PIB as a fuel additive

[diamondlarry]

Hi everybody. I just found this message on Yahoo! Better MPG group. Vey interesting. I've already ordered my quart of Torco 2-cycle oil and will begin testing when it gets here.

I've just read from members of Bobistheoilguy.com that polyisobutylene
(PIB) can be found inexpensively from some synthetic 2-stroke oils.
The normal composition of PIB in these oils is around 30%. The
purpose of which is to add lubricity to the fuel and allows the oil to
burn cleanly without soot. An example of a 2-stroke oil that has PIB
is TORCO Smokeless 2-stroke oil that, although expensive, is composed
of 38% PIB.

PIB supposedly works by binding the different sized HC's into larger
droplets. The PIB looses its grip above a certain temperature
dispersing the molecules and allowing them all to burn at the same
time. In this paper
http://www.gtatech.com/downloads/OctaneBoosterPaper.pdf they claim
>20% improvement from only 10ppm PIB. Adding this minute amount of
PIB into your gasoline would require one to dilute about 1 ounce of
PIB-containing 2-stroke oil into 1 gallon of gasoline and then adding
only 1 ounce of the gasoline mixture into each tank of gas.
Obviously, a bottle of 2-stroke oil might last the lifetime of the car
it was used for.

The next message in the thread gives some suggestions for usage amounts.
Hi MJ,

WOW... If this works, then this is an *absolutely stupendous find*.

However, after reading the paper, I'm not sure why you would want to add one ounce per gallon, and then one ounce per tankful after that. The paper just said 10ppm (parts per million), which is a ratio of 1:100,000. This seems unthinkable - but so was heavier than air flight, and chemistry is a funny thing.

Seems to me that 0.0128 ounces would work for 10 gallons of gas (1280 ounces divided by 100,000, someone check my math). I'm not even sure how to measure that, this page says 600 drops per ounce http://www.subtleenergies.com/ormus/tw/application.htm if so, then 8 drops per 10 gallons should do it!

Before anybody jumps in, again yes..! I find this hard to believe.

However, I'm going to try it out on my next long highway trip ASAP (probably try an ounce in a tank for starters).

Ah, well, for the second article, I think you're sposed to get it diluted properly, which is good.

I have (vaguely) heard about this in other places. Mainly I've heard something talk about acetone and this stuff mixed and then into the car, but I dunno, certainly something worth testing if you ask me.

Okay, first all post up all the links I can find, then read read read and post up how I feel about this stuff, but PIB is definately worth the effort, from what it sounds. Comparable to the awesomeness of acetone, I think:

I just got my Torco 2-cycle oil today and I put 1 ounce in my tank tonight to start with. I will go to 1/2 ounce/10 gallons in the future. It's probably going to take a fiil-up or two until all of the other stuff in the tank is used up. I'll keep you posted on the results.

[SVOboy]

That's good to hear, I'm going to be testing the PIB after I finish these acetone tests and then the iat resistor thing, I'll prolly end up just mixing it with some amount of acetone, if the acetone ends up working for me, that is.

I'm going to have to redo the acetone test next weekend. I might drive an hour out to Nevada and try it out. I'm pretty certain this is the same test route of Ernie Rogers.

[SVOboy]

Different concentration or what?

[Matt Timion]

Nah, I'll redo the entire thing. If you remember, there was a confound in my testing proceedures last time. One way was uphill, one way was downhill. That in itself would account for the variance in gas mileage.

If anything I'm testing it now to determine if it has a noticable effect on my gas mileage. The Gas Log is 80% done, and after that I'm going to add a experiment feature with a results table for people to keep track of their experiments.

Woohoo, that's exciting. The PM5 chipping is also progressing fairly well, though I've hit the roadblock of my backup ecu disabling the shifter, and if you override it it dies, so I'm going to have to tweak my wiring a bit to disable the ecu know where the shifter is set at, but there are lots working on it now.
