1)Yes you're right, but the new oil i put in it performs the same as the old 10K oil (I used to use motul 300V on my MR2 roadster and it definitely give me something that i would like to see e.g performance and MPG)
2)And my engine has done less than 25K miles and checked by BMW regularly & maintain to its highest standard, so there must be something wrong with the ingredients of the oil.
3)the price i compared were all 100% sythetic oil.
The thing i'm trying to say here is mobil 1 is no good for the price u paid and i think other manufacturers got better oil with lower prices.

1. why should the engine run smoother - its a lubricant, not a noise insulator or balance shaft.
2. surely thats a function of your car, polluting the oil, not the oil itself.
3. perhaps because its good quality?
years ago, i took a turbo to be examined. the guy in the shop (turbo technics in northampton) showed me a turbo that had a conventional oil damage it though deposits blocking up oil holes. he reccomended mobil one as it doesnt cause this kinda damage.
oil consumption - my 520d hasnt had a top up in 33k. On the other hand, ive had GM brand cars in the past where the owners manual stated 500 miles per pint would be normal!

2)Do you know what cause it? Better get my bimmer check over! But funny enough i didn't find any sludge inside the engine after a fully flush with 7L of chemeical before they put new one in.
3)i doubt it
(I didn't say mobil 1 will harm ur engine or anything bad but it's just not worth that price tag and definitely will try something etc next time) Have used Motul 330v ,Gastrol and fuchs in the past and never have a compliant with it.
Seems loads of mobil 1 fans here
Would interested to hear what you like it about

I had to add a quart of oil to my 2008 550i after about 6K miles of fairly spirited driving. I used Castrol full synthetic which was referenced in the manual or under the hood. Can't remember which
