Hi there!
I bought a 2011 e550 last year. I love this car. It gets up and moves!
lately the MPG and power have been going down. Any suggestions would be appreciated.
thanks!
Joe.

Loss of power could be injectors to spark plugs. The older the plugs are the wider the gap is. I used BG 44k for injector maintenance, its very concentrated so use caution pouring it in. Use glove to protect your skin. Also your fuel filter may be getting plugged up. I just changed plugs oil on my 13'SLS and that really helped.

Pretty much what BenzBopper said, also have you serviced the car since you've owned it? I would also try some Injector cleaner as well... I've seen a few members talk about Chevron Techron Injector cleaner. Do the plugs, oil, injector cleaner, fuel filter, and maybe a good old Italian tune-up.
