gas mileage for 4.6

[slowyota]

I've got the 5.7 with a 3" lift and 34" tires. Which creates about a 5% difference in mileage. Using the computer I get 13.5 around the city (14.1 corrected) and on a hunting trip this past weekend the computer showed 14.8 (15.5 corrected).

For as big of a truck as it is and the power this motor has I think the gas mileage is awesome.

I've looked over at the f150 forum when the ecoboost came out because I was interested. They aren't getting any better fuel mileage. In some instances it's worse. But that's probably more to do with driver than truck.

I get around 16-17 mpg for a combo of city/highway driving with my '03 4.6l tundra 4x4.

I do about 75% city with many short trips and get 16.7 mpg from April to october. It gets damn cold here and they winter blend the gas from Nov-March. When that happens my mileage is about 2 mpg lower at 14.8. I am a contractor though and always have weight in the truck, as well as 300-350 pounds of truck cap on the box at all times.

I did get 19.9 mpg (11.85L/100) on a camping trip this past summer for the full tank with 85% hwy. That's what the first 2.75 years have given me with this truck. My cousin has an EB motor fard and said it always gets 15.5mpg (15L/100km) in the summer. Needless to say, I'm happy with mine.

Hi all,

I have been averaging around 18 miles to the gallon...or 12.7 L/100 km over the past 17 000 km on my 2012 DC 4.6. For the most part my truck has been averaging as good as my friends ecoboost. During the summer I have seen it hit a little over 20 miles to the gallon... not bad for a large pickup.

Cheers,

Since the originator of this thread was curious about the 5.7L, I'll throw in my 2 cents worth. I have a 2010 double cab with a 5.7 L
I get 14 plus mpg with strictly in town driving and if I'm real careful I can squeeze 15+. Highway runs from 18 to 20 mpg on average
terrain. On one trip from Fairbanks to Anchorage with some city driving in Anchorage for several days I put on 740 miles. Worked
out to 19.2 mpg for the total miles. On the highway I held it at 60 mph for the most part. Nice rig to drive and pretty satisfied with
it in all respects. No canopy, I have the Roll-N-Lock tonneau cover instead. Only other "foreign" add on is a Hellwig rear sway bar.
Tires are Michelin LTX, M/S, P275/65/R18.

Ok, just filled up my DC 2011 4.6 4x4 and I got 14.3 mpg. That was driving the way I wanted, not babying it, but not totally lead footing it either. I filled with 91oct and will drive nicely and see what I get. The winter blend is gonna mess it up a bit.

Ima assuming that the chaps getting 16-18 around town are 4x2's?

Thanks for input. I think the 5.7 is the better buy because from what i read the mpgs are pretty close,so why not get the bigger engine!

[Atomic Ed]

Just use the EPA numbers for comparisons. It's the most controlled testing around. For a 2wd, the 4.6 will get you 2 mpg better than the 5.7 on the highway and 1 mpg better in town, with everything else the same.

all depends on how many miles you are going to put on it. If I had known that I would get a 1989 Honda to drive to work back when I bought my truck I would have gotten the 5.7, but I bought the 4.6 because I was looking at how much money I would save with a one way drive to work of 50 miles, which added up pretty fast for me.

I'll probably take it in the shorts from the non believers, but here goes anyway. I have a 2012 DC Tundra grade 2wd 4.6. I got it last February and now have about 8000 miles on the odo. For day to day use I've never got less than 19.3 mpg hand figured. My best tank was 23.7. The only tanks less than than 19 mpg have been when towing our 18' 3500lb. travel trailer. Those have ranged from 10.5 to 14.1 mpg. I was going to buy a new 4.0 Prerunner to replace my '06, but got a good deal on the Tundra instead. I was worried about having to spend more on gas going back to a full sized p/u, but the mileage with the 4.6 beats my Prerunner's by about 2 mpg.

I've hand figured the mileage for each fillup for everything I've ever owned. The caveats for my mpg figures are that I do very little stop and go driving, I'm old and drive the speed limit, and spend a lot of time between 50 and 60 mph. For the little stop and go driving that I do, my ScanGauge indicates that I would probably get around 14 to 16 mpg, but I'll never drive enough short trip stuff to be able to hand figure a tank.

I believe you...if you stayed around 55 I think that is very realistic, however most people driving around 55 is not.

Ditto, I'm a believer, too.

I used to drive a 2011 DC 5.7 4x2, but now drive a 2012 DC 5.7 4x2. I got/get similar mileage as you with both trucks (both stock, no mods). Towed 5000 lbs. (small 3300 lb. toy hauler with 1700 lbs. of gear) cross country this summer (2500 miles) and got 13-14 mpg's driving at 55 mph (all freeway and included several hundred miles of mountainous terrain in the SW). On level terrain, no wind, empty, driving 65 mph I get 21 mpg, 55 mph 23 mpg, 75 mph 18-19 mpg. Around town (stop and go, speeds less than 50 mph, rpm's 2k and below) 13-15 mpg. Combined city and highway 17-18 mpg. All stats hand-calculated; however, I've found my Drive Monitor Switch (DMS) AVG MPG display to be fairly accurate--usually within a few tenths of my hand calculation. Obviously I have to drive *very* conservatively to get these figures. Let the rpm's get over 2k for any reason and the mpg's begin to drop significantly. Using the DMS in INST MPG mode has really helped me adjust my driving style to maximize mpg's.

FWIW, if I drove a DC 4.6 4x2 under the same conservative conditions, I'm assuming the above results (with the exception of towing) would be 1-2 mpg higher. IMO, due to the higher and broader torque curve of the 5.7, I believe the 5.7 would get slightly better mileage than the 4.6 towing the same load under the same conditions. I towed the above toy hauler (same load and route) with my V6, 6-speed manual, 4.0 liter, Nissan Frontier (261 hp, 281 ft. lbs. torque) and only got 12-13 mpg (vs. 13-14 mpg with my 5.7).

Methinks 4x4 vs 4x2 is making the biggest difference in these numbers people are getting. I Have a 4x4 DC, and the last tank I drove like a 85 year old paralyzed nun (no offense to any 85 year old paralyzed nuns out there), and I still only got 16mpg on 87 oct Costco winter gas. The tank before that I filled with 91oct, and drove the same and no difference in mpg's. The tank before that with 87 oct I drove normally and got 14.

The only mod I made was to remove the charcoal pre filter, and i saw my mileage drop after that. But I believe that the transition to winter gas probably had something to do with it as well. I still haven't been able to get out on the road and burna whole tank at 65mph to see what it gets on the open highway. I have the base model, so no MPG meter, i was thinking of getting one of these-

My 2008 5.7L double cab gets and average of 19.2 according to my scan gauge. My driving is usually 70/30 highway to city. Most of my highway driving is interstate at 65-70 mph. I have got as much as 24 mpg on a single trip if traffic is not bad. But keep in mind my truck is a 2wd without the tow package and stock size tires.

2013 Rock Warrior 5.7liter, 13 city/15 hwy. at 75mph, 33" tires on 20 inch rims, 4" lift. Have 1900 miles on the truck and not sure if it will get any better with age. Probably not.
