No im talking aboot my taco. 3.4 Sorry didnt specify.

 

i checked my gas mileage today. ran it down till the gas light came on. when i filled it i put in like 16.2 gallons. and i got 285 miles out of the tank. so thats 17.6 mpg. thats like 60/40 city/ highway driving.

my experience is my mpg's go up during these hot louisiana summers. goes up a little more with more octane too. truck info in signature

That's all folks, I'm out for a while

 

So it looks like your averaging about what you should. Just wondering what the random spikes in mpg are from? either way thats great mpg.



I know yours is a 93, dont think it matters.
Its funny it shows the pictures of the 2wd's.
Glad I dont have the 3.0 auto uh...

 

I forgot to post again after driving conservatively. Also, I did my math wrong the first time.

Driving hard - around 14-15 mpg

Driving slow and steady - 17 mpg

Driving hard for me is going 70-75mph on the highway and really pushing down on the pedal while going up hills. Driving slow I was going about 60mph on the highway and I would try to barely touch the gas pedal at all times. So yes, I went pretty dang slow.

For a 1994 22re Pickup 5 speed, 4" lift, 33" MT's, stock 4.10 gears... I think that's pretty good. In a few months I'm going to sell my ATV and buy 35" MT's, 5.29 gears, and a truetrac limited slip. I'll post again after a tank of gas.

 

Variations are from exactly that, ha, variations.

When I drive to and from South Dakota and Nebraska (a lot) if I can take my time and go bit under I get great mileage. If I'm in a hurry and have to downshift and floor it up hills and do a few over, it tanks.

Most of the fluctuation there however is from the fact that I drive very conservatively when I commute, but when I go wheeling or messing around for fun I don't hold back.

I am a firm believer in getting the best MPG possible when commuting ha I like to, it's like a challenge. However, when wheeling, don't even think about it.

 

'94 S/B 4WD 22RE ,5 speed,150,000 engine miles excellent running condition typically 23-25 mpg at all speeds. Stock size tires about 38-40 psi I live in Fairbanks Alaska, and yes it helps to keep the intake air warmer during winter simply add a 'winter front' as we call it, jip it to match the ambient outside temps. These trucks are super all around

 

Ya K

 

Got just over 19 this last tank. I'll post it up later.

 

93 4x4 single cab. Fresh 22re. Did 21 mpg last tank.

 

92 4runner gm 4.3 , l460e , 35 " tires , 4:88 gears , sas. Runs great.
weigh's 4900 pounds ! I get 11 to 13 mpg combo driving. 16 to 17 mpg hwy fully loaded wheeling for the weekend.

 

i get around 15/16 MPG city, and 21MPG Highway, running stock rear gears and tire size for my 4x4.

Bone stock with just over 100K all original except for 31X10.5 DuraTrac's on Cragar soft 8's
Best tank 21 mpg
worst tank 18.6 mpg
avg 19.5 mpg

It seems weird but my city to highway variation is very minimal

 

around 17mpg

 

weird to see that even the old is getting the same gas mileage as the new

 

Newer isn't always better.

 

yeah i know, not really my point, it was always my assumption that engines were improved to get better gas mileage as the years roll ahead. not true in this case.

 

87 pickup 22re, 4000 miles on the rebuild (that's 6400 km for you metric guys)
bored .020 over, 261* cam, thorley header, 2.25" exhaust all the way back, no cat, late model plenum/throttle body
4" lift, 31x9.5 on 15x10 steelies (not much choice, trust me)
I get about 16mpg in town, depending on how I drive, and ~20 on the highway at 65 mph, ~17 at 75 mph

 

Seasonal fuel blends aside, it's because hot air is less dense. This means less drag on the vehicle exterior and it means the throttle is open more to make the same amount of power required for maintaining speed. A wider throttle opening means reduced pumping losses and higher volumetric efficiency.

It's the other way around: hotter air means less density. Less oxygen and the same fuel means a richer mixture, but this only applies to "dumb" fuel systems like a carburetor or mechanical injection. EFI fully compensates for temperature and air density.

Generally speaking, it is true. The key is that vehicles keep getting bigger, heavier, and more powerful. Look how much larger a new Tacoma is compared to a pre-'96 truck, yet economy figures are comparable between similarly-equipped trims.

 

EFI does compensate for temperature and density. That's what the O2 does. It senses too rich a mix, leaning it out. It would be interesting, however, to run a wideband O2 and pump 120* air in, then 20* air in, and see what kind of a difference it actually makes.
