Status: offline 		I've been running Byron a long time now. Recently people have been saying that because Byron mixes by weight they have less oil than a Fuel that mixes by volume with the same percentage of oil listed.

Is this true? Does the oil weigh more than methanol?

Status: offline 		Both castor and synthetics have roughly the same density as water while methanol is a bit under 80% of water. If you mix your own fuel you'll see the oil just fall to the bottom until you shake it up.

As for Byron's..this was talked about over on SSW maybe a year ago and it seems it's mixed by weight. One of the guys did an evaporation test and fuel that was labelled 17% turned out to be more like 14% by volume. Mixing by weight is an excellent way to do it but only so long as it's to give the equivalent volume at a standard temperature (which is harder to do) and not to mislead. I'm only repeating what I've read on SSW because I've never even seen Byrons let alone tested it myself.

Yes, doing the math using a handy little calculator that hauckf came up with. This is what you get comparing what is on the Byron label measured by weight vs. volume measurement at 20 degrees C (68F).

Byron Volume equivilent
0% nitro 0%
18% oil 14.85%

10% nitro 7.45%
18% oil 15.33%

15% nitro 11.36%
18% oil 15.59 %

30% nitro 23.92 %
18% oil 16.41 %


I'm not slinging mud here, these are just the facts.

Status: offline 		I found some numbers from a post on SSW.
Specific gravities at 20 - 25C

Castor 0.96
Methanol 0.79
nitro 1.136
Ucon 0.997

So you see that all the more expensive components are more dense than methanol. So 10% nitro by weight is thus less than 10% nitro by volume. It would be nice if the fuel manufacturer put on the fuel jug or can whether measure was by weight or by volume as the two measures are quite different.

Status: offline 		I used this fuel for about 15 years in the 80s-90s. While I have never had any problems that I know of it does disturb me to find out that I have been paying a premium price to get less nitro and or lube than I could have gotten with other brand for about 1/2 the cash all those years. Heck after getting back into glow Aircraft after a 9 or so year break I purchased 2 gallons of Byron's! I am going to try some of the other fuels that people have said that they are using. I think I may prefer the by volume method.

Status: offline 		A friend was running Cool power 15% in his Saito 72 the other day and we switched to 10% byron fuel 18% oil. We had to richen the engine to prevent it running lean. I thought that if Byron had less oil and nitro it would have had to be leaned. It funny how things work.
