Where's my MPG going? - Page 3 - Toyota Yaris Forums

There is no way to be certain of MPG accuracy on a per tank basis, no matter what your methods are. The only way to be somewhat sure of your accuracy is time and quantity. The more tanks you put in, the more statistically accurate your data becomes.

If you always fill up to the first click, then record that data, over time your number will become more accurate.

This is why when you have completely paid for your gas and the pump is turned off, you should re-insert the noozle and give it a squeeze to release the fuel(that you paid for) that was left over in the hose. But it will not go back into the pump.

Does that mean when I get to the pump it is very likely that there is (free) fuel in the hose that I can get in my Yaris........before I pay to get my gasoline? I should empty the hose......then pay for my normal fillup?

Yes....also this is why people complain about some pumps charging customers before they depress the noozle to release gas into their tanks. If the previous customer drained the hose as I mentioned before, some pumps will re-fill the hose the next time someone pays for gas, charging the next customer.

It really varies driver to driver as has been said many times already.
Its cold here (7F with wind and snow) and I dont drive slow, usually speeding up quickly and downshifting hard before lights. and I have been getting 40mpg religiously.

Winter always gives me crappy MPG figures no matter what vehicle i drive,
During the summer i can get 700kms per tank on my 08 sedan or my 01 Echo,Past couple of weeks its been fill up time at around 400kms,i doubt if i could reach 500kms with a full tank these days.

Sure you're not using third gear instead of "D"? That was my problem for quite some time. Little children, do not do what I have done!!!
