The 500 Mile Club. Can you join? Hypermilling
 

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...

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

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

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.

I don't fully agree. Overcoming a vehicle's inertia (due to its mass) and its aerodynamic drag are the two biggest factors in fuel consumption. The inertia factor comes into play in stop-start driving while the aero issue is more important at higher speeds. Now you drive (ie. lead foot verses feather foot) is also a major factor, as is your driving environment, ie. city or country, flat or hilly etc. Then there's the other issues like rolling resistance (tyres and tyre pressures), efficiency losses in the drivetrain, etc.

I agree, how you drive is more important than anything else. in fact, they now have developed software that 'softens' your acceleration and other driving habits so mpg is better. they claim 5% for this alone.

Our last round trip drive from Reno to San Jose netted us a calculated average of 20.7 mpg so I guess I could get close , but only with freeway driving.

For any given identically specced vehicle, I believe your driving environment and driving regime is more important than driving style. However, your driving style is still critical especially in a stop/start urban situation and in a relatively heavy and powerful (at least in V8 guise) vehicle like an X5.

Just out of curiousity are these mpg figures because you are on low octane fuel in the US or because you are talking US gallons?

I can get 25MPG on a long run comfortably, but I run LPG now so I actually get the cost equivalent of 38MPG :)

500 is easy to achieve on the highway; as long as you are not in a hurry. Although my best is about 530, I can seldon drive slow enough to achieve this if I am traveling that far.

After all, you are talking about a difference of about an hour and a half. I'd rather have that 1.5 hours than the extra $12 - $15 dollars in the pocket.

I get far better mileage when using Premium Gas... and I can get about 23.5 MPG in my 4.4 @ about 65 (no higher) mph.

Agreed. I have no patience for this.

Fwiw, that '568' I got was on regular gas, lil' to no A/C until we got close to our NJ destination, (where that pic was taken), and we were
not gramps driving: eg 630 miles in 10.5 hrs, including Balto Tunnel and NJ traffic. The nearly worn out B Stone Turanzas helped too, imo...
I've never come close again with the replacement Mich Diamaris, which suck, imo.

While I'm inclined to agree, i believe my statement was assuming that you've already chosen your vehicle. Such as an X5. It's no Jaguar E-Type but for any of us comparing our numbers, the aerodynamics of an E53 is a wash as that is a constant. The variables are more what I was alluding to.

Ha, I'm lucky to get 300 a tank in the 4.6.

Just did 15.68 on the way to cali with 5400lbs on the trailer!

San Diego to Las Vegas, We do this trip 3 times a year. The X5 3.0i gets about 24mpg going out there. I just set it at 80mph all the way. The trip is about 350 miles one way, it take less than half the tank.

My 4.4i at best does 23mpg, but I feel like Im driving like a grandpa, my average is 20-21mpg. And that is still gentle driving where I never rev over 2000rpm unless for safety.

I've just done road trip 1200km's, 150 lts and averaged 10.6 lts/100km, about 22 MPG (USgal). avg speed 99.9 kms our open rd speed limit 100kms & fuel @ $2.25/lt thats about $8us/gal, 2001 4.4 130k, chipped to 285 kw.
Was good to get out of our earthquake ratted town for the weekend, the X is great for getting round out very badly munted streets here in Christchurch NZ

(1) I don't live in an area where long drives are possible.

(2) I don't live in an area where gas is more pure. (depending on your climate gas stations add several additives to the gas).

On a 425 mile trip from San Francisco to Los Angeles area via HWY 5 @65 MPH, I got an indicated range of 585 AFTER having driven 100 miles. I know how the range meter fluctuates, but made the trip with 3/8 tank left. Calculations tell me if I continued, I can almost approach +/-680 miles per tank. This is with one passenger with light luggage. I literally drive like a grandma :nanana:

How is that even possible lol not over 2000 rpms dude your going slowwwwww lol nice car though

I drive that route many times a year but to San Diego. How do you drive 65 on I5 and NOT get run over by semis? :wow: Traffic flows at between 75 -80. As long as you are following traffic and not cutting in and out, the CHP won't usually bother you. I'm usually at around 80, lightly loaded, and get 19+ mpg. Do you have an I6 or diesel and live in SF? If so, I seriously doubt if you can come close 27 mpg's from an X unless you are going 45mph on the freeway. Not too worried about mileage as I didn't get a V8 for mileage but if I drove 70 (posted speed limit) I'd probably get 21-22 mpg. In town, city driving in SF with the hills, 15......:dunno:

I'm driving an '02 3.0i. All I can say it was VERY stressful! I was purposely trying to squeeze every mile of the tank; 27 MPG :wow:. Going south in the middle of the night helps because all the semis are going north. They're usually traveling slightly less than 65, so I have to plan every move and adjust speed to pass before the person going 80+ in the left lane catches up. When I go back north, I take 101 because there's just a lot less traffic after Santa Barbara. I just set it to 65 and cruise all the way back.

As for SF, I also get about 15 MPG. I don't think there's a completely leveled street in SF :rofl:. I live near Lake Merced and getting onto the freeway is a breeze for me. I also commute to Santa Cruz (75 miles), going on the 101/85/17, best I can get is 23.5 MPG, also while trying to squeeze every mile out.

I recently did a 100 mile round trip to Ewing, NJ, and was only able to get 21 MPG round trip. This did include 80 miles drafting semis at 65 MPH and the rest of of the mileage doing local driving. I'm very disappointed at what this truck gets; the best I've seen was 22 MPG on a 1000 mile trip doing all highway.

Yea, going 65 in I5 is very stressful. We just bought a house 1 block off lake Merced. We are currently remodeling and should be done in 2 months.

dskyers,

I know where your coming from, but its very possible and quite a relaxing drive also not to mention the fuel savings. If I drive perkier than that I'm wasting petrol as I drive mostly in busy traffic with a lot of stop starting. I don't know which engine you have but with the V8 I find the torque drives the car for me, I drive at speed and get to it fast enough without anyone swearing or overtaking me. Don't get me wrong though, after a hard days work when entering the highway I get the engine to remind me why I love it so much! :thumbup:

I took a trip to Boston from Morris County, NJ, a ~600 mi trip. We averaged 22.1 MPG there until Boston's city driving dropped the MPG to 20.2. We had to fill up on the way back(93 costs $4.43!) on the border of Massachusetts and made the rest of the way back getting 22.8 MPG while doing around 70 MPH the whole way.

It isn't horrible but I sometimes wish I could get 20+ MPG without needing to watch the OBC. I bet I could have done this whole trip in a Civic not watching my speed and still get 25+ MPG.

But it's still a Civic. Almost any 4 cylinder car should get 25+ on the freeway. Heck, our V-8 SL gets 24+ on the freeway doing 80. I actually got into my in-law's Civic yesterday and then it all came back to me...This is the reason why we moved to German cars. The Civic has no character or soul. It's also not very engaging to drive. It's economical but your basic transportation.

What model X?

3.0i engine.

I haven't driven a Civic before but I guess it won't be that engaging to drive. However, I don't think this X5 is very exciting either.

Must not have been an SI. One of my other rides!

Spend more time behind the wheels of the cars I've driven (Accord, Camry, Maxima) and you'd agree! Sure it's no Boxster, but for a SUV it is suprisingly fun.

No, not an SI but an LX. There are a lot of nice ricer SI's in the Bay Area and most are driven by kids who want to race you all the time. I've always owned Japanese cars...until I started in on German cars. The cars just drive and feel totally different. As I said, for me, most Japanese cars are very reliable but not as engaging or have as much soul. Granted the German cars cost more to maintain, but in the end, I think it's worth it. I don't mod so all my cars are stock. I don't usually race but it's funny when an unmodded SI pulls up and wants to run me in the M5.

Ever drive an X5 with either the 4.4 or 4.8? They are totally different animals from a 3.0. Try one and you will see and feel the difference.

Never tried a V8 E53. My mother's X6 35i is what I consider "fast" even if many cars on the road can keep up with it. I drove my father's 325xi once too and found much more pep in that than the X5.

It is possible that it would be more fun with a V8 X5 as I won't ever be lacking power again. Downshifting up an incline to keep a steady 75 MPH sucks! However, it would never be justifiable to move from an I6 E53 to a V8 E53 so I will keep using what I have.

Going to try some hypermiling this week with the X and see what happens. :)

I used to do a bit of hypermiling in my Hondas I've owned but never thought to try in the X. Might be entertaining on a "not in a hurry" road trip.. What psi are you guys running? 40? 45? Guessing weight savings in this beast is pointless...

PSI?

psi - imperial measurement for tire pressure

Ive done it, 300+ something KM, i hate miles and refuse to use them or inches or anything like that

Ahh... not sure, I always inflate to whatever it says on the door. I think it's 32 front and 35 rear, but I'd have to look. One mechanic I know says that you can give it 3-4 more safely, but not sure if he's off his rocker. ;)
