Serious good mpg

Hi all, I made a trip from GJ CO to Mancos CO this past Sunday. I went through the Telluride CO route there and back. On the way back just past Ridgeway I checked the mpg and it said 30.4 mpg. Wth! that is unreal mileage but it's true. Thought the truck software was false but today it is recording the same expected mpg around town.

 

Doesn’t mean much if you aren’t filling up over 400 miles.

Our Subaru will sometime say 99mpgs doesn’t mean much.

 

explain please? I Left with 3/4 tank added 5 gallons in Mancos and returned with 1/4 tank left. Each way was 199 miles and in the Mancos area drove around 10 miles.

 

per trip mpg can vary a lot depending on the road/elevation/etc. but if you can get 400 miles out of a tank of gas then you are doing well for mpg or look at overall average for the whole tank.

 

These trucks have a general range of 385 miles per tank and can be pushed slightly further. Getting 30.5mpg doesn’t mean much if you are still filling up at around 385-400.

If you come back and say you drove 500 miles on a tank then we can talk.

 

I’m skeptical you are truly getting 30 mpg over the long haul. Keep driving and check back.

 

Is this a 4 or 6 cyl? If it's a 4 cyl, That doesn't surprise me at all. On 'summer blend' I can easily get 28 mpg from my 2.7 all day long... I just drive the speed limit on cruise. Rarely have to put my foot into it unless I have to pass a logging truck or 'Mom n' Pop Winnebago' ...

 

6 cyl

 

I get 30mpg coasting down hill.

 

X2

And when going off a cliff

 

well I had a great tailwind..

 

How did you calculate the mpg?

 

the truck did

 

do the math at the pump before you celebrate.

 

I went a few time over 400 miles on the tank and best mpg I saw was 24.5 (squeezed 465 miles of the tank).
Average mpg on 400+miles tanks was 22.5.

 

One data point in a long time line. Let me know after a hundred full ups. It will be between 18-20 mpg guaranteed. Have fun with it!

 

Per tank or per trip?
Real MPG of any value is miles driven between the last fill-up and the current fill-up, divided by the number of gallons it took in the current fill-up.
Anything else is meaningless unless you're watching it to tailor your driving style to ideal fuel economy.
This is my REAL fuel mileage to date on my '21 TRD OR AC V6 auto:

 

I only get good mpg when i use the cruise control. Otherwise i average around 12 to 14

 

I drove .1 mile today and got 9.7 mpg

 

Nailed it...
