How are you guys getting 20+ MPG V6 4x4s

My 07 I drove from Riverside to Vegas and got 27mpg. Same truck, different setup I got 12,5mpg. Waaaay too many scenarios and driving habbits to get a consistent #

 

I'm lookin at the opposite. Yea, there are some re-programming things that happened. BUt pretty sure that was for the stupid "out of control toyota" fiasco.

They had the same sticker, and I'm pretty sure they changed the sticker rating at or before 2005. Regardless truck trend said 4wd gets 18-22 in 2005.

the 1gr-fe has not gotten any mechanical updates I can find.

In other news..


Anyone been able to prove whether or not this truck has a DFCO program? My little bluetooth thinginy (klx?) says no. But I think its doing most of its calculations with GPS and vehicle weight. I know the gauge can be wildly inaccurate. (apparently I get 28mpg If I don't do the math at fill up).

And watch those hypermiler guys. Some of them will do stuff that's downright stupid for a theoretical .02% efficiency gain.

 

If you mean the EPA numbers and the revised testing methods, it changed for the 2008 model year. Older EPA mpg sticker numbers will be higher than 2008+ numbers.

 

My 2010 TRD Sport Long bed 4x4 with 15K miles, all Stock!
I have been getting 18mpg. I drive 70% HWY , average speed 70mph! When I feel like playing some, I get much worst MPG, but never better.
I have not done any travelling with my truck yet, so not sure what would do when 100% HWY, but I don't supposed it would be much better than 19mpg.

 

Try 65. I'll bet you gain 2+mpg

 

Yea, if you don't want to be the guy that slows down the insane drivers that think they're in a hurry, you got to take a hit on the mileage, no matter what you drive. Its either that or well, whatever the consequences of driving 55-60 in a 70 zone are. Keep right I would wager. I've done it driving cross country (in a tacoma) but not when I was in busy areas.

The 55 speed limit that was "passed", pressed in the 70s was not due to highway safety (though I'm sure it played some part) it was due to the oil crisis. Then when that memory faded, cars got "safer" people got all about increasing speed limits so they could make up valuable seconds going places they didn't need to be in the first place.

(1/2 m*v^2 is still a good reason to slow down for safety's sake, I use kinetic energy? is that right for impact energy? I think so, but I've never worked for a crash lab, regardless it is the same equation that makes your mileage suck when you're trying to go fast.)

I went to Eugene from SoCal in a 2009 DC 4x4 6spd and had 4 passangers total and about maybe 300-500lb in the bed and got about 20-21 miles per gallon getting over 400 miles per 18.5 or so gallons. Average speed was about 67mph.

 

I'll be making a 3.5 hour trip Friday. I'll figure MPG out then.

 

on the freeway with intake,exhaust throttlebody spacer,hedders and chip with 33's doing 55 i got 21.48mpg after including the the tire ratio size diffence...it is possible...but 65 and below 18-19.8 is decent its how u drive u save $$ and spend more time or spend more and save time..u call

 

... ^^^ ... What he said. I can get right at 25 mpg on a flat, rural 2 lane road in south GA at 55 mph with egg under foot (with no wind at all).

Did this last fall (cool dry evening air) with 15,000 miles my truck with synthetic lubricants in engine & (92 or 93 Octane). Yes it is possible to get 25 mpg on a 4x2 TRD with a V-6 and an auto.

PS ... With Michelin LTX AT2s at 36 PSI, front & rear. Everything counts when you want that last 2 or 3 MPGs out of a gallon,

i also try to find fuel with no "corn juice" in it ... but now it is almost impossible. Can get it at boat marinas and small airports for sure ... "no corn" gas there.

 

Got 24+ mpg on the way home from Mammoth today. Quite happy with that number.

 

Is it safe or is there any benefit to running non-ethanol 100% 90 octane gasoline in a V6? it's about .40 cents more near more

 

Safe? Absolutely, real engines were designed to run on it. Beneficial? Absolutely, because more energy is stored in pure gas, however I am not sure of the rough/exact math behind the mileage so I cannot say whether $0.40 is justified or not. Maybe solely for political reasons...

 

40 cents is Absolutely justified. You're paying more in tax for the health care of everyone inhaling the extra dirty exhaust, AND you're getting more energy.
If gas is over 4 dollars a gallon.. maybe $6-7 or so, and you can get 100% (well non ethanol gas) for 40 cents more, you will see a benefit in cash based on mpg. Below that, you may lose an mpg .. maybe 1.5 tops.. but make out money wise.
You lose at most 3.5% of the energy, so you'll have to check the above math. Probably more like 5.50 a gallon before its worth 40 cents? I'm not going to work it out.. i may be wildly off. But that doesn't all translate into 3.5% power and mpg loss. It might be more, probably less.

 

Since I've been trying to get good fuel mileage it's been over 20mpg. It was costing me over $200/month just in fuel.

I drive the speed limit, somewhere between 30 and 60 mph. I coast when I can, I'm usually in 6th gear around 30mph if it's level or down hill. My tires are at 44psi and I installed a block heater. My last two tanks of fuel have been over 21mpg; that includes some 4wd (hi & low range;lot of snow in the northeast) and most temps well below freezing including a couple of morning below 0 deg F.

Most of my driving is to and from work, 52 miles round trip. 12 miles is on the highway, the rest of my commute is country/town roads (17 signal lights & 3 stop signs-one way). I honestly don't think I could get as good mileage only traveling on the highway.

My F-250 7.3l crew cab 8' box auto 2wd (this is what I consider a truck) gets 18+ mpg and weighs 7300lbs. I think if this truck had a manual transmission I could get 25mpg.

BTW When I fill my fuel tank up, I fill it until I can see fuel. It takes a while but it's consistent.

 

yea, I'd like to know how it is toyota can come out with hundreds less horsepower and worse mileage than a GM. (or apparently ford).
What makes that happen. Same with the mustang.. some other engines.
Get one over here, makes 400 hp 400ft/lbs, gets 22mpg then roll over to this one, its 1.2 litres smaller in a car that weighs 800 lbs less, makes 300 hp 288ft/lbs and gets 14. All engines are just about the same. What gives?

Interesting the 2 engines I'm thinking about above are a pushrod vs a ohc. maybe ohc is inefficient compared to new pushrod engines?

Got to throw in, I got over 20mpg in casual mixed driving (near 30 if I was trying to get there) in my LS2 GTO and 20-22 in my full size gmc extended cab 5.3. I could push em down if I was hammering it a lot.. but we're talking down to 16mpg....

 

You can use this formula to figure it out the break-even point:

Let P = break-even price of ethanol
(Gallons used Ethanol) * P = (Gallons used non-Ethanol) * [P + Price difference between Ethanol and non-Ethanol]

So if we assume a $0.40 difference between the two remains constant (which sounds high to me)

(Gallons used Ethanol) * P = (Gallons used non-Ethanol) * [P + 0.40)]


Assume gas mileage is 16 mpg on Ethanol and 17mpg on non-ethanol
Distance of 300 miles travelled.

At 16mpg, you'll use 18.75 gallons
At 17 mpg you'll use 17.65 gallons

18.75 P = 17.65 (P +.40)
18.75P = 17.65P + 7.06

1.1P = 7.06
P = $6.42

So at $6.41gallon or less it's cheaper to use ethanol. At $6.42, it's either. At $6.43or better it's cheaper to use non-ethanol.


The greater the mpg gain on non-Ethanol, the lower the price parity will be. Also the smaller the price difference between the two, the lower the parity will be.

(e.g. at 0.20 difference between Ethanol and non-Ethanol)
18.75P = 17.65 (P + 0.20)
18.75P = 17.65P + 3.53
1.1P = 3.53
P = $3.21

 

What size tire are you running? How do you like the Michys? How many miles on them?

I'm about to ditch my duratracs for some. (dont use the duratracs for what theyre made for so no point to keep them)

... ^^^ ... I put the LTX AT2 Michelins on when my Tacoma had about 12,000 miles and the Taco now has 20,000 ... (8,000 on the Michelins now).

Stock 4x2 TRD ... 265 / 70 / 16 ... and I love these tires. ...
