My car isn’t even a year old yet and the thing has been lying to me.  I first caught noticed something was up about 6 months ago, but I decided to let it slide.  After a while, I couldn’t take it anymore.  I took out my camera phone and got photographic evidence.  See if you can identify the problem:

Did you catch it?  Well, yes, there’s the obvious fact that I’m not good at taking pictures and my camera phone is crappy.  But look at the gas gage and then look at the bottom mileage number.

If you do the math (and I’m sure that you already have) here’s the mileage I get per 1/4 tank:

  • 1st 1/4 tank - 181.4 miles
  • 2nd 1/4 tank - 132.8 miles
  • 3rd 1/4 tank - 139.1 miles
  • 4th 1/4 tank -  91.9 miles

So, on the first 1/4 of a tank of gas, I’m really, really efficient.  On the last 1/4, I burn gas like there’s no tomorrow.  I heard from a friend who rented a Nissan Maxima, and he noticed the same thing.  So, if we assume that I drove consistently throughout the tank of gas (and you can trust me because I have a blog), we’re left with two possible solutions.  (1) The 2008 (maybe earlier, too?) Nissan Maxima and Altima gas gages aren’t very well calibrated.  In fact, they’re way off.  The first 1/4 is actually more than 1/3.  (2) My car is just much more efficient when it’s belly is full.

I don’t know which is more believable at this time.  If it weren’t for the fact that I’m in the middle of my 11th free month of XM radio, then I might take the car in to get checked out.  I’d rather have the free radio than the fixed gage.  If the “free 3 month trial subscription” ever ends, though…
