Try this:

1. Find a flat road with no traffic.

2. Accelerate to 45 mph.

3. Reset the MPG indicator.

4. Continue at 45 mph, using the least amount of gas pedal pressure necessary to maintain that speed.

I did this for about 1/2 mile; my MPG indicator exceed 20!

Drive 45 mph? Are you serious?:)

Will 20 mpg sustain if you continue, or is this a short-term phenomenon?

I have no idea......for the purpose of scientific experiment I was willing to do this for a half mile......but this is a JEEP SRT8! To drive it further than a half mile at 45 mph would be a crime!!!! LOL.

It didn't actually start as an experiment - I was on my way home from getting gas, going slightly downhill, reset the MPG and it moved up to 29! I was like WOW. So when the road became flat, I reset it again.

The lowest I had mine was 7mpg:D
