Best gas milage

[DrJason]

I've put about 2000 miles on my Z with an average mpg of about 21 without resetting the computer yet.....I'll admit my driving habits are probably not the most conducive to maximum mpg.......soooooo.....I'm going to try this experiment for this week; I'm going to try my best to drive the "right" way to get the maximum mpg and see what the result is.......has anyone else done this?

So far after 1 day: 26 mpg with all city (suburban) driving

on a couple of long highway road trips I've gotten in the low 30's

You have a lot of long highways out in WI.....I rarely go on the highway anymore.....I grew up in Waukesha Co. and went to MU before moving to the east coast 11 years ago

[JeF4y]

Yep, living in Waukesha Co right now. Closing on a condo in Atlanta the end of this month though. Gotta get the hell out of the snow belt.

Most of the highway driving we've done though has been on roadtrips either to the Northern part of the state or to Southern IN.

I get 14 mpg driving around town with a lead foot.

[richard in NC]

I average around 23 mpg, mostly commuting. I have gotten nearly 30 on a long highway trip. The most recent 1600 mile trip with LOTS of hard driving averaged 23.

Shouldn't we just enjoy our wonderful rides!
The awesome sound of the exhuast make me want to step harder each time I drive my Z4!!! :-)

[ewps]

21ish

[mikeinaustin]

27 on the ride to work today, basically no traffic on a mostly highway route. going home i expect it to tank to (guessing here) 14-17.

The best I have been to nurse out of my new sDrive30 is 29.7, but it usually runs around 25-27,mainly cause I drive like I just stole it - can't help it, it just drives too nice...

[DrJason]

after 3 days the average was at 24mpg.....then I said f*ck it this is not fun I'm going back to driving like a lead foot a-hole

[patrice03]

city drive with heavy traffic, short distance and cold engine: never better than 15mpg. quite poor

city drive with little traffic, expect 19mpg

motorway , between 30 with cruise control (good!) and 27

[MilitaryE89]

if I fill up at the beginning of the week and just drive to work and home and errands I can expect a full tank to buy me just a little over 200 miles...ungh! Going on trips, forget about it...Autobahns eat the gas...I cruise at about 115 to 120 and it gets about 18 mpg doing that...if I see ricers on the autobahn then naturally my mpg goes down to about 6 loll

[BarrowJon]

After a trip to High Point NC am now officially broken in with almost 1400 miles on the ODO. Drove betweem 70 and 80 MPH, showing 71.2 as my average, and was quite amazed with my gas mileage coming in at 29.4 MPG

My friend, try to remember these numbers the next time you're on the autobahn and feel the need to chase down the 911 TT. Save the earth and don't drive your sport car fast!

Copied from the "Physics of Racing" http://phors.locost7.info/phors06.htm (air pressure is the weight of air (coefficient of drag) on the car as speed increases.)

Best ever on 200 mile run was 31.2mpg (Imperial Galls/Welsh Miles)

[riccis]

Picked up my car yesterday (Saturday) with half a tank and am shocked at how fast the petrol goes. Have managed only 24mpg, taking it very easy with a mixture of city and motorways.

[yabbanoname]

well my 35i prefers refills between 500 and 580 km (312 to 362 miles) on 98 octane. On 95 octane it's nearly 80 km (50 miles) less

[michal12]

Did you also notice any change in performace or it makes no difference?

I guess 24mpg in city is not too bad? But it should improve further after brake-in.

yep, it differs enough to spend the extra money
