I'd like a little insight from the forum. Is there any reason that a standard oil change can't be performed by one of the quick lube type places? Up to this point, I've had them done by a high dollar Mercedes service center, but given that I specify synthetic oil and the proper filter, I don't know why I couldn't go for the faster, cheaper option. Does anyone know of any "special requirements" that an E320 has which the quick lube places wouldn't know about? Thanks.
