On your infotainment screen, hit the vehicle button (little icon shaped like a car). Find the trip information page, then a page will open up that shows your MPG. Hit the update button and it should reset your MPG meter

Thank you.

I'm only @ 500 miles, but my cumulative MPG is only 15.3
To misquote Steve Jobs, am I holding it wrong?!?

Love the GX - but it’s an absolute gas pig - I don’t even bother looking at MPG anymore. I’m adding an extended range fuel tank in the fall to solve the range issue.

I got 13.5 mpg while towing a 22 foot 4500 lb travel trailer. This was without any significant grades.

Didn't even know that was an aftermarket option; I'm assuming that eliminates the factory spare? Part of my issue is coming from an Escalade Duramax that never dropped below 24mpg; it had a 640 mile range & that's for the short-wheelbase version with the smaller tank. Apples and oranges, I know...

Also did a trip from Longmont CO to Lincoln Nebraska (not towing). Averaged about 21.5 mpg, mostly 80+ mph interstate driving. Probably would have been better if I had slowed down.

I have the gx550 overtrail and a land cruiser prado diesel...
Average city driving on the Prado here in Panama is 8.1 km/L
The average in the gx550 here in panama is 5.6 km/L..
I have been doing some testing in the recent days...
Best average was 10.2km/L... On a beach drive at 80 kp/h...
The problem with this vehicle is the available tank for use...
An 80L tank that when the range is 0km... We still have 15 liters left...
The previous J150 platform had 87L but when the range is 0km there are 7 liters left in the tank...
