I'd go straight to the general manager. What a crock of kaka. And on another note, I've never understood people who go with synthetic to lenghten the change interval. To each his own, but I have never changed the interval nor would I. I think M1 is ok, certainly not a superior oil, but better than dino. If you go synthetic, change your oil through the standard intervals. Even Amsoil says to change sooner than 7500 under certain conditions. A car is not worth being cheap on, imo.

 

that's what i do.

i use Mobil 1 5w-30 all the time and i get oil changed every 3750miles. no buts no excuses.

This is really strange. From where I came from, not a 3rd world, synthetic oil lasts for at least 10k km, that's at least 7k miles. BMWs have their oil changed at 15k Km, about 10k miles.

BMW/Merc uses much more oil and a sump filtering system, cannot be compared to our system. My oil (m1) usually looks fine on the report, but you start getting high insoluables which is filtration.
