Undercarriage cover question and GLS 550 question
Anyway, does anyone know if the 550 engine is the same as the AMG V8? They look very similar in design. Other thing I hate is the eco mode auto start-stop thing which I cannot understand why I would want my car to stop for half a second as I'm waiting to make a turn. I'm looking at a hack from Vladimir on ebay that can reprogram it easily through the OBD port: https://www.ebay.com/itm/252811119026. Also, does anyone have an opinion on Mobile 1 0w-40 vs. 5w-40? Can i really go 10k if I use full synthetic? My goals is to keep this car for life. Will I be able to get 300k miles out of the 550 engine? When it comes to gas, I filled up my 350 once every 2 weeks and the 550 is about the same. I also noticed it likes to lower itself sometimes after a drive...when I park and get out I notice it lowering slightly. Thanks!
