Don't you have chevron over there????

I've seen one chevron ever, in kansas I think.

I've seen them in Kansas too but I didn't have to click my high heels to get there.

To start, I did as JanGeo suggested...I ran a warmup run 50ml of Shell fuel. And I took aproximately 15 minutes between runs to start the next.

The constants in this round are:
-Three 200ml runs
-Barometric Pressure remained constant at 29.42in
-No measurable windspeed

Run #1
-Length: 20:49.00 minutes
-Temp remained within 36°F
-Humidity was 39 to 40%

Run #2
-Length: 20:25.00 minutes
-Temp remained within 35°F
-Humidity: 40%

Run #3
-Length: 21:09.00 minutes
-Temp remained within 34°F
-Humidity: 42%

P.S.~There are no Chevrons around here...
And damn I was waaay off in estimating how long 200ml would run! lol

well this blows. Some of use can't really use this because we have different gas stations. I only use Chevron and shell because all the mechanics we've been to recommend it.

The solution is to do it yourself. The more data we get the better, IMO. Some of the data will overlap and some will not. in the end we'll have a great set of data.

I might have to try to find an old lawn mower for this very purpose.

Nortonpro, are you emptying the gas tank between each run? I'm very impressed with the consistancy of the first three runs on the same gas.

I don't own a lawnmover and doing this experiment on a car will produce different results due to driving conditions, other drivers, weather and etc.

Yes, gravity clears the whole fuel line and stalls the mower out for the next run. All the way down to the last drop of fuel.

And there were many constants during this round. I may have to get a normal measuring cup to truly measure 200ml out on a perfectly level surface, rather than this funnel to get any closer consistancy.

There are no leaks and with no wind this round, no measurable evaporation.

apparently it increases performance like nitro and produces some nasty acids in the motor that will distroy it.

results of test look good - you will find that if several people do the same test who has the best lawnmower! LOL! Anyone want to ship you some other brands of gas to test?
