Some changes I've made, that differ from Mercedes Benz recommendations:
I don't believe in multi-grade motor oil. I've driven air-cooled VW's for too many years. A straight-weight motor oil will stand up to hard use and high temperatures much better than a multi-grade oil. Think about it, a 10W-30 oil is actually a 10W oil!
I also prefer to use a lighter weight oil in the air cleaner, since it will cut down on the amount of vacuum required to pull the air through the air cleaner.
I like to check my transmission oil almost as often as I do the engine oil. (Once bitten....) If a Unimog transmission output seal leaks, it doesn't show externally. It leaks down the inside of the drive-shaft tube, and over-fills the differential.
