| Subject: | Re: HKS and ethanol |
Larry,
I was told by Rotax mechanics that as long as you're flying frequently you
don't need to worry about using regular gas. During the spring, summer, and
early fall I fly with 91 premium (in my 912ULS) since I'm flying every few
days, or at the least, weekly. During the rainy season I switch to non-eth
anol since my flying opportunities are fewer.

My problem with fuel is that I have to drive 130 miles to get non ethanol.
I live in a remote area, so my options are limited. Cost is also a factor.
As far as my flight times, I am cutting back quite a bit. Have seen everyt
hing several times, so some of the shine has diminished.Thanks for the repl

One would think the HKS could handle up to 10% ethanol. The owner's
manual should say if it can tolerate ethanol and what the minimum octane is
.
In any case, are you thinking of going to regular car gas?
100LL is ethanol free and has basically no shelf life, but I didn't take
it that you were asking about 100LL.
Was at a seminar at OSH where they talked about the new G100UL gas that
has been approved by the FAA. No lead and high enough octane to run in
just about anything. Rotax is fine with it for both the 4 stroke and 2
stroke engines. It sounds like that will become available at just about
all airports in the next couple of years as they shut down the last of
the 100LL production.
IN the mean time Rotax is saying up to 10% is fine as long as you get
enough octane for your particular engine. In most places that is either
premium auto gas at the pump or sometimes marketed as ethanol free
recreation fuel.
In the case of your HKS Larry, I would think that if it can tolerate a
little ethanol you would be fine with regular car gas at the pump as
long as you can get enough octane. Just remember that it has a very
limited shelf life so you don't want to stock up on too much at a time.
Also I would think that the occasional use of 100LL would have little or
no impact on your engine.
The only other concern would be fuel system components. Tanks, lines,
pump, etc.
Are you still flying every day you can?
