Thank you for the info - I was letting it go 7500 as a compromise, but it seems the price dropped a little and I'm ok with 5k intervals. It's not like the oil change takes long to do - I can do it in 30 minutes and I let it drip until it has practically stopped dripping out. :thumbup:There's been some message traffic about this on one of the MINI forums. Apparently Mobil 1 0W40 has recently been re-formulated, and lost its "long life" certification from BMW. According to what I've read, all that means is that BMW won't 'approve' it for it's 10,000- or 15,000-mile oil change interval. But if you (like many of us) have switched to a more frequent oil change interval (say 5,000 miles), the new formulation should be fine in your engine.
