I usually get about 300 miles on a tank in town - suburbs/hills and alot of stop signs- first trip on interstate and I made it 250 miles on a half tank!! Now if I can figure out how to do better in the burbs....

wow. I like the highway mileage but do you have a lead foot around town? Figure 17 gallons on the fill-up and your only at 17-18 miles to the gallon.

In mine I average about 470 miles to the tank at about 17miles or so fillup. I try to track it but I get an average of 26-27. Most of my driving is highway, but 40% or so is side roads. I do notice, and I might be making a wrong correlation here, but when I change brands I get better milage. I bounce back between Exxon Shell and Irving. I refuse to buy gas from no-name companies.

The VQ engines are capable of pretty good has mileage on the highway. My G gets about 29 between 65-70, when I use the cruise control.

On the daily commute the average mpg is between 22-24.

'Per tank' is not a meaningful way to measure fuel mileage. There are far too many dozens of variables involved. Push the tiny **** on the right side of the speedometer display to set either the 'A' or 'B' mileage tab to zero when you fill up. Then, next time you fill up, divide the miles on the mileage tab by the number of gallons required to fill up. That gives a good indicator of your fuel mileage.

The 'per tank' method is essentially meaningless because the fuel gauge is not truly exact on any car. On five 7th gen Maximas sitting side by side, if you filled each up as soon as the fuel light came on, each one would require a different anount of fuel to be full. This can vary by several gallons.

When the fuel light comes on, there are from two to five gallons of fuel still in the tank, depending on the guage on the Maxima you happen to be in. But we are not supposed to use those last few gallons, because the fuel pump is in the tank, and it is supposed to stay immersed in gasoline in order to prevent overheating. Also, running out of gas in this Maxima can cause problems, even to the extent of messing up the catalytic converter, which will cost from $390 to $900 to replace.

I have figured it out for the last 4 tanks and they have all been about the same- 287-310 miles per tank- driving to work and running around town.. today i'll be returning home on interstate so I'll have much better mileage= thanks for this info but I already know how to figure it ,,

Ethanol.

The more ethanol, the lower your MPG.

Thank the EPA.
