I tested Coleman, 87, and a known brand high octane fuel with oil added on my test stand a few years ago. Coleman and 87 were similar top RPM with coleman slightly higher. The high octane turned lower rpm's.

squirrel,

You've had now what, 3 folks with hands on experience refute what you're advocating.....

Instead of insulting people and looking more foolish why not conduct your own testing and prove them wrong ??

A nice video of your test results would go a long way in "proving" your beliefs.....

Been there, done that and old enough to know better.....

You seem to be another one too... you would not understand because comprehension of technical information requires advanced skills that you don't have. If it was presented you would claim it is false hence, what is the point. Get a life and heckle someone else.

Present "the facts" by doing your test on video ... you've already been told that higher octane gas actually decreases RPM when used in the type motors we're discussing..... it doesn't take a rocket scientist to conclude that less RPM = less power while more RPM indicates that the motor is producing more power ( all under load).

Perhaps it is you that are incapable of understanding such a simple concept?? But again, prove to us that you are right and everyone else is wrong . You claim to be smarter than anyone else so that should be a simple task for you .....

If you can't, then simply move on ....

Edit: and as far as me "heckling" ???? Nah..... you're doing a pretty good job doing it to yourself!!

You all have the same line every time. Both of you claim to know more from your google/forum education than I and try to discredit what I said. You are not even smart enough to understand what I originally posted.

My original post was not even directed at either of you, so what is your problem and why are you sticking your nose into my post?

People generally "stick there noses" places to keep incorrect information from being accepted as fact when someone posts a question that deserves an answer with proven results.

Squirrel,

# 1 -this is a public forum NOT moderated nor owned by you ......
#2- this is not your thread ....... so it was YOU that stuck your nose into the topic with your rediculous and uneducated post.
# 3- you've been given the opportunity to prove your point but you continue with your same rhetoric...... either $hit or get off the pot . My guess is that you'll get off the pot......
#4- keep digging yourself a deeper hole , we're all loving it !
#5- you can always start your own forum so that you can delete unwanted posts ..... but I'm afraid no one would participate! LOL !!!

So in my scale fuselage I have to actually remove the carb to properly adjust it or even access the needles. I was completely wrong about it needing to be richened up more to remedy the dying out. I have no idea how but I was over 2.5 turns out on the high end... I set it back to 1.5 as a baseline tonight with the SEF fuel and it runs great throughout the throttle range.

@ RM3,

Have you had a chance to do some testing yet ?

BS, squirrel.....you're just spouting crap from EPA talking points trying to force ethanol and "biofuel" on everyone.

It's totally laughable when you falsely claim that using 93 octane from the pump is more economical....when that costs over $0.50 a gallon more....

What a joke....totally nutty....

I have a Wally Hyper21 just sitting around...

so to test what should be the setup?
Im thinking cheap ol 87octane from the gas station, then add 104+ octane booster purchased from Autozone, then buy that SEF ethanol free stuff from Homedepot/lowes?

then prop test the three fuels and note the RPM change?

how would that fair as a definitive proof test that octane does or does not have an effect on HP?

Wouldn't it be better just to take the three fuels from the same pump as to keep things consistent ??

What are they , 87 89 and 92 octane ?

...Yeah, I think just going with the 87 and 93 from the station is more than enough... but just to be sure I may just buy that 104+ and mix it up, if anything is to change ANY HP value it should be seen between the 87 and 104...

I'll see if I have anytime this week/weekend to put a vid test together.

EDIT: Seems a few separate online tests have stated that the best is either Torco or NOS brand... the 104+ is garbage..

When E85 first started being used in cars a lot of people brought their cars into my shop complaining about the fuel economy on E85. I tried to explain to them that it takes more E85 to make the same power as 87 octane gasoline.

would skew the meaning of the test to use a fuel blend that is 85% ethanol vs crude based gasoline.

besides that, it has already been deemed as very bad for lawn care equipment (air cooled, non fuel injected, carb type) and 2 stroke engines...
The Environmental Protection Agency has approved gasoline with 15 percent ethanol for use in cars year 2001 or newer, yet it prohibits its use in mowers and other power equipment, stating it may cause damage. A Department of Energy study found that E15 caused hotter operating temperatures, erratic running, and engine-part failure. But even gas with the usual 10 percent ethanol (E10) could help destroy small engines.

"Ethanol has inherent properties that can cause corrosion of metal parts, including carburetors, degradation of plastic and rubber components, harder starting, and reduced engine life," says Marv Klowak, global vice president of research and development for Briggs & Stratton, the largest manufacturer of small engines. "The higher the ethanol content, the more acute the effects." Servicing dealers are reporting similar problems, even with E10, according to the Outdoor Power Equipment Institute, the industry's trade group..
E85 would make these indicated warnings/results far worse than E10 E15.

good read for anyone interested in why we dont run E85 in 2 strokes:
