GAS MPG ?? Acetone

[OutLawSE]

Guys,

Does adding acetone to gas really help increase MPG.
I drive 42 mile round trip to work each day and gas is killing me.

Also, does it help lower emissions?

Thanks

this subject has been discused multiple times. and has been tested many it doesnt work.

edit: even mythbusters tested it and said it didnt work.

Why does this come up every week?

LOL

42 miles round trip is like 7 dollars assuming 21mpgs. That is killing you? Are you driving through town and getting 10mpgs?

I put 113 miles on the 2.3 LX every day...


I tried acetone recently. On a 10 tank average, there was no significant difference. Even looking at individual tank data... no difference

You guys should try driving a Jeep Cherokee Sport sometime. How's a manufacturer's rated 16mpg HIGHWAY sound? I can literally drive the Mustang and get the same if not better mpg.

My GMC Suburban gets an incredible 12 and 8 if i'm towing the stang.

The best way to increase MPG is to put higher octane gas in your car which in the end may or may not save you money.

That is complete !!

Unless your car is tuned for higher octane gas, you are just p!ssing your money away by doing this.

Octane rating is the anti-knock capability of the gas, ONLY. It is not a measure of the potential energy it contains. Higher octane gas actually gives up it's energy less freely than lower octane gas, requiring higher combustion chamber pressures and temperatures to burn efficiently.

Running high-octane gas in an engine not tuned or designed for it will hurt its efficiency, and probably ruin the cats over time, as unburned fuel is sent out the exhaust.

Run the minimum octane rating needed to keep from knocking at WOT. High-mileage motors may require an octane rating higher than what they're originally rated for when new because of carbon buildup.

1.9L escort 30MPG average....drive a different car.

All this.... absolutely true.

Couldn't have said it better myself. I hate misinformation. Internet is notorious for it.

You are probably right but that is assuming you are actually getting what you pay for. Personally, I am skeptical as to whether the 87 octane gas offered my local gas station really has an 87 octane rating. Nowadays, both the oil companies and gas stations are finding new ways to maximize profit. I actually ran 87 octane gas in the stang until it started running like crap and getting horrible gas mileage. After switching to 91 I noticed an average increase of 2 miles per gallon after switching to premium and I swear my car runs a lot smoother an quieter on premium. The increase may not be that much but in the end that equates to one extra day without having to fill up as well as a peace of mind that i'm not putting crap in my gas tank. Just my .02.

Well either there is something wrong with your car, or you are faking yourself out, because I tried premium and regular in my car when it was stock and it did not run as well on cold start up in the morning with premium. It effectively acts like you just turn the timing down a little. The gas mileage was not different at all.

Keep the stangs, and get a 4-5 grand 4-banger to daily drive. My little 100k mile 2001 focus gets 28mpg with mixed driving.

My coupe in my sig got a little over 20 when I had it on a long trip, havnt really gotten to test her yet...the big gas saver with a stang is your right foot.

I only paid ~ $500 for my 2.3 Mustang...
I get 28-29mpg (with or without acetone!)

PAID 2400 FOR MY 2.3 RANGER 5 SPEED GETS BETWEEN 25 AND 30 DEPENDING HOW I DRIVE ACTUALLY GAVE ME MORE MONEY TO WORK ON THE STANG SEEING MONEY I WAS SAVING IN GAS

I think it is well known that most people dont drive a mustang becuase their the most fuel efficient car, they drive them becasue their a mustang. I such up the crappy gas prices and drive my truck all week, and drive my car now and than. The high gas prices are just a fact of life that we all have no control over.

higher octane gas sometimes have more BTUs per unit volume. cheaper gas uses 10% ethanol to boost octane up to 87 or 89. but 91 or 93 is purely gasoline with MTBE and no ethanol, thus making a more potent fuel. Is the savings realized overall? Depends on the vehicle. My coworker drove 800 mi round trip on a job in his own car and put 87 in one way and 91 in another. the 91 got so much better fuel economy it saved him money.
