The 500 Mile Club. Can you join? Hypermilling

[ienjoydrifting]

Ok, so this may not be the whole idea of owning an x5, But I also like to be as green as possible. Have you been able to make 500 miles out of a single tank? My record so far is 527 miles on 24.241 gallons, That's 21.7 MPG in the 4.4.

My average is 17.66 mpg right now over the past 30K miles. But about 40% of those are pulling my trailer.



So lets post your mileage and lower your carbon footprint.

2002 BMW X5 4.4
315-35-20's
Intake + Xpipe.
527 on 1 tank - 24.241 gallons. 80% highway, 20% city

Also, I have managed 351 on 24.102 gallons pulling my M3 on my trailer. 5200# total on my 20ft open hauler. Thats 14.6 mpg. 100% highway.

That must be freeway miles ?

No way I'd get that out of mine. Then again I live and spend most of my time in a built up area which means there may as well be a hole in the fuel tank.

I'd say I'd get max 300 miles out of a full 80 litre tank. And at €1.46 a litre here in Ireland at the moment (or approx. $7.63 per US gallon), it's painful.

500 miles a tank is very good! I never let the tank go to the yellow warning light, but I have gotten 400+ miles on ~20 gallons which would be around 20 MPG. This is around 80% highway and 20% city but I wouldn't consider it hypermiling since I'm usually going 75-80MPH.

Our car's OBC states that we've gotten 18.5MPG over the last 20k miles and that would change the driving to 50% highway and 50% city. It amazes me that cars nowadays get 30MPG highway when I'm happy reaching 20MPG.

Geez, you driving downhill for 500 miles? I can get around 400 miles doing mostly cruise control on flat straight freeway in my '03 4.4 all stock.

As I have posted a few times before, my personal best in our '01 X5, which is a 3.0 not 4.4...it is a manual 5 spd and it has considerable rpms at speed. This best tank was obtained on a run from our NC house back to NJ to see the kids, in June '08. 568 miles!

A/C was seldom used as it was overcast and cool for most of the northbound run, and I had the orig. BStone Turanzas on the 132s, and they were at the wear marks.
I was literally on fumes when I gassed up and took that gauge shot.

Easy. My 05 3.0d has done 713 miles on a single tank. Okay, I know I'm a smart arse...

[lemans4.8]

I get 300 if I'm lucky.... 05 4.8is.... 95% city driving

[wallyx5]

Hey Motor David nice work. I did 488 yesterday, but 511 was my best.

[jst2878]

thatts one of those specially made X's out there. Much better to get than a lemon.

563 was my best on an all freeway trip through the mountains from PA to Toronto with AC going an wife and kids and luggage. A can of bg44k in the tank, new tires running 38psi and cruise @ 70mph.

Driving style is the biggest factor in MPG. Next is tire pressure (& type to an extent). Next is weight. Everything else is just minor friction losses that are used to get the vehicle moving.

And of course - your emission system should be functioning normally.
