More Miles per Gallon (400 miles per tank)!!!!

dkl, you must be stuck on the 405 all day, or racing up at Pomona!

Our '01 gets 400+ on a tank just driving around the mtns, std fare.
My best tank below, which I have posted a few times...568 miles.

Hi guys,

I was kinda resisting replying to thread till now but perhaps you'd also be interested in a slightly different experience?

Keeping at a stead 80mph, and driving regularly from Milan (Italy) to London (UK) (about 750miles) usually takes about a tank each way.

Of course it's a Euro 3.0D 218bhp, but when you're paying $7 (Austria)-$10 (Italy) per gallon - it's insane not to run a diesel

Having had an E39 M5 before, I can tell you it's nowhere near as much fun, but....

I'll dig out a photo later with 999km range and already 250km since the last fill (tho probably someone has already posted something similar in the past).

Glad to see that you guys (with your ultra-cheap fuel) are also keeping an eye on the consumption too

For my curiosity (please excuse my ignorance), it seems that diesel is available in the US (a bit more expensive than petrol), but doesn't seem to be a popular choice? - can you get the diesel X5 models there?

Cheers, Kev

E53s did not have diesel in the US, E70s do have a diesel option.

Kev,
I would have bought a diesel e53 if they were available, especially with the option of using recycled bio diesel (french fry oil) as fuel. But, with that being said, I have gotten some pretty remarkable MPG's out of my petrol 3.0. My best was 34.5 mpg over a 110 mile trip through the rockies. My goal is to break the 700 mile range on one tank. My overall for the round trip was 30.25 and if I had maintained that, I would have been at about 726 miles of range. Of coarse this was mostly at 70mph and not 80. You probably pull those numbers with out breaking a sweat with your diesel.

Are those numbers off imperial gallons or US gallons?

Great job lFlaco!!!
However Your baby had to be running smooth and excellent on MPG
with all this great tune-up: fluids changed, New spark plugs, fuel filter & more.
It was such a very good job for your trip also to keep your car running smoothly.

I'm planning on doing a similar job like yours on my (X5 4.4i) because the MPG
isn't quiet working the way it should on my car, because driving on the highway
shows: 8.5MPG & city shows: 8.4MPG. And I'm thinking this could be related due
to a faulty oxygen sensors, because the car doesn't seem to be consumed that much gas.

I might as well toss in my 2 cents here...

2006 X5 48is on 20's in the summer, I get 22 MPG @ 70 mph ( which is actually 67 according to GPS ). In the winter on the 18's I get 23-24 @ 70 mph. It does surprisingly good IF.. I can keep my right foot off the pedal and use the cruse

Man! I WAS jealous of everyone's 4.4's and 4.8's but after reading this I don't mind my 3.0. Getting about 18 mpg around the city and almost 500 miles on a tank is nice! Not being able to pass somebody in the fast lane, not so nice

I just made some interesting observation:

My mileage consumption has improved - when I bought the car, i saw the MPG from 12 to 17 with occassional 19 MPG... mostly it was in the 16 MPG...

Right now I am observing more of the 19 MPG on a steady basis, starting about from June on... I do not know if I should contribute this improvement to change in driving habits (not really, i still drive the same), change in fuel composition (but last summer there was not such a difference), or the fact that I did a few oil changes rather with short interval (approx. 5000 miles apart) along with using Liqu-Molly engine flush before the oil change and then dumping in 12 fl.oz. of AUTO-RX into the engine, and also replacing the torn CCV membranes, in effort to reduce the blue smoke... I do get the blue smoke on EXTENDED idling, but not on the short ones, like the traffic signals or the traffic jams that are moving... which is also an improvement.

what do you think?

If it were me I would expect I hit the wrong button on the calculator.

I'm going to do all those things you did every month. By my calculations I will be getting 32.2 mpg in a year.

As tires wear down you have more revs per mile, the OBC does not correct for tire wear. GPS logging is the most accurate way to get true MPG.
