Replying to: fedlawman (Mar 24, 2008 8:08 pm) Nope, that's not it. The car is only 2.5 years old and I've been doing the winter tire/wheel package changeover thing. Neither set is worn down (though I have a cupping problem with the OEM tires and I'm going to run the winter tires longer this year, perhaps until near the end of my 3 year lease). |

I check mpg by hand too, on a regular basis. I was just wondering how accurate the readings from the car are. It seems that your experience has been the same as mine in that the readings from the car are a bit optimisitic. You certainly are getting good gas mileage for a V8. I think that BMWs have remarkable fuel efficiency for such powerful engines. I'm getting 24.5mpg overall from my 330i; that's roughly 60% highway, 40% local. I came out of a G35, which got about 22mpg with the same driving.

Replying to: davidd3 (Mar 25, 2008 1:50 pm)  As I said before, I found the same thing as you with my 545i. The car's readout was always a bit too optimistic. After I found that out, I started keeping the mpg stats. by hand. I keep a pocket calculator in the glove compartment for that purpose. After the first year, I became less enthusiastic about "keeping score". From the chart I kept by hand, I averaged about 21 mpg over 9000 miles with 70% highway, 30% local errands. Pretty impressive for a powerful V-8, IMO. I'm sure the mpg would have been closer to 21.5 or so, using the car's readout. I guess BMW wants us to believe our mpg is better than it really is so we keep coming back for new BMW's!

| Mine is indicating 27.3 mpg over the past several thousand miles, about 60/40 highway/urban with the occasional 150 mile trip. | |

On board computer has calculated 28.3 to 28.5 over 46,000 miles 90/10 highway/urban. I commute 90 miles round trip daily. Manual calculation thru the first 20K was 27.9 to 28.3. Regards, Kirk |

| Our 2006 325i Convertible with automatic transmission got 29.4mpg from Sarasota to mid-MI a few weeks ago. A 2 day trip running 70-80 mph most of the way fairly frequent food and rest stops. | |
2006 330i A/T. 33.1mpg according to on-board computer for round-trip of 250 miles, almost all highway  mostly 70mph.

I've had my 325i and it has about 55k miles on it. Just recently drove from NYC to Boston. I got 28-30mpg on both legs of the trip w/ A/C use and a fully packed car. 2 kids/ 2 adults and luggage. I averaged probably around 75 touching 90 occasionally. Usually I get 22-25 in the city driving between NJ, NYC and Long Island and Hwy around 27-30 depending on how spirited I drive. I've seen the computer hit 34mpg on a fresh tank and right onto the hwy, but only going about 60 on the flats. Usually can't stay like that for long. Looking to get a 3 series convert, after I trade in the sedan for a minivan. |

2003 330i zhp 6-speed Suburbanish-city driving: 19 mpg Highway 65 mph on cruise: 34-35 mpg Both on premium; regular does not seem to make much difference. The city number is a little disappointing as my wife's RX330 does 17-18 mpg and it is a big lump. Sure hope they start doing hybrids or importing manual shift diesels. |
