Tacoma Gas Capacity Issue

Hello Friends I need clarification,
When I had my taco brand new, on a full tank she would show about 400 miles till empty. But after 2 years. With 28k on her now Whenever I fill up my tank all the way, The miles till empty shes showing is now been showing under 350. Can someone please explain why I’m filling the same amount of gas but I’m getting less miles out of it? Thank you so much for your time

 

Driving style/habits.

The built in system figures your average MPG and calculates roughly how many miles you have left.

When the vehicle was brand new, there were too few miles to figure an average hence why you saw something that wasn't accurate at all.

Your mpg can also change from one fill up to the next; maybe you were late going somewhere and/or getting back so you averaged even less than the week after since you were speeding or something.

 

No idea where to start with this one.

 

Oh shit it's Friday; I replied as if it were Thursday

 

Switch the rear diff oil to synthetic, maybe

 

Do you know how many miles you are actually getting per tank? That miles to empty is just an estimate. If you coast downhill for 100 miles, it will stay at 350 for a long time.

All that weight up front

 

How is this not obvious?

Rockwell solved this years ago

Enjoy, I filled 18.7 today and the sled said 329 MTE. This is about the sixth fill up since my free tank full Toyota provided when I took it with 6 miles on the ODO.

If you lift your truck or your girlfriend gains 100lbs, you gotta install a a flux capacitor on the voltage supply of the fuel gauge.

 

Thank you so much for your help. I appreciate it

 

When I fill up to full, mine will say "250" at the most. I average 19-20 MPG

I have no idea why, but it doesnt really bother me since I know the numbers are inaccurate anyway

 

Don't trust those numbers. When I got my new 2018 Tacoma, I'd fill it and the computer would say 350 miles to empty and I'd get 15-16 mpg mixed city/highway. Then it would drop to 270 miles to empty. After 2 years and 21,000 miles, it says 320 miles and I'm getting 18-19 mpg.

 

After 1/2 tank start looking for a gas station because it drops suddenly after 1/2 of a tank. That is about all I know for sure.

 

It's a good rough estimate. It isn't supposed to be exact.

 

Mine after fill up is consistently at 257. It might be because I’m in 4x4 for about 6 hours of my work day every day.

 

I use the mileage tracker app to keep a record on every fill up, it does it’s calculation using math so it eliminates the computer guessing. After almost 2 years on my 19 2wd sport it’s getting a lifetime average of 20.7 MPG according to the math. 20.7 avg MPG multiplied by 18.7 (I think it is?) fuel capacity is 387 miles. After fill up the DTE is usually somewhere in the 370s so it’s decently close (leaning toward safety) based on your history.

 

Posts like this make me despise working at the dealership..

 

Vehicles never get the mileage claimed, funny how that works.

 

Mine always says 385. Always.

I get 16-18mpg depending how bad traffic is the three days I go between fill ups.
