Question Does xylene lower the surface tension?

So in your gas tank and fuel lines it will either dissolve or suspend organics and those inorganics associated with water into the fuel. Some of these things you may not want in your fuel. Some of these things may form an emulsion in your fuel. I do not know the octane of acetone but I do know the octane of some of the products of it's solvency are awful.

MBTE, now outlawed, formed a snot in old gasoline storage tanks and they all had to e replaced prior to MBTE. Add water you got more snot.

Toluene on the other hand is high in octane and can be added to gasoline, up to 10%.

I wouldn't use acetone because of the problem with fuel contaminants in the products you buy and the reaction they might have with acetone.
confused:does xylene lower the surface tension of gasoline similar to the way acetone does?

I have ran out a couple times when I refilled and in about 50 miles I could again hear the engine ping, notice less power and that tank of fuel got me over 40 miles less. I know of entire fleets using it in their long haul tractors regularly and I know of others that know it is snake oil. All I can say is it works for me. The ratio of concentration is so low that little if any harm has occurred in five years and 50k miles.

With the Lord as my copilot, He may be draining it out as fast as I put it in!

I am glad you feel that it works for you... But, according to my PH'd Certified Petrol Chemical Engr. buddy (head lab honco for 1 of the big 3 gas companies in Hustson) all it does add one ore element to the carbon ring. IE - doesn't really do a thing as there is acetone already oin the fuel to start with.

I have tried dang near everything know to man to increase, HP, gas mileage etc and none of has worked. Buy good gas and change the fuel filter on a regular basis and your good to go. Techron , SeaFoam and StalBil might be the only things that work.

Years ago I heard of this and I tried it in my Harley. On warm days under heavy load (climbing hills) my Harley would ping. Adding acetone made no noticable difference to the pinging or the mileage. I also tried additives like Lucas gas treatment. These additives seemed to reduce the pinging and may have increased mileage very slightly.

A prior post mentioned toulene. I believe Chemtool's B12 carb cleaner uses toulene. That stuff does a great job of cleaning, but if used on any rubber components like motorcycle carb bowl gaskets and rubber gas lines it will destroy them. It will also destroy any plastic components and will instantly remove paint. Rubber components shrink and turn very soft. Maybe gas system components in current vehicles wont react with toulene, but I would not risk the cost of replacing fuel pumps, lines, ect..... If current gas mixtures include toulene it is probably in such a small quantity so as to not cause problems. I would not increase the toulene ratio.

I don't know if acetene reacts with fuel system components, nor would I take the chance.

And among all of us, who really has the accurate and sensitive measuring equipment and the rigid scientific protocols to correctly determine acetone's (or any other additives) effect???? Last I checked, opinion and seat of the pants feel is not a part of the scientific method.

That said, if you THINK or FEEL it works for you then great, do it!!!!

I just hope that in the event of an engine or other failure that the manufacturer (most of whom will not condone additives) does not detect that the additive is in the system and that if you used an additive you won't blame the manufacturer for any fault....

Your answer,
Any refinery will have a complete QC lab. All fuels must meet ASTM specifications. So any additive must keep the fuel with spec. Toluene is the most common replacement component for lead and now for MBTE. It can be added up to 10%.

Very important specs for gasoline are vapor pressure, Sulfur, lead, volatility as measured by distillation and ocatane R + M /2. The fines for being off spec are very high. The country is divided into areas and every month one of the refinery members sends out a sample to each of the other members. Each member them runs a series of ASTM test on the sample which are then compiled and statistically evaluated. The head of the list I guarantee will see weights and measures at their door the next morning.

The blend for each refinery product is determined by the current crude inventory and the value of each maximizing profit and meeting ASTM specs.

forest - Complete agreement, wrong inference.

My performance measurement comment is directed to hearsay/personal claims that adding a can of something to your tank and you suddenly "feel" the difference or over the course of a couple tanks of fuel over varied road/wind/weather/throttle/traffic/etc conditions you can actually measure a statistically meaningful difference when there are more wildly fluctuating variables than a kangaroo farm. Cause and effect

Maintaining ASTM specs of base fuels was never suspect.

If it works for you - Go for it!
