Winter Gas Mileage for Auto P5's

Winter or not, 5spd or auto. Our car suck. And are slow, that's why I have to rev my auto up to 4 or 5k to get the hell outta traffic. And that's why I'm getting bad mileage. I get between 22-26 city....Prob will be looking for something that gets better mileage after tax season.

*edit* I dont coast at all. Can't coast when going to work, 70+mph on the backroads baby! woot!
 
I bought my P5 about 3 months ago, but only recenly picked it up from storage (I left it in the Dealer showroom until the snow melted).
I was getting pretty nervous reading all these "poor gas mileage" comments!

Well, I've had mine on the road now for 2 weeks, and I think I get great mileage per tank.
My P5 is a 2002, Manual, with 170,000 kms on it. Bone stock except for K&N drop in filter. Last fillup I did exactly 620 kms when I stopped at the station to fill her back up. Thats 385 miles per tank!
Drive her daily, never have the defrost on, unless absolutely needed, and rarely drive past 125 kph (78 mph) on the highway.
 
Thread resuscitation alert!!!

One of thing to consider with fuel economy is excess weight, especially in a lighter car like the MP5. Empty your car of any excess crap that isn't needed. You'll get a bit more pep too.

Also, I use the cruise whenever possible, and I drive 60 in a 55. As the link below discusses, fuel economy usually decreases dramatically at speeds above 60. I used to drive 64 on my way to work, and by slowing to 60 my average fuel economy went up by 2 to 3 mpg. Now, I don't advocate doing 60 in a 75 zone, that's just dangerous. Keeping the tires at proper air pressure has many benefits (better mileage, better tire wear, etc). It all adds up. My MP5 manual averages 31 to 32 MPG. I've seen as high as 34 on a couple of occaisions.

Here's a few more tips:

I wonder if those that are getting really crappy mileage (20 or less) have bad O2 sensors?

Don't you mean that fuel economy DECEASES at speeds above 60?

And yeah I'm the same way. Driving 75 home from college took me about 2 hours, 30 minutes. I set the cruise control to 60 once to see the difference. Took me 2 hours, 45 minutes. Big deal!
 
well. i havent done any real milage tests on my ride, but it sucks <_< I go through on average $30/week. Even if i drive like a whiteman
 
My wife and I just drove from Idaho to California. We got about 350 miles per tank and averaged 29-30 mpg. I thought it would be a lot more than that. My bro-in-law reported that they got 38 mpg. I don't know if that was a mistake or not, it seems like an awful lot. My inlaws have a Honda Hybrid and they are getting in the 40's, so 38 mpg on a non-Hybrid seems a bit odd.

It's possable to get 38mpg on a non hybrid but it depends on the car and if its all hwy. I used to get that in my old ford aspire... now thats a car that has no power but good gas milage.


threadjack...
Check out this car... 800hp bio rocket impala

According to the May 7 2007 autoweek mag page 14...
They could decrease the power to only 400hp and get est 48mpg.

Well my trip from Chicago and back I was getting an average of about 30mpg and I was going 70-75 most the way. I am enjoying the gas mileage on it when I don't drive like speed racer and such, but even so gas mileage is far better then the old MPV i used to drive.
 
so switching back to my stock air intake from a CAI will make my car suck warmer air which in turn makes the car dump less fuel and my mpg will go back to "normal"?

LOL...I used to avg 35-36 with my aspire. When I first bought it a fill up from empty was about $7. P5 has worse mileage but more power and better looks.

This winter I avg 22-23 for the season and roughly 250-270 miles per tank. I did have a couple of tanks exceed 300 miles.
 
My sedan with a sport auto typically gets 25 mpgs per tank. Doesn't seem to matter what the weather is like or which tires I have on (winter 195/55-15 and summer 215/45-17).

I've drained several tankfulls with non-stop interstate driving at 75-85 mph and got roughly 22-23 mpgs. Usually fighting a head or cross wind at the time too.

Yeah tell me about it those aspires were ugly cars but you cant beat the deal I got on mine 75 bucks and it looked like a damn easter egg! However it ran good. It was a purplish pink color.
