So I filled up on fuel last night and if my calculations are correct I'm getting 16.3 mpg. (City/stop and go driving)

 

Sorry but AWD or not, I'm not thrilled by this mpg, especially from a 4 cylinder vehicle!

 

Here's how I calculated so feel free to correct me if I'm wrong 'cause I suck at math!

 

Trip odometer had 156.7 miles (set from last fill up)

Took 9.6 gallons fuel

Divide 156.7 by 9.6 = 16.322916 mpg :-\

 

Even with the snow we had in Philly this week I'm not thrilled by this figure!

 

Also am wondering about the infamous Subaru fuel gauge, if My fuel tank capacity is 15.9 than 1/4 tank should be 3.975

 

But my gauge read 1/4 full and according to my calcs above I still had 6.3 gallons left (15.9 - 9.6 = 6.3 gallons) which should be noticeably over the 1/4 tank mark, no?

 

Thoughts please,

Thanks all.

There were at least two threads about this in the last week.

As for capacity, the tank will hold 15.9 gallons. When you fill up, there's still empty space in the tank, and if you were to run out of gas, there would still be some in the bottom of the tank.

And the needle hits E when there is still a "reserve" of fuel in the tank. The stuff you are burning while the light is on.

It's very difficult to make anything out of a one time mpg check. Perhaps you didn't fill it up last time...or overfilled it this time. You really need to take a running average over the course of several fill ups...one thing road trips are good for. Then there's driving style...we're you spinning in the snow, evaporation, idle times, etc. Granted sub 17 is pathetic but as a one time thing I would suspect another anomoaly rather than the car.
