Acetone to the rescue

[elninoalex]

I've seen some debates on putting acetone in your gas tank for lower emissions and higher MPG. Well I finally have some of my own results. I took my 1991 Toyota Previa Van to smog test it on Thursday and it failed on HC and CO. Friday night I put four ounces acetone to seven gallons 87 octane and retested on Friday. Here are the readings:

HC...................CO....................MPG

Thursday
4.34g/mi...........114.5g/mi...........13.42

Standard
2.40g/mi............80.0g/mi............N/A

Friday
2.08g/mi............33.0g/mi............15.19

So, HC are down 52.1% while Co are down 71.2%. And mpg(I'm not sure how accurately they can measure with their methods but...) is up 13.1%. Quick, someone run and go tell the Feds. Oh wait nevermind, a dirty enviornment is more profitable to the oil companies. Politics aside, this is pretty cool. I tried it on my 84 Suburban that wouldn't pass last year. It passed with 0.00 CO.
