Hello, Just bought a new 335i with sport pack. Love it! The manual does not give any info on oil changes. I want to do it myself. When the car has 1000 miles on it I want to change the oil. Do they assume that everyone takes their cars to the dealer for everything? How much oil does it take with filter? The service is included for 4 years, but I don't want to wait until the computer says I need oil. The manual really disappointed me. I am used to Porsche manuals, where they give us more credit as car guys to be able to do simple things like change oil. Any thoughts?
