That's some awesome mileage for the X5d. Best I've had to date is 27MPG on a highway trip. I'm typically running 22-24MPG in daily driving, figured by hand and the on-board computer. The extent of freeway vs local driving seems to decide the 22 vs 24 MPG figure.

Cetane ratings

Has anyone compared different cetane levels and the general impact on cost over performance? I have compared Octane on all my regular gas vehicles and invariably get better Dollar for Dollar with 87 and an occasional STP over 93. I realize most of this is impacted by the true product being delivered from the distributor and that is often suspect as law requires an average minimum and most of these local retailers use the same products regardless.

I recognize performance impacts and warranty disclaimers and such, but outside my play toy cars could never see enough difference or care enough over the $1k/yr saved.

Dealer suggests 45 USLD. Most local stations like HESS offer 40, wondering if it pays to care...

Thanks

I run premium diesel with a cetane rating 49-51. BMW wants us to run a minimum 51 cetane, but I can't find anything higher around here. They also don't want us to run additives...

I can tell the difference between regular and premium diesel. My engine runs smoother on premium diesel. The only regular diesel tank of fuel was from the dealer...

Where can I find premium diesel in bay area? I can only see diesel#2. I'm getting 23.8mpg city, and about 29-30mpg on highway. sounds right?

I live in the SF bay area and have not been able to find anything but the diesel #2. If anyone knows of premium diesel in this area, please let me know. I use Shell and I get about 32 or so on the highway and 18-19 in town. I do a lot of short, stop and go town driving. I drove about 120 miles over the weekend some open freeway, some heavy city traffic. the overall mpg was 26.1. My x5 is a 2010 oct/nov build.

On a related note, I haven't been able to find out if we get winter diesel in this area. When I go up to Tahoe I have to time the gas ups so I add at least a quarter tank as soon as I get up there (in winter.) If anyone knows about winter diesel situation in the SF bay area, I'd like to know.

Does anyone know why NJ (route 22 area) gas stations are not posting cetane levels. The few I have found are only 40 (Hess and Getty). Some other name brands (Shell, BP, Sunoco) use the term premium, but have no rating on the pump.

I thought they were obligated by law to post similar to octane.

Thanks

Nope, the law only applies to gasoline.

In the US, our diesel currently doesn't have to meet the same restrictions and regulations that Europeans have to deal with. Majority of our diesel has been for trucking engines, and long cycles of cheap gas until recently has kept diesel in the background. The opposite is true in Europe where high gas prices have forced diesel engines in all forms along with smaller gasoline engines/cars to become much more viable. I'm sure that will change here over time as americans are realizing the gains from cleaner more fuel efficient diesels.

Just curious, when you first bought your '09 used, what did the average mpg reading state? I'm getting 23 mpg for overall driving, but I do drive fast

I'm getting 23-24 mixed. I did see 29 on a long freeway trip. I'm hoping to see better as my X5 only has 1300 miles on it.
