Hybrid Real World MPG (iForce Max) - post your model, specs, general driving conditions, results:

[chrt]

17.5 mpg via fuelly, 17.7 via dash calculation. 3,000 miles.

The fuel economy is terrible, and I cannot understand why. I came from a 5th gen and I reliability got 20 mpg, whether on my suburban drive to work or highway (typically cruising at 75). I drive reasonably conservative, and even trying to baby my 6th gen I cannot get the mileage up to anywhere near the advertised 23 mpg. The highway range is what really irks me.

Here is a great example of the poor mileage: 90 miles, highway, lightly hilly with a net loss in elevation, light traffic, cruise control, vehicle reports 68 mph average and 16.8 mpg. Wtf!?!?

I did bring my vehicle to the deal for diagnostics and they reported everything was within spec.

TRD Pro.
Regular gas.
No mods.
Eco or normal, I see no difference.

That’s not good. What are your tire pressures? Have you tried premium gas to see if there is any difference?

Not good...you're telling me! Tire pressures are 34 psi as per the in-vehicle readings.

I have not tried premium, and do not plan to. Toyota says regular is fine, and I assume that is what they based the fuel economy ratings on.

I would try a tank of super, just to see if there is any difference. The exact same hybrid engine that is in your 4Runner is in the LandCruiser, and with the LC Toyota recommends 91 octane.

If there is no significant difference, go back to regular.
