Terrible 4 cylinder mpg

No problem. Exaggeration /forgetting makes for much better conversation. Without it, it would be one boring f'n world. This entire web sight is filled with it....thank god. That was an exaggeration on my part .

 

I, too, got less than expected fuel economy on my '13 DC i4 Prerunner. I averaged 21.8 mpg; but I drive 80-90% on the hwy. Now that full size trucks get the same or better mileage, I upgraded to the '15 Ford F-150 2.7L V6 EcoBoost Supercrew Lariat. It's like going from regular tv to UHD TV! The ride is smoother, much quieter, and no annoying steering wheel shake.

The good news for those of you who are still hanging on to your Taco is that the Taco does an excellent job of keeping its value. I bought mine for $23,500 in Sept '13 and put 57,260 miles on it. I still got $19,000 on a trade in for a Ford (while still getting an excellent deal by "TrueCar" standards).

I'm not hating on the Taco; it was a fun little ride for a while...but, the F150 was the way to go for me.

 

I would be afraid I would pop the Hankook tires on my 16 Tacoma putting 45 psi in them. I put the 1st air in mine today and brought them up to 35 psi.

 

Guess you have to ask yourself if another mile per gallon or less is worth wearing the center of your tire prematurely with 10 to 13 more lbs of pressure. You can ruin a decent set of tires with improper inflation and irregular tread wear. Tires especially made for higher pressure like road bicycle tires have raise center ridges to limit the wear on center tread area. Auto tires don't. Not only that, there is little to no gain in going much over recomended pressures except to handle heavier loads. The light foot does much more then over inflation to increase mileage.

My 80,000 of 30+ mpg and even tire wear disagree. I've run 50 psi with great results. One short 2 tank popular mechanics test doesn't qualify.

Most of my miles were below 70 mph though, I agree at 70 the tires pressure don't matter, but on 30-55 roads it makes a big difference.

 

I run my tires at 40psI'm I have since I got them. Being the heavier tire they can handle it not problem and my truck is fat. In 35k km I have not remarked any irregular wear. Most likely because I rotate my tires religiously. I did manage to burn through half a tank of fuel this weekend in like 5 hrs but I was snow wheeling lol

 

The transmission isn't going to make any difference on fuel economy on the highway. Once it has shifted out and and the transmission is in 4th gear overdrive it's final gear ratio with be close to the same as any other manual or automatic. This only applies to level highway driving where the transmission can maintain 4th gear. Around town in city driving more gears will give you and advantage.

You will notice on the highway the auto 2.7 actually gets better mileage than the 2.7 manual 5 speed.

On my 2.7 auto 4WD I return around 21-24 depending on the drivING environment.

 

Yes and no. the old 4-speeds were originally designed in the 80's and are not near as efficient as the 5/6 speeds designed in the new millenium.

 

City mpg yes. Highway no. A tranny shifted out out in overdrive will have close to the same ratio irrelevant of how mamy gears are sitting in the case. Look at it this way. If the engine is running at 2,000 rpm at say 55 mph and has the 4 speed and the the same motor with the 6 speed, same motor at 2,000 rpm at 55mph the number of gears doesn't any bit of difference. This is only true at highway cruising speed.

 

Explain why the old 4runners / tacoma's with a 4 speed auto returned worse MPG than the manual, both city and highway, while still having a lower overdrive. Now, the 5 speed auto has the same lower overdrive, but gets better city and highway mpg.

 

An automatic has a planetary set, pump and torque converter to spin. Granted the torque converter locks up, the pump is constantly running and pushing fluid through the valves. There's a good bit of your loss.

 

Should have got the 4.0 I get 18/22 and I'm lifted 3 inches and run 33 inch tires on 18 inch wheels

 

Should have got the 4cyl, mine cost me a whole lot less than yours and I get 21/24 in my driving. Or should've bought a full size with more power and room and the same mileage. Really what did you expect to accomplish with this comment? Everyone's driving style is different, I see v6's reporting as low as 13 or 15.

 

I've actually found that my truck does best on back roads. I can drop speed going up hills and coast down them, and the rest of the time it's just rolling along just above an idle, with me barely touching the throttle. My highway MPG's are only around 18-20, but if I try on backroads I can usually get 21-23 out of it pretty easily. And that's with the 4.0l

 

Back at ya. Explain why a 2015 Tacoma 2.7 4 speed auto gets better fuel mileage than the same Tacoma with a 5 speed manual?

 

The person driving the 5spd can't drive ?

 

Normally I log onto this forum every few months and never comment, but after reading some comments I felt compelled answer. I also have a 2013 Prerunner DC 2.7, but my mpg are never under 20 mpg. I bought it new and it now has 77K miles. I always fill up (w/87) and the light comes on at 429 miles, which is 21-22mpg. I wanted the 4 cylinder because of the better mpg as I have an 85 mile daily commute. My last truck was a 4 cylinder Frontier that got equal mpg. The Tacoma is bigger and has more power. I live in San Diego and my commute has a lot of rolling hills. Best I ever got was 27 mpg on a trip down in baja. While my highway speed is 75-80, I drive extremely conservatively (coasting, decreasing speed up hills, etc.). Additionally I have towed with it multiple times and it does fine. Even towed a 3500 pound trailer on a 2500 mile trip. I really like the truck and find no need for a 6 cylinder. It is limited, but that is kind of my style.

 

I have a friend who works as a Ford Tech. You couldn't give him one. In the automotive repair industry we refer to them as "eco boom". Wait till you have to replace one of your turbos, $, and there known to go.

And as far as gas milege, read this. http://truckyeah.jalopnik.com/the-ford-f-150-ecoboost-engine-actually-kinda-sucks-sa-1678282081

Hope you stay happy with your Ford.

Back to our regularly scheduled program.

 

It doesn't, says the EPA:

Boomshakalaka.

 

Is your truck the double cab? That's the reason if it is. All the added weight of the double cab means the engine has to work harder resulting in less mpgs.

Edit: Nevermine, someone already stated this.
