DD is right about DPS and sanjsanj should try to do a manual check by filling up and ........... and yes it is a diesel.

 

14.6 gallons here 545i is this guy serious ? he must ov swapped a bseries dohc vtec honda motor lol

 

1. Buy a diesel

2. Use UK gallons which are larger than US gallons.

But like I said, these figures are not representative a 525D would normally get around 38-45mpg as a long term average.

 

First of all you need to get yourself a diesel engine. Second, and this must be true for the OP, your daily drive must not involve too much urban driving (otherwise there's no way he's getting 70mpg). Third, you need to be using British gallons rather than American gallons. They're bigger. A British gallon is 4.5 Litres of petrol, whereas an American gallon is 3.75 Liters of gasoline. So you can divide any British MPG figure by 1.2 right away. That means his 70 (UK) MPG is actually 58.33 (US) MPG.

 

That means you would win the race from Basel to Blackpool and the Stig wouldn't have a chance to turn on the lights!

 

Sadly to say the concept of Diesels really suck in the US. The end cost for the car it a lot more, and you pay dearly for the fuel! E.G. A few days ago, regular was 3.08 and diesel was 3.94! There goes any savings you thought you were getting...

 

The cars end up costing more in europe too. What's different in Germany at least though, is that diesel is cheaper (but by only about 5%).

It's nowhere near as clear cut as the pro diesel camp would want to believe. I think diesel is more expensive than petrol in the UK too. Add to that a more on-the-edge engine (adding two turbos, swirl flaps, particle filters etc) results in a higher risk of expensive repairs. The fact that the car will cost more, the car tax I believe costs more, the fuel costs more (except in Germany), and the best fuel economy comes when the car is running warm/hot.

You need to weigh up the number of miles you're going to be driving and therefore the amount of fuel you'd be buying, and factor that into the purchase while comparing the price of the diesel car vs a similar spec petrol car. I only drive 9,000 miles a year, so I'd have trouble getting a diesel to pay for itself. Plus, living in Germany with the autobahns, I'd be disappointed with the diesel's lack of power above about 80mph. A 535d takes about twice as long to get from 80mph to 150mph than a 545i does. From 10mph to 40mph there's very little in it, but up high the difference is huge.

 

Ha, right. i was stoked when my MPG hit 20.1 for a minute. way to ruin our cute american christmas!

 

... If I had a full tank, this would've been a lot more impressive.
Image Quality is crap, be forewarned.

 

what is this. . .
Youare kidding right. Can't in my life imagine getting 30mpg out of my 3 litter engine .
What do I need to do to get to where you are on gas mileage ?
Seriously man, this is crazy
