Re: castrol 0W30 synt oil change once every year.
We were told from the dealer and it says the same in the manual, with the last two Mercedes, to change the oil every 12-15k miles.
Of course, the W210 cars have a 10qt capacity.
I wonder if it's done for environmental reasons, plus don't the new MINIs have start/stop? That reduces wear by quite a bit as well.
