Anybody working to improve fuel mileage?

No complaints here. My stock 2007 with about 90k on the clock gets 20.6 mpg average. Yes, even in town. I drive around in town with the shifter in 4th gear to avoid the dreaded torque converter shudder. Only when im on the freeway do I put her in D to get all 5 gears. I got almost 21 on a recent trip to silverton. Averaging about 20.6 in town all the time,, running premium, or mid grade depending on where I buy gas and how expensive it is.

All stock, no lift, big tires, heavy bumpers... Going to get some bilsteins to lift and level but thats about as far as Im going to go.

Does the trd intake and exhaust help fuel mileage? Any other mods to bring that number into the mid 20s?

Re: Anybody working to improve fuel mileage?

Unless you are a hypermiler IMO reaching mid 20's is not possible. The fact that you are achieving 20-21 with big tires and heavy bumpers is impressive. adding lift and leveling I wouldnt be surprised if your mpg goes down.

All I can offer is keep the clutter and junk out of the FJ, keep it clean and keep on trucking.

Every time I buy something else for the FJ I get more smiles per gallon.

Re: Anybody working to improve fuel mileage?

Never saw 20mpg even when Jade was perfectly stock.. Sometimes into the 18's. Mods have gotten me into the 15-16 area even when I'm trying.. I saw mpg go down each time I increased tire size (weight).

Did you mean "no lift, no big tires, no heavy bumpers"?

Re: Anybody working to improve fuel mileage?

Yeah, no lift, no big tires, no heavy bumpers. Im looking for some good tires in stock size, and researching mild lift using possibly tacoma shocks and springs.

Re: Anybody working to improve fuel mileage?

x2

you are doing incredibly well

no, the intake / exhaust changes won't result in anything much (besides more noise, which is their point for most people)

With my supercharger, and large mudflaps, I get 14mpg sometimes, usually mid 13s, especially if I drive at 80mph.
Getting only 200~240 miles per tankful makes me want an aux tank (=more weight, though)

Skip the Tacoma shocks and springs - different weights, different valving, different performance.

Learn from the grizzled vets - buy what you can/need vs what you want, buy once cry once, don't be in a hurry to throw money at the FJ to mod.

Those numbers are almost too good to be true on a single VVTi engine, especially with any weight-adding mods and bigger tires. Truly achieving 20.6 MPG in around-town, stop-and-go driving is phenomenal.

Can you provide some specific info on:
1. Exactly how you are calculating your fuel economy numbers;
2. How you are correcting your odometer readings for the larger tire diameter;
3. What tire size you are running;
4. What weight-adding mods you have made (weight of bumpers, or brand & model, sliders, skid-plates, etc.)
5. The elevation where the majority of your driving takes place.

This will help extend the range of reliable fuel economy data that forum members have provided.

Re: Anybody working to improve fuel mileage?

Yes,

I offset the 15MPG with an all electric Chevy Bolt, incredibly efficient.

FJ is the wrong platform for sipping gas.

If you care about MPG on the FJ, don't lift it. The more you expose the front tires to the wind, the worse your MPGs are. And stick with those hard street tires, the big knobby offroad tires grab the air.

Kudos for 20+ in mixed driving. The relative inefficiency of a built-to-offroad truck is why I only drive mine to the trails and back. For everything else I drive a Lexus sedan. The real MPG fix for the FJ is to buy another car that isn't an FJ.
