I have tried different

I have tried different amounts of acetone anywhere from 2-4 oz/ 10 gallons. For my car the acetone helps, but less seems to be more. i have gotten my best results so far at around 2 oz per 10 gal. Maybe even a little less will do better??

Pure acetone, pure gasoline, no ethanol. My car had only 42k miles on it at the time and the engine/fuel system was clean to begin with. I think 2000 miles is enough to determine that there is no benefit in my case.

yeah

Yeah it is supposed to help atomize the fuel but I have heard that it doesn't help honda engines much if at all, possibly because they have the fuel vaporization working as well as possible already.

see honda was smart. they

see honda was smart. they said, "who wants to put acetone in their tank?" another said, "yea that would be annoying" so they agreed "hey lets just make our cars totally freaking sweet so nobody has to put acetone in them"

the only way....

The only way I can really see its use now is if you had a mistreated engine, and it restored to near factory. So, on a not very well taken care of car.

Hmm... "atomize fuel"...

Not really buying that explanation.

Also, Honda doesn't do anything special to vaporize their fuel, unless you consider Honda fuel injectors to be any different than the rest.

difference

Yeah injectors and the turbulance in the intake and combustion chamber - remember the acetone is just supposed to lower surface tension of the gas and allow smaller droplets of fuel thus it will evaporate faster.

I been using acetone with varing strength from 1-3 oz/10 gallons and it is inconculsive for me. The reason I continued to run it is for it supposed cleaning properties. Don't alot of the fuel system cleaners have a good percentage of acetone? I'm going to stop all fuel additives once my gas log peaks and see what happens then.

Well, the injectors are nothing special, they're swappable with lotsa other stuff.

Also the only special stuff I have seen honda do for turbulence was on the vx, being really madly dished pistons.

What you need

What you need to look at is the combustion chamber and piston top at TDC and see if there is a squish area - that is what causes turbulance in the cylinder as the piston gets to the top of the compression stroke and makes the gases swirl around in the head.

I shot some Torco into the filler spout before heading to the gas station last sunday and then didn't gas up - I checked in the filler spout a few days later and saw white bumpy stuff looked like sand in the spout but it was soft. I think the oil and PIB seperated due to lack of fuel washing it down into the tank.
