700+ Miles Per Tank Club

[Eagle11]

So summer is here and the time is right to roll up your windows and turn on the A/C...

So here in PHX, are hitting 115 and 5% humidity. I'm posting my last 3 fill ups. You can see that MPG does take a hit. I do not drive on the highway and my commute is 34 miles RT all on city streets.

I don’t know how some of these Maverick owners get 50 MPG. This has to be going downhill with a strong tail wind! I’m only getting an average of 42 MPG with 50/50 highway and city driving.

You answered your own question, you drive on the freeway....

My commute is 34 miles RT, and it's all city

I adjusted the MPG setting down by about 5% at half the tank in the Engineering Test Mode. Pump calculated at 51 MPG even.

I adjusted mine down 5% as well.

You should try slippery mode full time.
It's the gentlest of all modes.

Well, I did. Last tank was exclusively slippery. The tank just before was again Eco.

Both of these tanks had ~50% Interstate/Highway mileage, some unmeasured portion of A/C. 20% stop/go traffic lights. The balance being state roads with moderate hills or "steep" climb/descent. Equivalent runs between Yeungling (Pottsville) and Three Mile Island (Middletown). Five 100mile round trips each tank.

Result: Equivalent -- in terms of mileage.

However, I now have really nice shiny brake rotors from the slippery mode. It seems, in my terrain, and short light cycles, I end up with far more friction braking in slippery mode. Eco mode is more forgiving with anticipated stopping.

Slippery mode is also poor on long shallow descents. On a 4 mile downhill (last two miles shallow), slippery goes into bang-bang control with compression braking. This is quite disconcerting banging between coasting and braking over and over again. The PID gains in Eco mode are far more refined and give far better/smoother descent overall.

Slippery mode seems more natural on the interstate and surprisingly has better mileage climbing hills/mountains -- noticeably so. However, Eco braking behavior is so far superior to slippery, it remains my mode of choice.

YMMV

My mpg tends to be lower when Itravel on the highway. Around town and taking backroads to work I am at 51.4

I've hit 640 miles twice now before the gas light, yet to hit 700 lol. Unwilling to sacrifice timeliness or convenience for more, but I think it's inevitable that I'll eventually hit it on a long trip on one of my Maine/NH excursions lol.

Is that an online calculator?
I'm trying to figure out the $ difference between say 38mpg and 40mpg and so on per fill up at 4$ per gallon

The program I use is in my Sig, just click on photo

Just got my second 700+ tank completed this weekend. Truck calculated it at 53.3 MPG, gas pump calculated at 51.2 MPG:

I took it out Friday night for a couple hours and had some amazing fuel economy in that trip:

After refueling the truck thinks I'll get 737 on the next tank... Haha, but no, I'm going to take a break from looking at the Electric gauge for a while.

I agree. I mean, do they live in a retirement community with speed limits at 20 mph? I am old, I drive mostly the speed limit, I use ECO ( I know how to use it!) and my average city/highway is 41.

The sweet spot is 35-45MPH for me. Don't use A/C. Use Normal mode. Moderately accelerate to the speed limit and then focus on coasting with as little throttle as possible to maintain speed.

I have a leveling kit and a sport rack installed over my tonneau, so if you're at stock or lowered your results could be even better.

I do all those things and more..also have a tonneau cover>" Moderately accelerate to the speed limit and then focus on coasting with as little throttle as possible to maintain speed." And it is flat here in the Willamette Valley.

It simple, stay off the highway, and learn how to drive the speed limit. My commute I can take the highway or city street, I choose to take the city street, I don't drive over the speed limit, and I don't jack rabbit off the line. The more you coast to a stop the more the battery is recharged, the less time the engine will fire up.

The biggest issue I see is people who get a hybrid and drive it like they normally do any other car. Which is OK, but you are not going to get the hyper high MPG
