other rubber parts including silicon and stuck them in a jar of E-85. There has not been any observed degradation in two years.

What does it mean, I am not sure but some alcohol does not seem to destroy the regular rubber stuff that we buy in automotive stores. I guess we can start buying viton O-rings during replacements and that would solve the alcohol concerns.

I've been using 91 octane mogas, sometimes with ethanol.  I've not been 

aware of any problems other than if gas gets older than a couple months 

the engine is hard to start and I don't trust it.  I've assumed gas goes 

stale mostly because of other ingredients, not ethanol.


	


There are concerns about ethanol's compatibility with rubber parts such as 

seals, fuel pumps, and carburetor parts.



Gas goes stale because some of the more volatile components evaporate 

out.  That's one reason I use avgas in my Cuyuna (that and concerns about 

alcohol); avgas is much better controlled as to vapor pressure so it stores 

much better... I believe it's supposed to remain good for 2 years.

In Newzealand I think we use the RON system. I have always either used 91 

lead free or avgas or a mixture of both . 500 plus hrs on 503s no problems. 

Only difference is that the 503 seems to run cooler on avgas and idle a 

little smoother .No performance difference.

I have used both regular and supreme (premium) in my 503.  The regular seems to give me a little lower EGT's (about 40-50deg).  I use regular when I know the fuel will not be sitting in the tank for an extended period.  I use the premium when my schedule is hectic or the weather is iffy and I don't know when I will get to fly next.  I fill up after every flight to keep the tank full to prevent condensation.  I also use Sta-Bil as Larry C. mentioned.  It does a great job; even the left over premix in my empty cans smells fresh after several months.

 Jim swan firestar ll and enjoy flying it.  michigan

You guys need to start looking very closely at your fuel suppliers a lot are

adding 10% ethanol to there fuel.  Recently all of the pantry kangaroo

stores  in Tennessee started adding 10% to there stores. I am not sure if

this is every where they are but they have 1600 stores nation wide.

Six months ago I called the Distributor for Exxon/Mobil in Coeur d'Alene, Idaho and the owner confirmed they do not add ethanol locally for Exxon/Mobil stations.  He did say thay added 10% to the regular for a local independent gas station and sold it as mid-grade at the same price as their regular.  Adding a minimum of 10% gets them tax breaks and they are able to sell the oxygenated regular as mid-grade for the same price as their regular unleaded. 



He said fuel with 10% ethanol or more is required to be labeled at the pump in Idaho.  He also said nobody in his area (N Idaho) adds <10% ethanol because then they don't get the tax break.
