535 and 525i fuel economy

[dallas1993]

I was just wondering what kind of fuel economy a bmw 525 535i gets. i have a 540i right now and its quite expensive cause its a v8. so if someone could tell me that would be great thanks.

for starters

and a 535 will probably get less mpg than a 540

MPG: M50 525i>540i>M20 525i>535i

MPG: M50 525i>540i>M20 525i>535i
I'd switch the M20 in front of the M50. Best MPG car I've had.

[strad]

My M30 sucks down fuel like there's no tomorrow. But I love it anyways :)

16 mpg city, 21 mpg hwy.

[MK2MR2]

I get 25 c/d in my M20 car and Im not exactly driving like a granny.

[Happy Hooligan]

just drove to vegas from LA and averaged about 29-30 in a 525i doing just over 70 the whole way.

you've never had an M50 I take it?; even the EPA rates the M50 at 1-4 mpg better than the M20......and it makes more power.

215k miles touring, and 15-18 mpgc 24-28 mpgh

after my Miller MAF + W.A.R. chip conversion i went from 16 to 17mpg city :laugh

[Dumpy525i]

for mpg i miss my 4cyl 240sx.

38 on the highway crusin/~30 city not beating on it... :)

Never owned an M50 eh?

My 1992 M50 525i:

19-23mpg around town if I RAPE my car.
21-25mpg around town driving nice
30mpg+ on the freeway.

My M20 cars never got close to that.

I don't know how you guys got 30+ mpg on the M50 525i unless you were doing it in a manual, because both our auto M50s were getting 25-28mpg on the freeway AT MOST running completely stock. City mileage seems to vary from 17-22 depending on what 'city' is to you (hills, lots of stop go vs long stretched 'city' roads).

As for my 535i/5, if I baby it on the freeway I will get ~21mpg, while city is 15-17mpg.

[JMI]

My '89 535i with Auto gets 14-15 city and 24-26 highway.

not stock but is manual
bosch design 3s, fan delete, 195 tyres at high pressure and a slightly shorter diff makes me account to my good economy (not motorway cruising)
effectively i can shift to 5th at 30 or below, i cant remember how low and car still pulls cleanly, all be it slowly at low throttle
i suspect my motorway cruising is slightly penalised due to the diff but i get the feeling it compensates for high gears and low speed. OBC reads an average speed of 24 lol... i rarely get to sit at speed on motorways for more than 5 minutes on my daily commute.

[brettholomew21]

My 535i/5 gets about 20-21 in mixed driving. On my drive to Houston from Denver I was averaging about 25-26. I'd bet it'd do about 18 in straight up city driving.

[clay1]

My computer says I average 22 with almost all city driving. Highway I can sustain 38

[BoldUlysses]

OBC sez ~24 mpg overall. Reset it on the highway and it stays around 28-29 mpg. 205/65-15s, bone stock.

[KyleCleveland]

I'll just put it out there that I hate all of you. I average about 16 mpg for a tank. I drive mostly in town.

[JesterMX6]

as an m30 owner who drives the crap out of his vehicle, if you're getting less than 16mpg city its time for a tuneup. i never drive in 4th. rarely shift before 3500rpm and my gas pedal might as well be an on/.5/off switch. because those are the only three positions that exist. and i still manage to get 16 out of it until i got the MAF kit. now 17mpg.

it'll be interesting to see if i can maintain that when i get my turbo installed :laugh

[Hodge]

I was getting 14 or 15mpg in the M50NV auto, but after SeaFoaming this past week it shot up to 17+mpg....this is all city btw.

I drive to school and home which is about 20 miles in city total, then to work which is about 2 miles to and from. So I usually drive 24 miles in a day. I'd say 17 isn't too bad since I only get to open it up to 55mph for about 6 of the 24 miles on my commute.

I am going to take a small trip tomorrow and will reset to see what I average on the interstate. I will try to keep it around 75mph and see what happens.

[KyleCleveland]

I think my issue stems from 90% of my drives are to work, which is 2 miles away. By the time the car gets to its warmed up temperature I'm shutting it off. It is never running efficiently.

And besides that, whenever it's warmed up I can't help but put my foot to the floor. I also have a 3.15LSD so that is probably mucking up the OBC calculations a bit.

Lots of variables are adding up to shitty mileage. The OBC says I get about 21-22 on highway or about 25 on the instant mpg gauge while cruising.

I hear that.

My last road trip netted 22 MPG (162 miles) with about 90% highway at about 75 to 80 MPH.

[Happy Hooligan]

Like I said before I got right about 30 the whole way to vegas from LA, but in town I get 13-14.

makes no odds, milage is calcualted by injector pulses and road speed sensor, fitted to the diff. Tyre sizes and different injector sizes can throw it off

[KyleCleveland]

Where is the road speed sensor located? Isn't it on the input side of the differential?

[uk525td]

i assume its on the output, at least thats my understanding.
i guess if it were on the input they would have saved some cabling and put it on the gbox output ?

looks like its on the output in the diagram

Non-vanos 5 speed with a chip...if I lock the cruise on 70-80 and just roll, it will pull anywhere from 30-36mpg. If I really watch the eco gauge, I can get over 25 around town, but that really takes some effort. (these are all math at the pump figures FYI...not OBC readings.)

[marsmann]

Driving styles, gas, location (hills or not), mechanical condition of car, mods, wheel sizes, weight (such as speaker boxes, people), etc. will give all of you the varying results/numbers you see.

Me:

92 535i bone stock with new tires on factory wheels:

17-21 Mixed
25-26 Highway

[E34 525]

I get on average around 25 mpg in my 525i I still have very low Km's though, (42,000KM) :D

[SimmBimma11212]

From home to school upstate is like 240-250 miles and if i fill up at home, it only uses half tank.

[E34ührer]

An M50 525i getting 25mpg's is pretty standard. My car has 265541.76KM's on it, and it gets more than 25 if you watch it.

LAME!

Sometimes i would like to have an m50 just for the sake of better fuel economy. The m30 loves to down the fuel.

[70383roadrunner]

My M30 sucks down fuel like there's no tomorrow. But I love it anyways :)

16 mpg city, 21 mpg hwy.
