Frustrated over the diesel fuel situation!
I have only owned my Diesel BMW (2012 X5 xDrive, 35d) for a few weeks. She was very quiet during the test drive and on the way home, a drive about 22 miles.
However I then noticed that the vehicle began to sound more and more like a diesel of old
(300 miles). Then came the first experience in filling the tank at a local Shell station very near to my home. First, the nossle bearly fit in the fill for tank and the engine sounded even louder after another 100 mile. The pump was labeled correctly (ULSD) so I have a feeling that the cetane levels were really low. I would think that the real issue is, there is no requirement to post the cetane rating although the engine requires more.
The question remains, where can we buy quality diesel fuel that will end this debate??????
By the way, I did go back to the BMW dealer and ask the same question concerning cetane levels, no valid answer other than ULSD.
