Average Fuel Consumption
Hi All,
23i - 2009 - 81500 miles
Just finished a 330.8 mile topless drive (roof down, not shirtless). Hull to Plymouth, four rain showers, one very heavy but I stayed dry. Just finished picking the flies out of my teeth and decided to compare actual average MPG with the average the onboard computer gives.
So, I fuelled the car to the brim on Tesco Super unleaded, pretty much on cruise at 70 mph all the way, apart from a few blasts when leaving a service station.
I refuelled immediately upon my return and the Ave MPG reading in the car was 42.2mpg, obviously happy with that.
I recorded the amount of fuel required to fil to the brim = 36.35L, divided this by 4.5 to get gallons = 8.07
Then divided miles covered = 330.8 by gallons = 40.99 mpg (actual).
Pretty accurate by anyones standards I reckon...

Not bad at all If you divide by 4.54 which is what a UK gallon equates to, then you'll get nearer your DIS figure at 41.31 mpg or you can creep up to 41.37 mpg if you go the full conversion to 3 decimal places of 4.546

Most BMW petrol 6s seem to be surprisingly economical in my experience.
I've done 4,400 miles since my Z4C had a new battery and the OBC is showing 33.6 mpg at the moment which seems pretty good to me.
Although I don't commute, I do like to chase the red line when I get the chance.
But 40+ mpg is impressive (I just don't have the will-power).

Sounds good to me I did Plymouth to Surrey and back this week, top down one way, big diversions each way and was not hanging around. Got 36mpg from mine (calculated based on the fuel receipts as it is going on expenses)

Well the MPG from the computer in my Alpina is 12.4 however that is in london traffic, with heavy accelerating and braking on a regular basis (those gaps in the traffic dont dome along very often in central london)

Will power was the hardest thing, the sun brought out the supercars including two of those insane Mercedes AMG GT Coupes. They sound like a spitfire, incredible... Very tempting not too chase it just to hear it go.......Mr Tidy wrote: ↑Sat Apr 21, 2018 9:06 pm Most BMW petrol 6s seem to be surprisingly economical in my experience.

For comparison, I just finished a 2157 mile trip in my 35i, and showed 28.9 avg.mpg, and 63.6 avg. mph (all US numbers). I am very pleased with that. I have a very spirited driving style, and this vehicle gets TWICE the mileage of BOTH my 4X4 SUVs, (almost 3x the heavily modified FJ Cruiser!)

In fairness, virtually all of the miles were on super- highways with speeds from 65 mph to 90 mph... Baltimore to Miami and back. A good deal was done on cruise control, but some notably empty sections were run in triple digits...... I think this is the best mileage I have ever gotten......in ANY car.
