Which of these engine oils is best for the 2007 S550?
1. Pennzoil Ultra Euro 5W-40 Full Synthetic
or
2. Mobil 1 0W-40 Full Synthetic

both makers claim that their product is MB approved!

Also, what type of brake fluid and power stearing fluid should I use?

Mobil 1 is a far superior engine oil and has been around forever. As far as the weight you listed, I recommend referring to the owner's manual for the best selection for where you live (temps). Always use Mercedes benz fluid for the transmission and power steering, they are special.

Please let us know happens so it will help others.

Best, Ken
