There was a major change in how FE was measured a few years ago starting with the 2008 Models with the intent of making the sticker number more in line with the real world.

The new test accounts for higher speed, harder acceleraton and cold temps.

So your older vehicle was rated using a different more forgiving test than the new model.

Good morning all,

New proud owner of a 2013 2SS 1LE. The first thing I noticed it's how fast it burns gas compared to my old Nissan Maxima. It's a downside but nothing beats the sound of the engine and the big smile in my face.

I agree we should have more efficient engines but How about reducing the gas prices instead? what is happening right now is criminal if you ask me. We can go back to $1 gallon if we really want to fix the problem.

Step 1) Invent cheap space travel

Step 3) Gas now costs 10 cents a gallon.
