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.

PIB is a common detergent used to clean fuel injectors and valves. There are several producers of PIB, each of which has thier own small chemical modification. Having motor oil as the carrier is probably not the best way to get the additive into your gas since it will burn in the combustion chamber and leave deposits which can cause knocking. You can find PIB in STP gas treatment and fuel injector cleaner. Gumout also uses this chemistry.

If you want to clean the entire fuel system, you need PEA chemistry. This is found in STP complete fuel system cleaner or Techron Fuel system cleaner.

There are some products that have little or no detergent in them like Lucas upper cylinder lubricant with fuel injector cleaner or Sea Foam. The Lucas product is oil with some viscosity improver and Sea Foam is a mix of rubbing alcohol, mineral oil, and kerosene.

Hope this helps you find something that will really work.

PIB (polyisobutylene) is a synthetic rubber? When used in gas to increase mpg a high molecular weight PIB is used...like gum rubber dissolved in lacquer thinner. Read the patent?

I'ye yoosta drink Pib on occasion,,,,,,,,, don't see it anymore.

It's kinda like Dr Pepper, right? I remember it from my military days in the Midwest.

Any further results with this additive? I found lots of initial activity but no follow-ups.

*Groan* Yup the corn is ripe in Minnesota!

hi guys dose this mix pose a problem for the catalatic convert thanks

Also I wonder if diamondlarry was takign in to account the fuel he was adding to his car. If he's adding 5 gals + 5oz of gas/pib mixture does that mean you're using 5gasl + 5oz of gas?

I am still curious about additives but everyone has seemed to go away from them. I did try the EAL and Friction Reducer and noticed no change. The current additive I'm trying is looking more promising but we'll see later.

I wish I had regular driving habits to do tests like this. I've put all of 5000 miles on my Torino in two years. It burns so much oil that I try to drive it as a pleasure vehicle, using it in place of the family Durango only when not transporting other passengers because one of the seatbelts (right rear) doesn't work, one window (left front) doesn't work, and one door (left rear) doesn't open. I don't mind adding copious amounts of oil to it, because I know that as soon as I get a carport built, I'll be swapping in an EFI 302 or a 3.8V6 or something else with an AOD transmission.

I'm even considering using a 4.3 Vortec V6 with a 700R4 because it's a proven combination reliability wise and in a low geared car like this it might do well. Caprices from 1985-1993 or so were offered with it they all got 26-27mpg EPA highway ratings. They weighed as much as this monster, too (the 1996 Caprice sedan weighed 4061 and my Torino shipped at 3980). Even the later bubble Caprices with the L99 4.3L V8 (the smaller version of the LT1) got 26mpg highway.

I will be very interested to see the results of any of the PEA/PIB/2-cycle testing here. BITOG has some threads as well but they're looking at wear and tear and lubrication properties. I don't think they're looking for mileage gains as much as UOA results. But I'll be reading in both places about it. When I do a swap on the Torino I want to keep it in there as long as possible and get the best possible mileage as well. So both focus points are pertinent to me.
