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.
I'm going to say no positive results also maybe even a slight decrease. His metro is already efficient. It seemed that those with FE measuring equipment saw no increase with the magical juice when tested.
Mark cancelled the test. Running the car out of gas proved problematic, and inconsistent:
I had many kilometers of low-no power driving. It kept going by feathering the throttle, but if I asked for more it started to fade. I was worried about the fuel pump over-running and eventually destroying itself - especially after 12+ run-dry experiments. Plus, the car kept restarting every time it supposedly ran out and ran down once again.
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.
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?
Acetone in the gas? I assume this is the ratio often bandied about...~2 fluid oz per 10 gallons? Me? I use the stuff...& I don't see / feel much difference, but then again...not much of anything is not gonna make much difference! LOL !
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
