What is the best MPG you have ever had?

Q...does high altitude lower octane gas help/hurt mpg?

 

You mean 17 on the city?? Lol

 

Over the course of a 3 hour drive I hit 24 when it was all stock. Same drive now gets me 21-22 with bigger tires, tent and softopper.

 

What tire size?

 

Up to a 75 series on my OR. 265/75r16

 

Gotcha!

I was planning on 255/85/16.

 

Same here with the 2.7, I drove from Pennsylvania to Arizona and split up the drive to about a tank a day's worth to sightsee...

Day 1 24.0
Day 2 26.7
Day 3 24.5
Day 4 25.6

Then I met my friend in Oklahoma City and traded off driving...

19.5 because he's impatient AF and has a lead foot.

 

Only into this about 1500 miles. 2017 ( weren't we just writing 1965 on our papers a little while ago ?)
6 cyl TRD 4X4 gave me 20.9 mpg at today's fill up with a calculator. Hoping for better as this thing loosens up.

 

Weak. Mine says 9999mpg downhill

 

I don't think that math is correct considering a gasoline engine roughly use 1/2 gallon per hour to run. So a 21 gallon tank can only idle for 48 hours and I think it would take a lot longer than that to accumulate 9999 miles.

 

You must have the 4 cylinder

 

Scanguage said it so it must be true

 

Usually around 24 mpg
