I've been a bit MIA here, as work has kept me quite busy.
I have to ask ,how does one expect another xxx miles from an engine?
Easy: based on how well it has run during the previous X miles, except for a catastrophic failure, I expect it to run another X miles. I'm sure wear is occurring, as with all engines, but in my experience the rate of wear in diesels tends to taper off as the miles increase.
How do you enjoy the X3 compared to the GLK?
I'm enjoying it immensely. Both are now tuned, pushing 250hp and 450 ft-lbs tq, returning mid-30s mpg, and have not given me any trouble. The X3d feels much lighter on its feet and agile, better balanced, better gearing and better fuel economy. The engine runs beautifully, very quiet for a diesel (probably due to the aluminum block) and since it's the lower mileage vehicle of the 2 we have, I tend to drive it everywhere.
I just threw out the RFT Pirellis that were unevenly worn and badly out of round with Kumho Ecsta PA51 non-RFT and I have to say, what a difference in comfort and handling. I ditched the RFTs on the GLK long ago, was determined to do the same for the X3d. I'm not worried about flats, as I have AAA and BMW Roadside.
@mosschops, that is an excellent UOA. I plan to switch the Bluetec over to PP Euro L as well, next change. All I need to do is buy a filter pack.
