I went on a trip through the mountains yesterday. Maximum elevation was 5500 feet, temperatures ranged from 60 degrees (low) to 95 degrees (high), speeds ranged from 45 to XXX MPH.

29.2 MPG

I was stunned.

Car is a bone stock 2005 5AT on a fresh air filter and Mobil 1 oil change.

Using the same technique I used in my gas mileage test (refer to thread in the lounge) I drove reasonably.

I'm finding that the easier I am out of the hole, the easier my car is on me at the pump. Mileage at the high end isn't bad, it's how fast you get there that makes the difference.

Anyway. With the three-hundred million "my gas mileage sucks" threads we've had over the years, I figured I'd start one to say thanks to my G.

Thanks G-Mama.

 

Finally someone else who knows how to get decent MPG.

That low end grunt makes it hard to start slow

You'll be 30+ in no time.

 

yep, that sounds about right. several times i've seen 30+ mpg on road trips.

 

I probably would have been over 30 MPG if not for a few very spirited blasts throughout the day.

 

damn.. how do yall do it?!
I avg. 19.5 and 19.7 at BEST!!!

 

Did you "demand drive" it. i.e. find your speed on a flat road and not change the throttle position up or down hill? You may slow going up hill but you don't use any more gas than the flat road because your cruise control in not feeding more throttle to maintain speed. Then on the down hill side you build speed for the next one.

 

nice, i had not doubt this car is capable of doing 30mpg.

 

I've found that slow roll outs and short shifting in manual mode are the best ways to maximize your mileage.

I recently did a 'test' to see just how well my car could do on 100% city driving.

By shifting at the earliest oppotunity, I was able to break 19 MPG. It was painful in terms of testing my patience, but it convinced me that the G could deliver near-economy performance in terms of mileage if I drove it gently.

This trip was just an extension of that experiment with highway miles in the mix.

 

The other thread.

I hope i will have the nerv to calculate the MPG with my economic mode on and see if i can get over 30mpg in a long trip.

 

To be honest, I was all over the map. The only thing I did consistently was not roll out aggressively. Sometimes I was on cruise, sometimes I coasted (on some of the huge grades where there was no traffic ahead, I popped her into neutral and let her roll out.... YEE HAW!) On some uphills I was traffic limited, on others I had my foot in it.

I didn't use cruise that much because 1) traffic wouldn't consistently allow it 2) I like to do it myself 3) I don't like how the cruise behaves uphill/downhill. There was very little flatland in this route. Only a few stretches between the peaks..

 

Just spent a week in the Adironacks in the twisties and hills (usually 45-55 mph), identical '05 AT sedan. Elevation change was similar, with a trip up to the Whiteface summit at 4,800 ft.
I spent 2 hrs on the 416/401 at 125 kph (75 mph) to get to and from the border, and after we returned I did a few shopping trips and one day of commute before I filled up for the second time.
I still averaged 24.0 mpg (US) over two fills. If I had only measured the Adirondack portion, I'm sure the average would have been much closer to what you experienced.
I had to cool it in the twisties, lest Mrs. Usual lose her lunch.

 

Oddly, I had the same limiter. As I said in my photo thread, I had to use a heat gun to get the wife's fingermarks out of the dashboard.

Got any pictures?

 

The only serious fingermark damage was on the chairlift getting to and from from the ski jump towers at Lake Placid. Luckily for me it was her idea to go up there.

Pictures are still in the camera, I'll see what I can do.

 

same here in my coupe i did 29 mpg going from ontario ca, to las vegas. i was really surprised
