BMW maintenance schedule
Just wanted opinion on the BMW service and maintenance schedule. I have been told that you should ignore the cars service interval and carryout 12 monthly oil changes regardless. Our x5 drives only 8,000 kms a year so it would be over 2 years between oil services if we go by the cars display......seems like a very long time particularly for a diesel engine. We have also been told that the long life castrol engine oil that BMW specifies is designed for extended service intervals and no other oil should be used. My car is the twin turbo 3.0sd.
