hyway with tornado 1.255 gal first click. 78F without, 72F with tornado. Winds N 12 mph, North trip 59mph, south trip 65mph windows down cruisecontrol
No traffic. I know short trip. Don't beat me up too bad 22.94 with 21.73 without
Why the different speeds on the test?

It seems to me like that was a-b and not a-b-a. I remembered compq once did a test like this with short freeway + pump measuring and got some 140 mpg number.

Slower speed on north trip, speed limit lower.

If it was a-b I would not end up at the same place.(gasstation)Where i filled up in the first place.

Different speeds, different temps, different wind conditions. Needs to be round-trip, back to back.

At least it was all highway driving!
I don't think you understand it was round trip back to back. Down the hyway 14.4 miles(65mph) then turn around come back 14.4 miles(59mph) to the same gasstation. Two runs with and with out. Total test took little more than 1 hour. It was little cooler the #2 run with the tornado. Wind was equal on all runs.

Ah, I see now.

By A-B, SVOboy is referring to the items being tested. As in "A" = get a baseline, "B" = test the thing to see if there's any change, "A" remove the thing to see whether you return to baseline or not.

Still, too much variability - particularly the speed difference (my car gets several MPG difference between 59-65, which I've tested). Sorry!

But the to dif. speeds are done"with"............then to dif. speed without. It like the wind against then with the wind. Nullification. The speeds just average 63 mph per run.

I should have went the same speed both directions so nobody here would get comfused.
