 Subject: HOMEBREWED OCTANE BOOST?
IP: Logged
Message:
100 oz Tolulene
28 oz diesel fuel
16oz of octane boost to a full tank = 4 points
increase in octane?
My brother did it at the track last night, noticed
some improvement in times.
other ingredients can be
100oz Tolulene
25 oz kerosene
3 oz ATF
anybody tried this, supposed to be same
formula as the super 100 stuff.

I skip the tolulene and kerosene. I have used the following with great results. I have used 1/2 to 1 quart of ATF to a tankful of gas. I have tried mixing diesel fuel up to 30% with my gas. I have also used Amsoil Synthetic and Yamah Synthetic two cycle oil. I used these mix's on off road baja truck that ran real hot due to 13 to 1 compression and hard running. It also lubed to top half. I never had a problem with fouling. I have tried these same things on daily driver put I basicly cut everyting in half. The two cycle oil in the gas is a trick I learned from modifying RX-7's. They use oil injection and it does not do a very good job at startup and at high speed idle when cold. To combat early rotor seal failure you add two cycle oil to the fuel to make sure the seals are lubed. The side benifit to this is a large octane boost and alot of extra thermal potential!!!!! Remember octane is a measure of resistance to ignition. The higher the octane number the more heat it takes to ignite the fuel. The upside is that most times a higher octane rateing means more thermal potenial. If you engine does not need this then you will not get more power. Triva: In the winter if you do around town drive of short distance it is better to run low octane. If the engine never comes up to operateing temp and the trip is short your engine does not ever reach's the temps needed for complete combustion of high octane fuel. P.S. If you take a large gas can you can buy 180 octane low lead fuel from any airport. We had a guy that put a porsche 911 turbo engine in a VW baja bug. He used to get his gas at the airport. That bug would lift the entire front end off the ground at will. He was running 20 lbs of boost and running the sand dunes.

180 octane @ airports?? I don't think so..
Could it possibly be 100 Low Lead is what you meant?

So are you saying if I put my dirt bike 2 cycle oil in my motor it will increase the octane rating? Therefore increasing the burn temperature and oiling my top end better? This is just hard for me to believe, but I am very interested. Also ATF, automatic transmission fluid in your gas? Is this for real?

Using ATF in the fuel is good for your hydraulic lifters and the rest of the top end. Also Marvel Mystery Oil. I have used ATF thru the carburator to un-stick lifters.
Granted these items were done with older vehicles. I have never done this with any newer vehicles.

Keep in mind that the higher the octain the harder it is to get the mixture to burn, it doesn't add any power unless the lower grade was causing pre-ignition. No stock Dakota motor needs anything other then 87 or 89. If you could put more timing then even the MP PCM allows or use domed pistons to increase compression then maybe you would need some better gas. Some muscle cars from the 60's had big time compression compared with todays motors (like 12:1 compared with 8.5:1). You could also but as much advance as you wanted into the motor just by turing the distributer, they really needed high octane feul, Dakotas don't.

2 cycle oil ,ATF and engine oil in the gas will all lower the octane!! but they will raise the btu's per pound and make a bit more power short term. In the long run they will carbon up the heads and valves ,worse yet it clogs the cat.One trick that works is to run 1 bottle of heet to every 1.5 gallons ,this leans the mix but the o2 sensor makes up for it.The octane goes up 2-6 points.This works best if the gas has no alcohol in it to start with.

100 LL can not be used in a 150 or 152. 100 LL can be used in the 172 though.It is sad that I can not remember this. My first 300 hours were in Cesna 150,152,172, and 182RG. I looked in my professional library and could not find any of my early Cesna Operator Hand Books. I will have to check my mom and dads place. I know it was at least 140-180 octane. I remember that it was higher in rateing then Sunco or Citgo's 120 octane raceing gas and it was about the same cost. I do not fly anything that does not have a turbine in it anymore. This much I do remember though "152 = blue fuel"

Avgas for general aviation aircraft comes in
different grades and colors:
Red Fuel: 80 / 87 Octane
Blue Fuel: 100 LL (Low Lead)
Green Fuel: 100 / 130 Octane
Purple Fuel 82 Octane
http://www.prop-liners.com/avfuel.htm
Most General Aviation planes run on Blue
100 LL Fuel. Some older planes, and STC'd
planes can run on Red or even AutoFuel.
----
For putting ATF In the fuel:
I was told by an old mechanic that they put ATF
in the fuel for diesel engines to clean fuel
injectors. However, he warned me that this may
not be good for gasoline engines since it may
foul the Oxygen Sensor.
As fas as ATF helping Lifters:
ATF in the Oil in a small amounts will help to
clean out the lifters. This is due to the high
detergent quality of ATF.

Sandman,
I know we're getting off subject here, I just don't want people running down to their airports and getting disappointed about there fuel selections. It used to be you could get as high as 115/145 octane at airports but those days are long behind us. I believe it was in the 80's that the EPA cracked down on the use of TEL (tetraethyl lead) in aircraft fuel.
Grades of Aviation Gasoline
in the United States
Before EPA Crackdown
73 –
80/87
91/98 –
100/130
108/135 –
115/145 –
Today
80
100, 100LL**
** LL = Low Lead. Grade 100LL contains less tetraethyl lead antiknock additive than Grade 100.
As far as availablity it's pretty much down to 100 LL nowadays, the 80 and 100 leaded as all but gone anymore..There may be certain areas you can get them but not many, if at all..

Yeah in the 'good ole days' my friend and I used to take our cars to the airport to fuel up for the Saturday night 'circuit' runs down in Asbury Park, NJ. He was running a '70 Nova SS 427 L88 with 13.4:1 compression. I had a '66 Chevelle SS 350 LT1 12:1 compression. Those cars loved that aviation fuel and ran like hell on it, LOL.

I just couldn't figure out how putting trans fluid in the gas would be good for the lifters since the gas never tuches the lifters.

Same question as above sounds like voodoo chemistry too me I wonder how many of these self styled fuel chemists have a degree in chemistry. None I'll bet unless they are lyers.

Thanks Guys. It is said what you can forget. There is one thing that can not be argued. Adding lubricant to fuel will act as a top cylinder lubricant. While I am not a chemist I do know that as long as you do not produce a corbon problem or an ash problem then all things being equal our engines will be happier with less friction. I am thinking about trying Amsoils ash free synthetic two cycle oil. I also know that the Dyno showed higher numbers for my old truck when I had 1/2 quart of ATF per 10 gallons of gas.
