glad to hear your getting good results with mixed driving.

Yep, right now I'm half way through a tank. Been doing all city driving. Average speed so far is only 25MPH and all the AC is running
. I'm sitting right at 22 MPG. Once we get on the hwy this weekend that will rise.

I'm more than satisfied with it so far.

This is with start/stop always on.

The only thing I do that some may do differently is that I run 100% real gas. No Ethanol. Real gas always nets me better mpg in all my vehicles than Ethanol and I can personally justify the extra expense. Some folks can't justify it, while other folks just don't care.

Just to follow up on this. That tank lasted until last Tuesday. We did a little highway driving over the 4rth of July weekend and it ended up at 23.7mpg for that tank of fuel.

Still more than satisfactory for me.

It's also worth putting the old calculator to it as well.


I'll have to do that next time I fill up to check the accuracy of the computer.

I feel this discovery is like the Jeep in terms of Fuel Consumption. The Eco is on, when I drive, but I disable the auto/stop because it hot in NY now and when I come to a complete stop on a red hot the AC turns off. Any other suggestions or I have a to break in the car before I notice improvement in term of fuel consumption.
I feel the auto stop feature is the biggest contributor to our better than advertised fuel economy. I was never sold on auto stop, Im a believer now for sure. I have a feeling that if we disabled it most of the time our MPGs would drop drastically.

We have 95-100 degree temps right now and we have AC on and ventalated seats on..I still leave the auto stop on...

I just did a road trip from nyc to hershey park roughly 180 miles 1 way and found I get about 300 miles on a full tank gas, is that good?
No thats actually terrible....IF youve used the whole tank of gas (18 gallons). Youd just have to fill it up then divide the numbers of gallons you just put in by the miles on the tank of gas. So if youre just gettiing low and you still have around 3 gallons left and then fill up with only 15 gallons...well thats a little better at 20mpg. But thats the only way to get an accurate mpg reading. BTW, even 20 mpg for a road trip would be pretty bad.
Anyway, come back with moe exact numbers and we'll be able to see whats up with your fuel milage.

Disco can hold 18gallons? When I was empty and car said 40miles to empty, I filled it up, it was only 14gallon.
The specification say it's got 18.5 gallon capacity. So you had a little over 4 gallons left in your tank. And the miles to empty feature is probably reading conservatively.

When I run it "bone dry "I usually get about 15 gallons in there when I fill up. So this thing has a really large amount of reserve tank if the capacity stated is correct.

I noted yesterday that I had 180 miles on my current trip meter. I was averaging 23.3 miles per gallon. And it said miles to empty was 120. Which would have put me at 300 miles on the tank of gas. That would not have jived with the current average mpg reading. So it obviously adjusts with time and driving style. But I am going to see exactly what my gas mileage was the next fill up using the old calculator method. :)

I just did the weekly top off.

So here's the real world deal on mpg in my experience. We put 206 miles on since last top off. I topped off with 9.8 gallons of fuel. That gives me 21.02 mpg for the week. That's with at least 75% city driving with an average speed of only 27 mph. A//C always on, S/S always on, ventilated seats on 50% of the time.

My trip computer says I averaged 22.8 mpg. So it's a little bit optimistic and I'm not sure what kind of variables it has in its programming....

So there ya go. Either way you slice it, I'm happy with fuel consumption. You

The fuel gauge fix is software
My dealer wanted to drop the fuel tank and replace the fuel sending unit. I told him that I heard it was a software issue. He got a little testy and said...
thats what everyone always thiinks. and..you cant always trust what you read. I laughed at him and sent him all the bulletin numbers he needed to handle the problems I need handled. So if that bulletin says its a software fix, they better do a software fix and not a fuel sending unit.
