Difference between Sport and OR fuel tank?

Hey guys, my brother owns a 2016 Tacoma 4door 4WD Sport, and I have a 2021 4door 4WD off road.

When he fills his gas tank up to full, he’s getting like 620km’s till empty, where as I get like 464 on a full tank till empty…

I thought we both have 21.1 gallon fuel tanks…why such a stark difference in our two readings?

 

Depends on what gas mileage y’all have been getting and that depends on the amount of stop-and-go traffic y'all have been doing, driving habits, etc.

 

Same tank. It could be down to tires, air pressure in the tires, weight of the wheels and any other weight you carry. It probably has more to do with driving style and distance and distance of your average drive compared to his

 

Lots of potential reasons:

• Driving style
• The Sport has the much maligned front air dam which routes air around the front of the truck instead of allowing it to roil around underneath
• Tires; the Sport has smoother road tires compared to the tires on the Off Road
• Transmission? Do they have the same transmission or is one an automatic and one a manual?

As kind of a benchmark, I have a 2022 TRD Sport 6MT and routinely get 675-700km out of a tank when I'm on a road trip.

 

Sport has a scooped tank

 

Also if the 2016 and 2021 are both Auto do you both drive with ECT on or off?

 

464km's is 289 miles. That's about all I can get in mixed city/highway driving on my 2016 OR (~18mpg) on 3/4 of a tank of gas. I get about 22mpg highway which is about 560kms. Are you sure that isn't the difference? My in-city mileage can be 14-15mpgs in the winter which is only 370km's on 3/4 of a tank.

 

The Tacoma's Prognosticator of Future Emptiness has always been wonky and complex. Much more so than other cars. This one puts a lot of weight on individual driving habits.

 

Make life easier - use the other gauge in your dash (lower right corner) and forget about Distance To Empty.

 

How many miles or kilometers you get to empty is useless information. Way too many variables. You both need to do the math and manually calculate miles/gallon or kilometers/liter. The readout on the dash is rarely accurate. Sometimes very close, and sometimes wildly inaccurate.

Don't trust that number until you can consistently get the same numbers when manually calculating it. Then you have some useful information to make decisions on. And you need to do an average on at least 4-5 fill-ups to be accurate. Depending on road and driving conditions I've gotten 22 mpg and 16 mpg on the same day in the same truck.

Tires, and air pressure in tires can make 2-3 mpg difference on the same truck. It's common to lose that much fuel mileage when you buy new tires depending on what you buy. Unless your brother and you have the same tires it isn't a fair comparison.

 

Winner!

 

Same!

 

And the Skewp gets you...lol!

 

Pretty sure they're identical aside from the OR and Pro having a plastic "skid plate" mounted underneath them. Assuming both are stock It likely comes down to driving habits and differences in commute.

 

The "skid plate" on my Sport is metal and mounts right behind the plastic air dam.

 

I'm referring to the underside of the fuel tank.

 

I think the only difference is the driving habits, all tacomas models eat gas as fuck
