Acetone: Fact or Fiction?

[Joe Isuzu]

Are there any drawbacks from the miracle cure??
I can't imagine something so cheap having such positive results w/o some kind of drawback. Things like this don't exist, do they?

Sure does not only will it clean and add mpg but I honestly think I have better responsivness from it....Science backs all of the above.

Are you taking into account that we get better mileage in colder weather?

I thought it was worse in the winter

I thought the "winter" gasoline mix was worse for mileage. And I was under the belief that warm air coming into the intake was better for efficiency than cold air? Although I guess the A/C being off would help...

Cold air makes power, and LOTS of it.

Cold air is denser, and the cooler charge air temp makes for less detonation.

This is why we try to make cold air intakes for supercharged cars, and why intercooling a forced induction car makes sooo much more power.

This is also why cars run poorly at high altitudes.

More power doesn't equate to better mpgs... A Warm air intake is added to cars who are "Eco Modders"

Optimum air temperature for engines is somewhere in the 50* - 70*F range, according to the former automotive engineers at Car & Driver. So you should get your best mileage then. Temps above or below that range should decrease mileage.

I am personally convinced that mileage goes down when it's really cold (like below freezing) - maybe because the cold air is slower to combust? I don't know... pure speculation on my part.

If you live in a state that has a different grade of fuel in the winter, that may be another cause of lower seasonal mileage, but I thought that the low-vapor-pressure fuels used in the summer in some areas decreased economy, and that the "normal" fuel used in the winter was better for fuel economy.

Sounds like Smokey Eunick...he messed around with heating the aircharge till he died. Even convinced GM at one point...either Camaro or Fbird sported heated intake charge at least one year.....but that 750lb engine made way less than 200hp. What a lump! '70s and '80s....automotive "Dark Ages"

Acetone is also a solvent !! So for example if you had plastic fuel lines it would eat through them very fast.
If you have one of those see through plastic in-line gasoline filters I'd be very careful. Probably should replace it with a metal one.
