Cool The Free Mod Series: Part V How to pick up MPG, and sleep with her too!

Background:

This ties along with FMS VI (and a later un-named article).
Your gas mileage could be great! It could even break the laws of physics... By sucking and blowing at the same damn time. But either way, we definitely need to increase it by any means possible. Gas is getting expensive...

Theory:

Gas additives... All either use something to raise octane, clean the fuel system, or decrease the surface tension of the gas.

Why not use high octane? Because higher octane creates less power... It is *MORE* stable. The only reason to run HIGHER octane, is to be able to run MORE ignition advance than you could without facing detonation (pinging/pre-ignition, it's all the same)

Why not clean the fuel system? Because a $5 can of seafoam does that extremely well!

Let's decrease the surface tension of the gas!!!

This means several things:
It will pump slightly faster, and transfer/expel heat slightly faster. Both of those are so small, it's negligible.
It will atomize better when it leaves the fuel injector. Here's your gain folks!
Fuel will also break up better every time it hits the wall on the way to the combustion chamber (for that matter the valve too)


Instructions:


Mix acetone in a 2-5oz per 10 gallons of gas ratio.You'll have to find your sweet spot (mine is 3.5 in my 3vz-fe, 4.5 oz in the '99 4.6L f150 and 3 in mom's '02 maxima) We want 100% acetone (nail polish or real, the fragrance in nail polish doesn't bother us).
16 oz of nail polish commonly sells for $2.50. 32 oz of Acetone goes for $5-6.5, One Gallon $10.
Acetone doesn't eat away any part safe for gasoline. While being readily available, and cheap enough to pay for itself.

This lexus gained roughly 2 mpg from it. The F150 went from 17mph (avg) 19mpg (best ever seen) to 20mpg (avg) 22.5 (best ever seen). Mom's maxima went from getting 27 (avg) and 30 (when i drive it on long highway trips) to 31 (avg) and 35 (long trips)

If you only get 10% on 19mpg, that's an extra 35 mile range (5 miles more than the distance between your low fuel light coming on, and your ECU shitting your engine off before the fuel runs out) A gallon of acetone will pay for itself in a tank or two. Maybe faster. (someone on a forum reported a prius going from 44/47, to 55)

I challenge everyone to give acetone at least a 16 oz bottle's worth a try! That's the cost of only one gallon of gas in a lot of places now...

Shhhh I have two articles on that for after tax refund time. Both are very $$$ friendly.
One is finished and semi-working as far as I can tell.

Pour 1/2 gallon of water in your gas tank if you wanna break the surface tention of the gas and get better gas milage.

Cool

^ He's just kidding (i hope)

You can't use water in the fuel injection system. Brass, aluminium, and tin parts are used, and they will corrode from the water flowing in the system. Aside from the majority of the system not liking it, water and fuel injectors do not go along. Many have brass inserts inside them. The water will corrode them shut fairly quickly. Gasoline also does not readily mix with water so you would never get an even supply of it.


(Also why you can't just take a spare fuel injector and use it for water injection) Jagwire, it worked on our three vehicles. I'd tell you it works in my civic too, but I never got around to trying it.


Acetone is an Emulsifying solvent. Look it up. If anything else, try it for three tanks. Just be sure tog et the ratios about right.

3rd Generation Gonna try it.... WTF?

Well.... My Camry is a dailey driver.. so.... I don't wanna mess w/that.. BUT I have a 2001 Toyota Tundra... I KNOW what crappy MPG it gets. SO... I will try it on that...
I will report my findings....

It has a 26gal tank...
I will run 2 tanks and see...

If it is true.. or if it is snake oil!

3rd Generation I Did it...

Well.... After reading all the blogs, posts, chemical graphs and forum banter here and elsewhere.. I came to a conclusion. If you do the reccomended .3oz/gal or 3oz/10gal.... that is not much if any at all. So, I went to the Ace Hardware place and got a 16oz bottle of the stuff.. and put a small amount on a glass dish and put a lighter to it. Yes, it burns a faint blue. Then, I mixed a capfull in a glass of 93 Shell V-Power and guess what? Nothing.. no reaction, no discoloration and no water formed.. nada, zip, zilch, nitch, nuthin'.I have a 2001 Toyota Tundra and a 1994 Toyota Camry V6 XLE.
Now.. in order to verify these claims... I have been keeping records of EVERY time I fillup.
I got the Camry in Feb. 2005 with 24,368 miles on it.. long story there.... ANYWAY. I have a spreadsheet I keep with every fillup. I drive 49.1 miles one way to work of which 42.5 miles are pure I-85 highway driving. I put it on 80mph cruise on the highway. I have been doing this since Dec.1st 2004. I have records from Mid Feb till now on the Camry. So far, I am averaging 25.2mpg. I get between 210-225 to ½ a tank. I get 100-115 to a 1/4 tank. So, basically.. I am using 4gal a day of fuel to commute between my home and work.
From what I read... I BELIEVE the gas tank on the Camry is 18.5gal. SO... for a FULL fillup..
It would require .3*18.5 = 5.55oz or (Rounding up) 6 oz/tank Acetone. I am averaging about 12.5 gal per fillup so... 12.5 * .3 = 3.75oz (round up to 4.0 oz)
So, I filled up... and added the 6oz for a FULL TANK.. and from here out will add 4.0 per 12.5 gal fillup to maintain the FULL TANK ratio.
This weekend, my wife and i will be going to Panama City Florida. From LaGrange to there is about 200miles... give or take a mile or two. 90% Highway. I will keep logs and records.. and report back as soosn as I have a measurable, proveable, and repeatable good, negative, or bad fuel report. In any case... I am curious and there is only one way to find out!

You sure about that 18.5 gallon tank? I could've sworn my '94 only had a 16.5 gallon tank. My reasoning for this: I was told that my fuel warning light comes solidly on when I only have one gallon or less. The couple of times I drove it 'til the light came on I only put 15+ gallons in it at the pump. Could it be possible that I was told wrong?
