Where do I go to change my car's engine oil besides the dealership/ on 2007 Mercedes-Benz S550

My 2007 S550 has just turned 37,000 miles and is going to
require an oil change. Are all synthetic oils the same?
What company provides the best synthetic oil change offer
in this area?

All Synthetics are not the same. Different cars require different specs. However, any reputible shop can service your Mercedes.
