Hello all,

I am debating whether to change the motor oil every 5K miles. Currently, the dealer will replace the oil after the OBC informs me that a flush is needed...I bought the full maintenance package which covers oil changes during the first 100K miles.

Also, any suggestions on when I should replace the "lifetime" transmission fluid. I am thinking about changing at 60K. It is my understanding that this procedure is very complicated. Is this true? I have access to a good indy who I use for my SUV (i.e., Autobahn of Towson).

I drive the e39 twice a week. However, I am a spirited driver. There are 55K miles on the clock, and I would love to keep this vehicle forever! Thanks.
