MPG test... (from the acetone thread)
OK, as promised, I dumped 2 oz of 2 stroke TCW3 oil in with todays fillup, 13.1 gal of fuel, 31.9 mpg over 420ish miles (receipt is in the car). Will post back here on wed. with the next fillup results.
car: 2001 VW jetta 1.8t, mildly modded.
Drive: 80~85 mi 1 way (~170 RT... depending on the route). starting elevation is approx 40', ending at approx 2500'. 95% hiway, 2 sections of city driving along the route, both less than 5 mi long.
edit: oh yeah, forgot to mention, within a mile or 2 the tone of the motor changed similar to what happens when I put the 2 stroke in the diesel...

Like in a good way (smoothing it out) or a bad way (like it's gonna vibrate out on you so the flatbed guy has to go back for the engine after he loads the car)?

Thanks for posting up with this.Anxious to hear from a "KNOWN" person on the forum.
Good or bad,it will be good to hear from actual results from someone using it and not just opinions based without fact.I have not started with my Aerostar yet,but will soon.But I think I will be trying the Acetone.
Thanks for the input already.

Taking measurements is to be praised.
However, keep in mind that looking at one tank versus the tank after,
is a very 'jumpy' way to do a MPG test.
I know because I have made that same mistake myself.
Before starting a test like this,
as a bare minimum you should have a few tanks before any mod,
so that you know what the 'natural variation' from tank to tank is.
I found in my tests that it takes at least 8 tank fulls to find something dependable,
and the tanks with the mod need to be in between tanks without the mod.
Looking at only two tanks is nearly useless, especially when the weather changes day to day, like it usually does.
These are not my ideas.
Much wiser men than me (such as Claude Travis)
have come up with good dependable ways to do MPG tests,
particularly in the diesel truck business
where MPG is 'do or die'
and TMC, the Truck Maintenance Council
was formed to help spot 'snake oil' claims.
We should all take advantage of what they have discovered already.

Additives
Many products claimed to improve fuel economy are oil or fuel additives. In addition to the previous precautionary steps, the wary fleet operator will obtain assurance that such a product will not degrade critical oil or fuel properties, such as viscosity and ash content (oil), or cetane rating, vapor pressure, stability, cloud point, pour point and flash point (fuel). Specifically for fuel additives, see TMC RP 312, “Qualifying questions to minimize the potential for negative side effects from an aftermarket diesel fuel additive package." snip Synthetic transmission/axle lube can boost mpg by up to .5 percent in summer, and up to 2 percent in winter.
=====
The idea of adding two stroke oil to diesel has been around a long time.
The big diesel fleet operators like Snyder Trucking, JB Hunt, Walmart truck fleet, has tested this and found that a good MPG test shows it to be bogus. If it did work, it would save these companies literally hundreds of millions of $ per year.
Keep in mind that Walmart as promised to double their fleet MPG from 6 MPG to 12 MPG. They are willing to spend hundreds of millions to do it, not just for the fuel savings, but because Walmart has promised to do this as part of their 'Global Warming' commitment, and they have promised to make public reports on their progress. If adding two stroke oil to diesel fuel had been successful Walmart would have already reported it, as they are testing fuel additives.

well, there you go... abort, abort... have to go to san jose tomorrow for work so the data will be shot since the commute is different. I will post the mpg result anyway. generally when I go to SJ I end up in the upper 20's for mileage (lead foot, heavy traffic etc). I will re-run this test when I'm back on the normal commute. Looks like I could be in SJ a couple of days.
as for the tone... quieted down a tad. never made sense to me how it was able to quiet the diesel, now on the gasser???!
Also I've used MMO in the past as well, never did have a commute good enough to track data on it until this current job.

sample quote
The popular U.S. television show MythBusters investigated several fuel-saving devices using both fuel-injected cars and diesel powered cars under very controlled circumstances.
The concept of fuel line magnets, which supposedly align the fuel molecules so they burn better, was tested and they determined it made no difference in the rate of fuel consumption. They also tested the idea that adding a small amount of acetone to gasoline increases fuel efficiency by making the gasoline burn more completely (presumably without damaging the plastic parts of the fuel system.) However, the result was that alhough there was no apparent damage the fuel system, the efficiency of the fuel actually decreased.
They also tested a device that supposedly produces sufficient hydrogen to power a car by running an electric current through water (which causes its molecules to split into hydrogen and oxygen). Although some hydrogen was produced, the amount was minuscule compared to the quantity necessary to run a car for even a few seconds.
The show also tested a carburetor that, according to its manufacturer, could improve fuel efficiency to 300 miles per gallon. However, the device actually made the car less fuel efficient.
They also determined that a diesel-powered car can run on used cooking oil though they did not check whether it damaged the engine.
The show noted that out of 104 fuel efficiency devices tested by the EPA, only seven showed any improvement in efficiency, and even then, the improvement was never more than six percent. The show also noted that if any of the devices they tested actually worked to the extent they were supposed to, the episode would have been one of the most legendary hours of television. The show also cited common sense by stating that if there really was a device that dramatically increased fuel efficiency, it would certainly be common knowledge.
