To get good fuel economy. The picture posted below, is not a joke. I took this in the driveway tonight, right after I got home from work. This is in my '08 Impala, running on E10. I managed this number by keeping to a maximum speed of 55 mph, utilizing basic fuel mileage maximizing techniques, no a/c, and with a modest tailwind.

The screen had posted as high as 35.3 mpg, but the hills near my place, pulled the number back down.

That's pretty goll-darned awesome! I'd be happy with that in an economy car... to get that in a large family sedan is unbelievable!

 

[Kamshaaft]

Impressive, and I wouldn't doubt you even if you didn't post a picture because even though not that many people will believe it, it's very possible to achieve (I said possible, not easy ).

Going 55mph is a very good move, seeing as wind resistance goes up by the square, but I hope you're travelling in the slow lane . People will be riding your arse otherwise (the jokes on them though).

I'm not so good with the mpg myself, I just can't help myself to drive around at the top of the powerband, not the middle of the efficiency band. Gotta plant my foot for the roundybouts and step it out for the folks.

 

[Cloudydaysbehind]

Yeah, bro-in-law's Corvette z06 is a steady 28 - 30mpg on the DIC. Gotta love it!

 

[BrickTamland]

Even though DIC's are usually inflated blink:), that is some impressive mileage.

:lmao:

That really is impressive though. I pretty much gave up trying to get over 30 MPG in our Malibu. 28-29 is all I can average now.

 

[fenderbender]

That's great, but how can you stand going 55 all the time? You should see what your numbers are going 65, 75 ect.

 

[BigAls87Z28]

I agree. Ive tried to do 65 on the Parkway, which is still 10mph faster then posted limit, but just cant do it. I dont have cruise on my Caprice, so its hard to keep the foot there without it wanting to go to the floor....

They aren't too bad, they have a small margin of error. nd I agree, impressive fuel #'s. I'm curious to see what he gets if you upped the speed to 65?

 

[mikmak]

That's a smidge off the average in my 2.2l Vectra! (of course I drive the wheels off it, but still)

The margin for error on my DIC has maintained a consistent .9 mpg higher than the calculator. As for driving faster, I have driven faster, when my co worker has pushed us a little on the late end of getting to work on time, and I've allowed impatience to take over. That has always resulted in about a 4 mpg drop according to the DIC, just over a 50 mile drive.

As for those who have questioned how I can stand driving slower? That's easy. Driving faster doesn't save me any time, and putting $100 per week in gas in the car to commute will motivate one to find a way to cut the bill back. I've had that reminder every time I've gotten in a hurry, as I end up stopped with everyone else at the exact same lights, that I otherwise would have caught up to as they were changing.

Driving slower does take a little getting used to. Once you do, IMO, the payback is worth it. My Cherokee is the one that has the greatest response to slowing down. Mileage on that one will increase by a full 11 mpg.

Take my license, all that jive/I can’t drive 55! :drive::yup:

And he is in TEXAS! It is so flat you can drive 155 and you will fall asleep, the car will hold course, maybe go off road but you'll still wake up nice and rested somewhere in the Kileen area :lmao:Just be happy you aren't anywhere near College Station because the cops there are pricks!

 

[2005 Equinox LS]

My 2000 MonteCarlo got around 33 on the highway when I would take it on trips. I actually kind of miss that car. Maybe I will try to find a 2006-2007 one when I turn the Equinox in.

 

[SirRaven]

You know what though, you might be getting good numbers with your car/engine, but I would say that is more your driving style then the car. I bet if you would take a Cobalt XFE and drive it on your same route the same way you would get 40+. Some people just dont realize that if you do change your driving habits you can really increase your fuel economy.

 

[likearock00]

Yeah, I can get around 25 if I drive like a snail too. Sorry, but I got put my truck in the wind!!

 

[cyclone]

back on my old s-10 i put a chip in it, i got 23! it was a ZR2!

Oh, I could easily take a Cobalt XFE well over 40 mpg. When I had a 2003 Prius, I was logging as high as 58 mpg on my commute. It's still nice though, keeping a large car well north of the 30 mpg mark, and having the room to comfortably carry passengers.

Yup. My drive's only ~30 miles each way, and I've found the exact same things to be true. Some days I'll notice a certain car go past me flying, only to catch up to it at the stop light near work (10 miles further on). My 08 'bu LTZ is averaging 29.0 overall so far because of learning this restraint. It's fairly easy to drop it if I get impatient too.

Absolutely. But if all you're after is 30+ mpg, and you have the right driving conditions (no matter what, if you're in stop'n'go LA traffic, your economy will be lower), you can have your cake (V6) and eat it too.

And to have plenty of power to spare if you NEED to use it (or just feel froggy).

 

[dauntlessVsix]

I've averaged 30 mpg with my V8 T-bird on several occasions. Keeping the 4.6 at around 1800 rpms seems to offer the best results. Casually driving around town, It always shifts under 2000 rpms so the city mileage hasn't been terrible either.

I did exactly that (34.4 instead of 34.6) on flat highway with my GF's Impala with the cruise set on 60 with no traffic or stops in a 50 mile run. I couldn't believe it so I really didn't tell anyone. It has the 3.5L VVT in it. (see sig) So I figured that was the sweet spot (speed and road conditions). It usually gets 30 highway on a flat run at higher speeds though. But that is still pretty good for a larger car with a v6 I think.
