I've noticed the lie-o-meter has trended upward with my last couple of tanks. From the normal low to mid 21's, up into 22+.
I love it when that happens.

 

Same here....along with hot weather, I'm back up to my 24-26 average.

 

Been making summer blend here since the end of March.

 

18...

 

I would love to ride in your guys trucks to see just how you get these numbers. Hahah. Must go everywhere downhill Botha ways. I have averaged 13.5 over 20k miles

 

On the flip-side, I would love to see what you do to only manage 13....

 

I've been getting over 20 hand checked for a long time now. My lieometer says 21.2. I have 27000 miles. I have a 30 mile commute 2 lane country roads and another 8 miles city to get to work. I am running 93 octane.

 

I think mine has said 15.9 since i've owned the truck. Haven't believed that meter since it told me i was getting 20 on my 6.4 powerstroke.

 

This past weekend I tried a tank of Non-oxygenated Super Premium. I only was getting 8.5 MPG....

 

What truck, what tunes, what lifts, what tires, what other mods? My last check I was getting 18.4 MPH running at 76 MPH on the interstate. That's with a 2010 FX-4 with the 5.4. Totally stock except for a bed cover. Probably 800 #s in the bed and i have a lead foot.
