Mpg issue

Hi guys. I have a 2023 trd OF stock wheels, tires, and suspension but am getting 14 mpg according to my dash. Any ideas why it may be so low? Thank you!

 

probably drove a short distance let me guess 5 miles?

 

Do it old school and count your miles per gallon from fill up. Dash isn’t always right

Are you running highway,back roads,off roads? What’s your average RPM’s?

 

all city amirite?

 

Thats a rock…

 

We would need more info like how long is this 14mpg average in regards too…10 miles, a tank, a month of driving? Also the type of driving you’re doing like city vs. highway.

 

@Blak Shinobi nope been like that last few tanks. City and highway

 

@Kbar city and highway. Pavement only

 

ok we need a pic of your truck , for research purposes

 

@Road_Warrior city and highway only pavement. Been like that last couple tanks so no not just like a five mile ride

 

By OF tires you mean A/T?

 

@Blak Shinobi goodyear wrangler

 

Are you an aggressive driver? That’s definitely really low. That computer also isn’t the most accurate from what I read. You might want to try a few tanks and calculate the mpg’s yourself the old school way by just keeping track of miles driven. I get better MPGs than that on my mud tires.

 

@Road_Warrior yah probably a good idea. Thank you for helping.

 

Anytime! For reference, I get about 18mpg average city driving. I’m on 265/75/16 mud tires with a bed cap. Highway miles are around 20-21mpg. Every truck will be different though. Oh and my truck is tuned.

 

@Thatbassguy it seems it’s getting worse everytime I fill up a new tank. I am not an aggressive driver I try to stay below 2 rpm. City/highway combined, live in Tucson AZ. No roof rack or bed cover

 

@Road_Warrior yah I was hoping more around 18. Getting oil changed under warranty next coming weeks I’ll ask them about it. I would like to get mine tuned but nervous it would void warranty

 

yeah i get 18 city and 21 highway. mine is truly stock , either you have really beefy tires or something is not adding up

 

If it's getting worse for no apparent reason, it could warrant a trip to the dealership. Generally, it seems like people's fuel economy generally get a little better after a few thousand miles, if anything.
