58 mpg in my aveo

[AVE0SAM]

see these high mpg are happening when you drive 55mph on highways

So you would believe me if I said I got 78mpg in my Aveo, if I were an admin here and if I said my mother was sitting next to me when it happened?

Ok.

58mpg once doesn't make it a real number. Statistically, you have to repeat it over and over and over....then make an average and CI (confidence interval, 95% would be respectable)

Then we'd know the real mileage you're getting. Get me numbers on 10 fill ups, I'll calculate a good figure for you (average, range(95%))...

Was the car at the same angle when he filled it back up? did he fill the top hose on the first fill and not on the second fill?

Only way to find out the real mpg is with a scan gauge II or if you average it out over a long period to remove all the possible sources of error (as much as possible).

Statistician out.

i imagine it is possible for both daniel and dennis to mess up (ie sometimes bubbles form in the gas tankn and you have shake the car to burp it out) but the fact that they were both doing around the same speed of 55mph (which a favorable speed for mpg) with no traffic on a highway then it is just as likely that it could have happened....yes an average would give you a better idea but not everyday is going to have the same constants like temp, traffic, speed, hills or not....also denis mentioned it was rainy which leads me to believe there was a lower coeffiecent of friction between his tires and the road that once he got up to speed and keep it (which usually happens on highways) it would take less efford for the car to roll

p.s. that last part is just some bs
