Toyota Tacoma "Real World" Gas Mileage

Today I got 22mpg all highway for 120 miles doing 80 down the highway without cruise and no wind at all. On the return trip, I used cruise at the same speed and there was a headwind but my fuel gauge didn't seem to move any more than it had on the trip up. I will go top it off shortly and post the results later. This truck continues to amaze me, matches the same mileage I had with my 4 cylinder and sometimes beats it. All I did was change the oil and air filter and that made a huge difference. I definitely can't complain about my mileage on the highway with my V6. I was always under the impression that the 4.0 was supposed to get better mileage but I think my 3.4 edges it out a little based on the results I've seen posted here.

 

Hey, thanks for the tip.

So I had another MPG test this morning. I intentionally drove this last tank much more "spirited" (not so eco friendly).

Here are the calculations (No adjustment factor, your suggested adjustment logic, and another suggestion on the logic)

No Logic:
Trip @ 358 Miles / topped off @ 19 gallons = 18.8 MPG

Your Logic suggestion:
Trip @ 358 * 1.04 = 372 / 19 = 19.6 MPG

Another suggestion on the logic:
265 / 70 = 265 wide and a sidewall height of (265 * .70) or 185.5
265 / 75 = 265 wide and a sidewall height of (265 * .75) or 198.75
The percentage difference in tire diameter is 1-(185.5/198.75) or 6.6%
Trip @ 358 * 1.066 = 381 / 19 = 20.0 MPG

I'll take any one of them as great!

 

2009 V6 auto Prerunner 68,000 miles.
I purchased it in May and check my mileage every tank.
I have never been below 20 mpg and never above 23. Most of my driving is 60 miles round trip to work (no interstate) traveling between 45 - 60 mph which is optimal for the gas mileage. I am pleased with my Taco so far.

 

I have a 2014 Access Cab V6, 4x4, 6-speed manual. I average 18.3 with the best being 22.6 once according to my Fuelly app. I would stay it is 50/50 highway city usually.

 

I've had 2 2011 4.0 pre runners....one for about 50,000 miles and one for about 4,000 miles now. Both are consistently right around 21.0 mpg. I drive at least 80 miles round trip to work per day and most of my miles are highway.

 

48k on my 2013 DC OR 4x4 V6 auto, truck is stock.
Avg 20.2 on my most recent road trip mostly 2 lane highway, very little city.
Usually my avg for a week is about 18 mpg.
I use 87 fwiw.

 

There's highway and then there's "highway" - ie the difference between 55mph and 75mph could easily be 3-5 mpg.

 

I average 65-70mph with 265/70/17 Cooper Adventurer tires.

 

My 2009 6sp with P245/75-16 Michelin LTX MS2's "sweet spot" is about 67-68 mph (per ScanGauge) and gives me about 21 mpg on rolling hills on the interstate. Lost about 1 mpg with the Michelins, even though OEM size, the Michelins are .4 inch wider tread.

 

2006 DCSB TRD OR 6SPD. My mpg has been falling and I'm down to about 11.8mpg avg. This last tank just got me 200miles. What gives?

 

Enjoying that 6spd are ya? Right foot gets excited? Actually I have to try hard to get under 12 and I'm running the SC.

 

I might have to change my speeding addiction to an addiction to speed and other drugs.. might be cheaper.

 

Just came back from an 800 highway miles trip... No cargo, just big old me and my bag for 3 days... 16.5-17.5 mpg... add 1/2 mpg for the odometer error due to the 265/75 tires. Drove 5 mph over the posted speeds, tops.

 

you must be real fat or the posted speeds are 90 mph. I get 20-21 @ 70 mph

 

Still getting about 17.5 to 18 mpgs. It dropped about 1 mpg with the winter fuel. Before the changes it was 21-22 mpg.

 

-my lifted, 2012, AC, 6spd, v6, on AT3s gets 20mpg on the highway at 65mph. anything more and it drinks fuel.
-towing the boat at 60mph I get around 15-16
-city mph 14-15

 

How do i adjust for the 275 70's?

 

2013 PreRunner Double cab driving all city keeping rpm's under 2000. Gas light comes on around 270. I filled up at 297 miles with 18.490 gallons. Meaning I am only getting 16.06 mpg? Seems really low considering my eco driving. Granted I hit a light every 1/4 mile or so, i was still hoping for better figures. Does this seem right?

 

2011 Double Cab 4x4 Longbox Automatic 4.0 V6 on stock 245/75/16 dunlops and original steel rims and have traveled 74,683 km (This is Odometer reading, with a GPS measurement factor, there actually is about 400km less but ignored for calculation purposes as it changes fuel consumption by about 0.1mpg) and have put in 9111.101 L in fuel for an average gas mileage rate of 12.2L/100km or 19.3mpg. Best mileage on any fill up I got was 22.3mpg and worst was 15.2mpg.

Total spent on fuel is $9,478.69 Canadian so works out to cost $0.127 per km driven for fuel. At Canadian fuel rates over the past 4.5 years which based on these numbers average $1.040/L (Canadian Dollars) or about $3.13/gallon US Dollars at todays exchnage rate.

About to put on 265/75/16 Duratracs on this weekend so we will see what that does to mileage over next few years.

 

I'll do a test on my next fill. I remember testing 6 months ago and got around 20-21 MPG. I do a fair bit of highway, and use the eggshell mod as well as sticking with the speed limit on the highway. Those two things make a massive difference, like an extra 80 miles to a tank.
