3.4 mpg

Hey what's the average fuel mileage for a 3.4l with 2857017 at tires?

 

Gear ratio? Auto or manual?... just kidding. None of that really matters. You should be around 15-17 MPG. I have 285/75/16 wildpeak MTs with 4.88s and avg 16.5

 

Not sure of ratio. It is automatic.

 

If you haven’t swapped gears, you more than likely have 4.10s. You’ll probably be closer in the high 15mpg with the 33 inch tires. But it’s also dependent on how much hwy/cty driving you do.

 

Drive 12 miles a day on freeway . I can watch the fuel hand move.

 

What are you getting per tank?

 

About 130 miles.

 

You should be getting double that.

 

Any CEL or rough idle, hard starts, or anything like that?

 

I know. It's got 154000 miles. I just got it 3 weeks ago. Its had a ton of work on it. Toyota installed new frame. New axle shafts. Radiator, exhaust, air filter, I just thought mpg would be better. Dont know how old ign parts are, wires look brand new

 

No cel, starts great.

 

When you get to “E” does your tank take close to 16 gallons?

 

Yes.

 

Have you plugged in an OBD2 reader just to be sure of no stored codes? Previous owner could’ve pulled the CEL bulb. There’s some squirmy bastards out there.

 

I just figure it's the bigger tires. Sure has lots of power.

 

I have not. It does a bulb check when u turn ign on. Also cant get key out of ignition half the time . Have to keep taking in and out of park.

 

Well, color me stumped. That may require some professional looking over.

 

I appreciate the help. I may pull plugs and look at them. Also fuel filter.

 

I get around 19.5 on the highway with my wild peaks on. Generally around 320 miles ro a tank.

 

Size tires and gear ratio?
