Guys its this issue troubling me for some time so i decided to bring it up. Here's the thing: Whenever I full my fuel tank, I realize that before filling it my acceleration was not as fast it was with a full fuel tank! Does the ECU handles differently the amount injected considering the level of the fuel tank ?

Not in any car I've ever driven, including the C230. Fuel flow should be consistent until the tank is empty, then you'd have major power loss!

hmmm I've read somewhere that when the fuel tank is nearly empty there's an increasment of the fuel temperature and that causes power loss

These cars arent fast to begin with but I have 120k on my engine and Im noticing power loss. Its even hesitating a bit now.

Doesn't happen in my 2005 - power is the same, full or with 0 miles displaying on the range. Also have 122,600 miles and it runs the same as it did with 25,000. You shouldn't be having issues.

Ill go with LiLBEnz on this one. No power loss - thats what benz is all about!

Your prob exp a placebo effect, subconsciously your prob going much lighter on the car because you know you need gas, and once full don't mind going WOT

Fuel system is cooled by the fuel, if you run low on fuel things will run hotter. (fuel pump,injectors)

RobertG U ARE THE MAN! yeah thats a pretty rational explanation
