Topic: E39 real world economy Posted: 18-February-2004 at 20:59 |
Just got meself a 1997 528i SE. The owners manual and various websites (Parkers) indicate that extra urban MPG is about 38 (optimistic?!), urban is 21 and combined is 29. Any ideas what the real world economy is for someone who knows where the accelerator is? Figures for extra urban, urban and combined would be appreciated or a weblink to somewhere that has them for UK 528i's. Stone 91 525i SE man (any takers?) 97 528i SE man |

We have a e39 528 (99) model. We have had as much as 37MPG driving very carefully at around 50-70 on the motorway. We have had 26mpg as the worst we have ever achieved and generally get between 29-31mpg with a mixed driving of town and motorway. When we first got it we drove to Barcelona in August crusing at around the ton mark for 16 hours and achieved 33mpg 5 up with the air con on. Best info i can give you i'm afraid |

Thanks Sohlman, that'll do nicely. It sounds considerably better than my E34 525i which does ~28 mpg on the motorway and ~22 on 'normal' commuting in town and twisty country roads. I have to rev the 525i hard to get it to fly and the mpg gauge heads so far right it hurts! Cheers Stone 91 525i SE man 97 528i SE man |

The E39 is lighter and is possibly (certainly looks it!) more aerodynamic than the E34, so I would expect it to better the E34's fuel economy based on that alone. Secondly, the larger sixes seem to give higher MPGs than the smaller ones so that too will contribute to better fuel economy. I know that if the time comes that I replace my E34 with an E39, I wouldn't want anything less than a 528.

You also need to bear in mind the improvements of the later engines and also to the DME engine management system improvements which will also return better MPG over earlier cars

Currently getting 23. something MPG on an urbanish work run over 150 miles or so. Thats driving restrained as well. Have yet to give it a proper open road test as I've been away. Will get a chance next month with a (ahem legal) blast down a few M Ways. I have to admit I was expecting better MPG from a newer car with a better DME. My tyres are Pirelli 225 16"s with plenty of meat left. Fellie - nice pic of your motor. Mine has a few less toys and no angel eyes (yet) but it's a manual which is the bit I like . Stone |

hoping to get a few more pics soon, that is the one that tempted me to my car lol, ( the autotrader advert pic ) im getting ave. of 23 also now, but on a 50 mile run recently, it was ave. around 42 at a steady 70-90, cant argue with that, due service to soon :o/ are your tyres an aquatred type? ( v pattern as oppsed to lots of lines around tyre :))) friend of mine with a 523 99 just changed all 4 to rain pattern/ aquatread affairs, lost about 4mpg he reckons ( thought id explain the situ there a little better :))) good run does em loads of good Stone, find an excuse, take offa while |

Still not done a long blast yet but after adjusting pressures and another 40 miles I'm getting 22. something on the same run! That's no better than my old 525i with the same tyres. Oh well. Current tyres are all P6000's. Some marketing waffle and a picture can be found here: http://www.tirerack.com/tires/tires.jsp?tireMake=Pirelli&tireModel=P6000 Anyone got any other suggestions for tyres with reasonable performance and economy? Good to hear Ian's getting over 30mpg but I'm too attached to the 528's pulling power to give it up Stone |

I filled up my 2001 520i 2.2 manual last week with Shell Optimax, reset the OBC then drove the 18 miles to work in London City and back again - 21.2 MPG Didn't think tyres would make a huge amount of difference to fuel consumption - mine are pretty worn Dunlop SP Sport 01s. |

Had my 528 Glacier green manual, for two years now, running on bf goodrich 225 60 15 tyres and getting 34 on a run or 24 around town. Upgrading to 17 m5 wheels this week. My rear tyres are only lasting about 8k ( heavy left foot ). Anyone interested in clear lenses upgrade German and Sweedish £175 & VAT. Hope that this helps ? |

best way to calucalte is like this -
fill the car to the brim - reset the trip and drive for 100 miles. go back to same garage and refill to the brim again. note now much money the refill costs. now you know how much it costs to drive 100 miles!! way better than those mpg readout thingies!! |

Eamo - reckon you're right there. But, most pumps tell you how many litres they deliver so I don't need to worry about going back to the same garage. Unless, unless you're suggesting UK fuel quality varies more than it should?! Petrol gauge seems to sink pretty quick so I suspect the mpg readout isn't far wrong. Stone |

the reason I would go back to the same garage is that the price per litre will be the same. if you went to another garage the price of the petrol could be dearer/cheaper and therfore not give you a clearer picture. |

Agreed, but I'm interested in miles per gallon, and as I can get the number of litres from the pump readouts, the price isn't such a worry. Cheers Stone |

As an experiment, I tried to see what I could get out of my 530i E39. With 600 miles since its first service I have averaged 30.3 and and on one 35 mile trip (a warm engine) I got 40.3 with some very carefull cruising at 60 mph. Not bad eh?

Spike You must be driving down 35 mile long hills. I couldn't get 40 mpg if I was on the back of a RAC lorry Just bought a pair of 540 sport alloys with toyo tyres so I wonder if my mpg will go down 255 on the back !!

Well it was very carefull driving. Cruise control on just about the whole time. Also using optimax so that may give it the edge. Also not sure how accurate the computer is. More typical consumption is around 30 with gentle driving on the motorways and low twenties around town. Really depends on how you drive it. Sure I could get high teens if I really enjoyed myself!

In my experience the computer can be a little bit optomistic when it comes to fuel consumpsion. It is on my car anyway, generally between 2 and 3 mpg better than actual. |
