The real trick to getting more MPG in the city is coasting. By letting off the gas 5-10 seconds before you'd normally do and let the car coast to an upcoming stop sign & redlight your mpgs shoot up and you save gas in the process. Another great trick is timing the green lights and speeding up & slowing down as necessary as to avoid redlights all together, you can squeeze out a few MPGs this way as well.
The biggest boosts to MPG though are crank pulley & Royal Purple fluids, those two can have drastic positive results. |
I could post my W211 CDI figures too but I don't think those have a lot of relevance when comparing to a W221. I don't disagree with your advice to save fuel but then again, the example was from highway driving where traffic lights are less of an issue.
Your comment about engine oil was interesting, I was wondering why I feel like getting 0.2 to 0.3 l/100km better figures than those I feel I used to get at similar trips and started wondering if the engine oil from the factory had some break-in additives that affect fuel consumption?
