Poor Gas mileage even under 'normal' driving conditions

My take is that these cars should all be getting pretty much the exact same gas mileage. The reason they don't is because we all drive them differently, under different conditions. I can squeeze 32 MPG out of my 350 and I bet I could do the same with anybody else's *stock* 350. 32 was difficult but I did it. Filled up 1/10 of a mile from the freeway, 65 MPH cruise with cruise control, AC off, windows rolled up, *all* freeway. Within 28 miles the car hit 32. I'm confident that if my trip were considerably further I could have gotten 35. I think Lobux hit 35 one time.

yes our cars are capable of getting great mileage but the problem is if we drive that way consistently to achieve those numbers we should have gotten another car.. or 350 owners should have gotten a 250. Nobody should buy a 300hp car so that they can cruise around like a granny. We paid for the extra power why not use it sometimes?

someone should *bump up* the 250 horsepower depression thread

My lifetime avg is 22.4. My tank avg is usually 22-23. I drive a mix of hwy /city, but try to stay out of traffic. I get 26-27 on the hwy and no, I do not baby my car. I consider this a economy car with *****.

In daily commuter traffic, with an average speed of 13 mph (currently), my last tank average was 20.1 mpg. This was mostly normal driving and coasting. With more aggresive driving habits (but still under 4.5k rpm), my avg drops to the 19 mpg range. Keeping ultra conservative, I can probably get around 22 mpg, given the same daily commute.
Highest avg has been 31 mpg, all highway cruise, after a fillup.

One thing that helps with learning how much gas you're using is to leave your car display in the live MPG setting and I think you'll see where you're wasting gas kind of like a live biofeedback meter. It was using this display that I learned using snow mode on the freeway helps a lot. Still i don't care about getting the best mpg. I just drive how I drive normally mixed city/hwy mixed granny style and full throttle occasionally and get a decent 22mpg. Also maybe some of you folks have bigger heavier rims stereo equipment to lug around or have the AC on all the time? No way this car should get under 20mpg unless it's all stop and go city miles.
i use that dis all the time on freeways... it reminds me to stop acel...

I know I have a 250 so my numbers are different, but here's what I get:
I drive 16 miles of highway everyday on my 24 mile round trip commute to and from work. I'm usually cruising between 70-80 on the highway depending on traffic. With gas prices where they are now and only going up, I've started babying her while on the highway and I've gone from averaging 23.5 on a tank to 25.8 per tank. I'm hoping to push my average up to 27. I also try to coast to red lights as much as possible.
Driving from San Antonio to Dallas, I averaged 35.1 MPG with a Avg Speed of 71 MPH according to my dash display.

My experience is not yours at all. I've driven at speeds from 65 to 80 and not seen a significant repeatable change in mileage. I can drive 80 and get 28+ mpg. I have driven 65, with the cruise control on so I couldn't accidentally speed, and seen the exact same mileage.
What I have documented is shorter runs consistently produce lower mileage. Every cold cycle hurts economy dramatically.

I know that I have hills around the Bay Area and the way they designed the freeways leads to lots of ups and downs. I usually have cruise control on at 70 and get more consistent, but at faster speeds, I have to deal with slight inclines and declines (for those who are in the area, you'll notice that CA-237 isn't as flat as it could/should be, nor any other freeway for that matter).True.. my commute is only about 10 minutes, which includes about 8 minutes of highway time, so that may be killing my mileage. But that's still better than what the OP was talking about.
