Q:
A: for your merc to perform with maximum efficiency, check oil pressure and see if it needs a changing. In a mercedes dealership, ask for your engine to be checked and any electrical systems within, as some of the electrics in the early 2000's merc's have proven to be faulty through long ownership, especially the 02 ml320. I would check for that and crucially and just as importantly, check suspension and damping to make sure its in strong responsive order and pump your tires fully. This should ensure much better on-road responsiveness and much more precise steering. This is a true and proven fact, and even has a positive effect on economy, improving mpg. How it does this is that the pumped tyres improve overall wheel traction and grip on road and makes it easier for the engine to respond to with precise wheel aligning. hope this info helps niall a.
