Mike. I wonder if any of the O2 sensors are "less" succeptible to
leaded gas? 100 octane is the minuimum analysis...I recall accepting
the delivery of a truck of av gas at a local airport that had an analysis of
119 octane... . High Octane gas is regular gas with additives...to slow
the burn mainly...everyone knows this I guess?
>>>>>>>>>>>>>>>>>>>>>
>From what I know.. Which I will admit is not enough... may not be totally
accurate. My friend drives a gas delivery truck and has done so for over
40 years. he has been in the refineries, as well as the pipeline
terminals... and he has told me that there is what is called " house
gas" which comes in regular "house gas" and premium "house gas" .
Example, Texaco refineries do not refine Texaco gas. They refine "house
gas" when the gas hauler pulls up to the loading dock and inserts his load
card and enters the amount to load.. The computers will mix in the
additives into the house gas specified by Texaco then it becomes Texaco
gas. Auto fuel does not sit in tanks for months and months... it is
designed to run through the system and be consumed within a couple weeks.
Av gas on the other hand because it sits in the tanks for much longer times
has to be refined in such a manner that more of the impurities are removed.
This extra refining is in large part responsible for the additional cost.
That added to the supply and demand at the local airport,,,, the fbo has
it and you need it,,, and generally there is not an av gas station on each
and every corner,, so the competition or large volumes discounts is not
there.

Reading on the net...appears that MMO has phosphorous as its active
ingredient... Dump a few ozs in the tank and carbon and sticky rings

shoulder... :-) Herb
WHAT IS IT?
My own understanding from earlier articles on the subject is that
Marvel Mystery Oil is a light viscosity oil, roughly equivalent to an
SAE 3W, containing (among other things) about 20 percent solvent
(probably mineral spirits), dye, wintergreen for smell, and 790 PPM
of a phosphorous additive.

Can a 2 cycle or 4 cycle motor, tuned at sea level, become way too lean,
if a person were to fly it at 10,000+ feet? If it is possible for this to
happen (climb into a lean condition), at least there are gauges that may
help them take a different tuning approach.

Subject: | Re: 100LL fuel additive |
Not a scientific test you understand, but when Arty and I took our Texas
trip a couple of years ago. I had a 503 and used MMO in my fuel. We flew
for 40 some hours, using 100 LL when it was available which was most of
the time. Just a WAG on my part but I believe we used in excess of 120
gallons of the stuff. We flew for 2600 miles total. I changed the spark
plugs when we returned and there was enough lead on the plugs that my
mag checks showed a noticeable change. Not enough to be concerned about,
but there was a small build up. Of course the recommended change time
frame is 25 hours I believe, so it was no real surprise that they were
showing wear.
Now having said that, that same engine when I sold it at 185 hours
showed no carbon at all on the pistons and no wear on the cylinder
walls. It had never been decarboned. I had always used MMO in my fuel,
and will continue to do so. It damn sure doesn't hurt and I believe that
it helps a lot.

I've never used it, but it was quite popular and a lot of guys used it
religiously in older airplanes when 100LL first came out and 80 was hard to
find... a lot of aircraft engines had trouble with lead fouling the
valves. Me, I just ran mogas instead (leaded regular and no ethanol then).

Mike:
TCP was developed during WWII to control lead fouling in high
performance Av-engines using 115-145 octane heavily leaded high-test
gasoline....
I believe Shell Oil marketed it first after the war. I ran a 165 hp.
Franklin on 100 LL for 9 years...This engine was low compression and was
designed in the 1930's for 80/87 octane gas. The Alcor TCP was the only
way I could keep from having to pull and scrape the bottom plugs every
20 hours (the Franklin used 14mm automotive type plugs and the
electrodes were prone to fouling.) With the TCP, they would go 100
hours plus on the 100 LL.
TCP makes the lead ball up into globules and blow out the exhaust, vice
depositing on the plugs, valves, piston crown, or whatever.
Not sure what it would do in a 2-stroke or Rotax 4 stroke engine...
Worth what ye paid fer it..

Me too!
In fact I use it in everything I own, except the weed eater and chain
saw two strokes.
Got sponsored by Alcor TCP on my 2001 flight to Alaska. It worked well,
but was hard to handle. Warnings on the can was enough to scare me. It
is very expensive.
No sponsorship in 2004 when I flew back to Alaska. This flight I used
MMO. It worked well, smelled good, and had not scarly warnings on the
can. Was relatively cheap, available at Walmart, so resupply was not a
problem. Did not have to haul enough for the entire flight.
Does it work. I think so. It has been used by aviators and a lot of
other folks since 1933. I have seen miracles happen with some of my old
tractors that are a few years older than me. Back in the old days, I
have watched crop dusters dump it in the fuel tank by the gallons.

Subject: | Broken exhaust bracket |
I don't know how many of you read the Rotax forum also, but if you do you'll remember
that I have an exhaust leak. Here's the thread:
http://forums.matronics.com/viewtopic.php?t=55938
I first tried to simply replace the outside exhaust gaskets. That didn't stop
the leak. So today I replaced the inside exhaust gaskets.
Since Lucien also mentioned checking the support and since I had been noticing
lately that the rubber bushings on my exhaust mount were looking pretty worn AND
since I had it all apart anyways to replace the inner exhaust gaskets (those
were a challenge to scrape off the cowl), I decided to go ahead and take the
mount apart and inspect it. Should have done that sooner! I attached a picture
of what I found. The rubber bushings were useless and the bracket (or plate?
whatever it's called) on the exhaust has cracked all the way through.
I've also attached a picture of my exhaust with the mount with some letters pointing
to various places.
The male rubber bushing was currently where letter A is pointing (actually inside
the exhaust bracket or plate).
The female rubber bushing was currently where letter C is pointing.
The people helping me say that the male bushing should be where letter B is pointing
(between the exhaust bracket and the exhaust mount).
If it is currently set up wrong that might have further aggravated and caused the
crack (besides the bushings being rotten).
I know there aren't many of you out there that have a 503 anymore and probably
don't even have the same set up for the exhaust if you do have a 503, but if you
have something similar could you please post a picture and/or diagram?
The CPS catalogue shows a mounting kit that uses a bolt-driven mounting clamp...does
anyone use that?

Cristal, a couple of things I see in the pictures:
1) the reason it cracked is that you have the old style single-jointed muffler
with one set of 3 springs. These older mufflers are prone to cracking.
2) it looks like the previous owner may have welded a washer to the muffler where
it cracked. Maybe the weld job had the opposite effect and weakening it instead
of making it stronger.

Subject: | Re: 100LL fuel additive |
So, for those who use it, what is the mix ratio? When using the MMO .
1 oz per gal, 1oz per 5gal?? And do you add it over and above your regular oil
mix or substitute the oz or so of MMO for part of the oil??
I've used it as a fogger for winterizing boats etc for years and had great results
with it in that application.
Thanks
Dwight

John Hauck told me to use 2 oz per five gallons in addition to the
regular oil. I also use two oz of Sta-bil as well. If you don't fly that
often mixed gas goes bad quicker than regular gasoline. Keep in mind
that if you are using Ethanol there is a Marine grade of Sta-bil for
Ethanol, and that is one oz per 5 gallons.
