95metro about to conduct ambitious (blind & controlled) acetone test - cancelled
Documented on his web site:
https://www3.telus.net/metro/tests/acetone.htm The only comment I suggested to him was to use a looping test route, rather than driving in only one direction on a sample (and back again for the next). A looping, or bi-directional route will average out wind/grade effects. I'd be more skeptical of comparisons made between samples going in one direction against those going in the opposite direction. |
I agree. It sounds like it will be a great test. I guess we need to see if he will let us add that to the busted or confirmed list. Any wagers on results?:D
|
I'm wagering about a 5% variability between all the samples (including the controls), so NO evidence that acetone (or the other additives) is better or worse than the others.
You? |

It will make more improvement if he goes slow with light throttle.

Mark cancelled the test. Running the car out of gas proved problematic, and inconsistent:

Marks too kool. Too bad it didn't work out.

You guys need to setup a 1 gallon jug for a fuel tank and run that inside the car with a valve to switch on the gas tank again. The issue is of course the fuel pump DUH!! which is in the tank so a pressurized tank or second pump is needed or some precise fuel metering gauge. The other problem is the fuel pressure regulator recirculates the over flow fuel back into the gas tank on some cars like the Geo - apparently not my xB.

huh?
did he put WATER in his fuel tank???

I think (sometimes!) if we compare molecular weights here, we're not gonna see much mechanism for even the slightest delta! It all disappears (good or bad) in the "noise" of life! My tailpipe appears to be a little "cleaner", though. What means this subjective observation? Hmmm.... -Ted Hart |
