Being a tech, I have to agree with MB DOC, If you just do one oil change between the recommended service interval, you will help to prevent major engine work in the future. The reason for the FSS is that Mercedes had a survey done and the highest complaint among owners was cost of service. So what did they do? Spent millions to come up with a mechanism that reminds you to do it at about 10,000 mile intervals.
