What is your average MPG

[TriGem2k]

16-18MPG depending on how i drive...

[velvet_jones]

23 mpg-90% freeway driving 70-75 mph.

[Perfectlap]

too low!
damn gas went up again. $2.77
$30 got me 3/4's full.

(yeah I'know other's have it worse but you should see how much I pay in car insurance and NYC parking and these toll roads are getting ridiculuous)

When the weather is cold I get about 20-22 mpg. I tend to short shift and go easy on my cold tires until I'm at 180 temp.

When the weather is nice and the top is down I drive fast and hang out in third gear like its a long lost friend. 17 mpg.

I got less than 20 mpg around town before my new 02 sensors. Now I get about 23 mph in town and over 25 on my "road trips" to the country where I hammer it the whole time. Go figure.

If your boxster has 60k on it, replace your 02 sensors before they go out and throw a CE light... you'll be glad you did and enjoy the fuel savings as well.

I believe performance went up too after I changed them, but that's just my butt dyno.

OBC says 25-26.5 in normal (95% open road) driving. Almost no stop-n-go. Regular but not constant trips to redline in lower gears,

Got almost 30 on mostly Interstate trip to Tampa area and back in Dec 05 @ 80 mph average.

Early months 22+ mpg until broken in.

I was getting about 23-24 on my daily driving and 30 on my long highway trips and I was getting a shudder sometimes as the car reved down to idle....I called the dealer service group and was told that my mileage was "too good" and that I should drive the car harder...more 3.5 to 4+k plus shifts. Well sure enough my city mileage went down to about 22 and the highway stayed at 30 and the shuddering is drasticly reduced....can only assume that my city driving was "clogging" the system. Only about 8500 miles on the car to date....bought the car with 3500 miles on it 5 months ago...must have benn someones weekend car but is now driven daily. Very happy I have a 100k CPO warranty!

I really wish I knew how you guys are getting fuel economy in the 20's...

[bhduxbury]

average about 20.5 with compressor on, about 21.5 with it off.

[Uncle Bob]

19 ~ 23 for me at just about 3,500 mi.

You keep your gall fill up receipts and write your mileage on them. Then create a database and track you mileage, how many gallons you put in the car since you last fill and your new mileage on your next reciept. Once you have 2 receipts you can calculate your last trip from the first mileage record to the second and how much gas you put in the car the second time and see you traveled X miles with X galons of gas give you miles/galon of whatever. Then everytime you fill up just add it to the database and you can see exactly what your MPG was for each time you fill up.

You can then make your database do other things like average miles per fill up, average price of a gallon, average MPG and stuff like that as well.

my daily commute is 27 miles, with 24 miles on the interstate. i avg about 24 mpg for the commute and about 29 mpg on weekend trips. this if for an 03 S

Hahaha, I didn't mean "I wish I knew how you guys were CALCULATING" MPG, I meant "I can't believe you guys are getting such good mileage!"

Although you do raise a good point--if we're not all using the same method for calculating our MPG, this exercise is a bit inaccurate. I'm just going by what the onboard computer tells me my MPG is. I reset it whenever I fill up and then notice where it's at when I refuel.

Mine's always around 17 to 18 MPG when all's said and done. Not enough freeway driving I guess...

Eric - get a job 50 miles from your home and drive around 75-85 mph to and from. And don't use use your 987 for short trips to the grocery store. BTW, Karen and I just got a Vespa for our town errands.

[eslai]

"Consider Remaining Range", yeah I found that very amusign the first time too. So polite, like, "Now, I know you're not a dummy and you probably already know this, but you, well... you might wanna think about gas soon, y'know what I mean?"

A Vespa. That sounds good. But driving from Mira Mesa to Poway every day (a wonderful, traffic light strewn drive ) probably wouldn't be so fun on one...

I really miss the days where gas was ONLY $2.77 a gallon for premium.

I get mid 20s all over the place, but my driving is probably 70% highway.

I just filled up at $4.11 per gallon, and that was the cheapest around me here in Mercer County, NJ.

This thread is great for tracking our nation's gas prices. Perfectlap's post quoted above was made in April of 2006.

One thing that has to be taken into consideration I think when talking about MPG is that while someone's MPG might be lower because they do mostly city driving that that person is probably driving a shorter distance, so therefore using less gas. So while I may be only getting 15.7 MPG, I'm only probably driving 5 miles to get downtown as opposed to the guy who has to get on the highway for an hour. Just something to think about.

[adrewishprince]

I was getting 22-24 MPG on the highway, then I cleaned my MAP sensor and it immediately jumped to 27-29.... I was shocked it had that much of an effect.
