2011 BMW X5 35i ... Gas Mileage?

True enough; however, my X35d mpg also declines noticeably in cold weather as well.

Nobody talks about adblue. On the X5 diesel, after a few years, like when the warranty expires, you will have to face the adblue fill up. Do the math and you will see that you will be paying more in the long run for the X5 diesel. The X5 diesel is deceiving when we talk about mpg. For now, with todays fuel prices, you are best off driving the X5 petrol. I personally love diesels and will probably purchase one this fall.

We've all been talking about adblue, or AUS32 as it is commonly called.

$16 a gallon, about 1000 miles per gallon,.... So add 1.5 cents per mile. (My original fill of 6.5 gallons has lasted 9000 miles so far, and no warnings yet...)

The cost is incredibly reasonable- and manageable...unless you are going to pay the BMW dealer $250 to do a pointless DEF 'service' when all you need is to dump a few gallons in....


The fluid is sold at virtually every truck stop across america, and is used every day by long haul truckers. Nothing esoteric or expensive about it...

16.00/gallon. Sounds reasonable. I do know that truck stops have a similar urea solution concentration but I did NOT know that it could be used on the X5 diesel. Good to know. Thats one of the reasons why I will not be purchasing a Q7 TDI. The Audi Q7 is not customer friendly. Only the dealer can reset the the adblue sensor. Funny thing is that the adblue fill up location is conveniently located next to the diesel fill up. Customer friendly you might think, however...in an emergency, you are able to dispense enough adblue to get you to the dealer so that the dealer can fill up the ten gallon tank. If you were to fill up the adblue(urea) tank yourself the computer will not recognize it. This is very inconvenient yet they will argue that purchasing the Audi care service plan for 740.00(45,000 miles) will save you a lot of money. Audi care service plan covers oil changes and adblue. I asked Audi the same question "What happens when the Audi Care Service plan expires?". I also worked out a calculation that showed how deceiving their advertisement for best mpg when comparing their TDI to their own GAS and competitor GAS vehicles. Got to go on the elliptical. Be back in a few....

Yes, and I have seen projections that indicate the price of DEF will fall to below $5 a gallon once its use in over the road semis becomes widespread in the next few years.

Here's one source of that projection:

Of course, if one insists on buying it from BMW, you can multiply that price several fold.


Here the Cummins DEF:

This is exactly what I'm seriously considering since the trade-offs in going diesel (filling issues, froze DEF, etc) could be outweighed by only a slightly higher operating cost. In Toronto, it's a little more difficult to justify since diesel is cheaper that premium gas by $0.15 to $0.25 per *litre*. What makes me wonder is why the USA EPA numbers are so far off of the Canadian/EU numbers. Is the EPA testing procedures biased towards gas?

The EPA underestimates diesel efficiency in its tests. Real world results of diesel engines are materially higher than the EPA sticker numbers. So the 2mpg difference isn't a real. I routinely get 23-24mpg in city driving for 35d. On highway, always +30mpg.

Just about the same. I get 22 city and 29 hwy.

I received my 35i yesterday (woohoo!). However, the gas mileage is a little disappointing. I hardly get 13 mpg!
