How is your fuel millage?

My best tank EVER was 420 mi. ~30k on the ODO just after new plugs and fresh fluids in the boxes.

 

Mostly highway miles on stock tires in hilly western Pa I was getting 21.5 mpg with the pedal down to 75 mph...with E rated stock-size winter tires I’m getting around 19 mpg under same conditions.

 

lol the best tank i got was 320 on stock tires worked out to around 16.5ish if i remember correctly. now on 6” lift and 285/70/17 and get around 15-16 if i drive like an old man.

 

Somewhere between shitty and sucks. But it's a truck , so who gives a crap.

 

Are you saying you hwy/city average is 24.5mpg, with 17 being the city mileage, if so that means your getting 32 on the hwy?

 

Yeah Im not getting his math either, ha

 

As noted, those sound abnormally high. Are those data for imperial gallons by any chance?

 

It’s hard to believe some of the numbers guys post, when Toyota gets numbers they’re are under very specific conditions. Hell Car and Driver, Motor Trend even do long term testing and rarely get better numbers than manufacturer testing. So when some says they’re gettin nearly 20% better mileage average numbers, they’re either drive very little and or way under speed limits. Anyone driving actual posted speed limits hwy/city aren’t gonna get better(or not by much maybe 1mpg) they what Toyota and the other testers get.

 

MPG is important of course........

But.....I drive/own Tacoma's for reliablity & resale value

 

I was getting 20 MPG but got a new frame and exhaust and now it's more like 17 MPG. Could be the winter gas.

 

18 to 20 combined on p-rated tires & 16" ray10s. I could probably eek out a bit more if i babied the gas a bit more

 

Well I was getting 20 MPG. Got a new frame and exhaust and now it's 17 MPG. Could be the winter gas too but it is annoying me. I find keeping the engine speed around 1800 RPM is best. I also certainly do not drive under the speed limit. LOL.

 

So I don't know how the hell I did it but with driving speed limit runs split evenly on highway and city driving in Kansas I got 24.5 average. But the winter weather we have had over the last 3 days have brought my average to 16.5. full disclosure I have only had it a month or so, and Kansas is flat as a map.

 

Old man huh? I represent that remark. I get 16.5 but My accelerator foot doesn't know I'm a geezer.

 

Anyone talking about using higher octane to improve fuel economy is wasting their money. You'd have to get 3-4 mpg improvement just to break even and that's never going to happen. Maybe 1mpg improvement if you are lucky. Higher octane is more expensive. Consider the following:

87 octane at $2.50 per gallon: If you are getting 16mpg here then it is costing you are getting 6.4 miles per dollar
91 octane at $3.00 per gallon: Just to get the same 6.4 miles per dollar you'd have to be getting 19.2mpg.

 

I get better millage with better gasoline. If I buy from Shell I get more to a tank than if I buy at this discount place called PetroKing.

 

There's a few more factors to consider:

• Terrain like uphill vs downhill vs flat vs pavement vs gravel/dirt
• tire size
• tire weight
• tire tread pattern
• tire rubber compound
• tire inflation
• lift
• additional load including armor, tools, people, etc...
• aerodynamics - i.e. any exterior mods like roof racks, RTT, lights, front bumpers, trac boards, etc....
• Engine: I4 vs V6

And of course miniscule things like engine mods, exhaust mods, intake mods, oil type, spark plugs, air filters, etc.....

 

Reality check... 2010 Tacoma (10 years old this month), 123,200 miles, 265/75-16 tires
4.0 V-6, automatic, 4WD model, double cab
16 mpg combined city/hwy.

This has been the norm for all 10 years.
The best mileage was pure highway, no load, driving to Arizona and back 20.5 mpg.
Next best was heavily loaded but using Mexican gasoline (no ethanol) 19.5 mpg.
In town only, I will get 15 mpg and has even been down to 14+ mpg.
It is really hard to have a tank higher than 17 mpg, but if it's all highway and not driving as fast as the normal California traffic flow (80 mph), I can. I think the trick is to not go over 2000 rpm (about 65 mph)?

 

16-16.5mpg

07 4.0 4x4 dbl cab 204k on 87 oct

 

uh huh
