Consumption for the Z4 3.0si [UPDATE]

Hello forum,

A couple of days ago I posted something about my car having very high consumption. After close examination I was able to determine the issue. Fortunately it is not a VANOS failure but this problem is most common in BMW engines bigger than 2.5l (and has been reported also in other cars with similar engine builds). It's a syndrome called "grave pede", most commonly known as "heavy foot". After "slight" modifications of my driving style I realized that I too can get 35-40 mpg with my Zed.

Love you all for your support and the paranoia I went through with regards to VANOS failure and other problems.

Regards,
Alex

Feel you've got it completely wrong alexstr. You're driving style was'nt 'grave pedel' but 'natural fun' or 'all day hooning'. The style you're describing now is 'old lady Sunday morning'. There are some other less polite alternatives available, often shouted by the driver stuck behind. Respectfully suggest you dismiss measuring mpg and focus solely on spm - smiles per mile. If you want mpg, buy a Prius. I'd stick with your Zed.

(glad it wasn't VANOS failure).
 
My computer tells me I averaged 28mpg on my last hoon :)

Good going I say :thumbsup:

Enjoy

Mine is stuck on 25.9 mpg - lots of local taxi driving of Wee Bing to his social engagements, and then getting 'lost' on the way home, are not helping. I am feeling ashamed and am determined to get it lower - I have recently re-discovered the firmer inch of throttle on my auto that results in an extra kick-down and loudness regardless of speed... This will help I think.

Think we should qualify this. You could get sub 20mpg in London rush hour on a Friday afternoon...

Not happened to me so far - think the lowest I have had is 23, and I have done a fair few slow London / M25 commutes. You're right though. The OBC should be re-set prior to a non-commute hoon to qualify for consideration (of course commute hoon is a bit of an oxymoron, but you now what I mean :P ). Pic of recorded MPG post-hoon required, and perhaps the average MPH shoud be re-set prior as well to demonstrate Hoon Intensity :lol:

The lowest i went was: 22.4 Litres/100km = 13 MPG, on a road through a forest, freshly paved, a lot of turns, I only used 2nd and 3rd gear, the car loved it! (so did i!!!)

I find my Z4 3.0 manual to be very eco. Regularly gets around 8.3L/100km (34mpg), worst I've had is 10.2L/100km (~28mpg).

Besides, BMWs are more eco than Priuses: www.youtube.com/watch?v=Tpc0vjAx2gs&t=41
