I don't quite understand your question, but at about 7.6km per liter, you would need approximately 13 liters to drive 100km.</P>


If you're asking about how to save gas, or get better fuel ecomomy, the best thing I could tell you is to use premium 92 octane gasoline. Mercedes engines are designed to use 92 octane, and if you use 87 octane, your car will probably develop a pinging sound. It won't hurt to use 87 octane, but 92 octane is much more efficient, and actually burns slower, saving you gas.</P>

 

Many thanks for your words.</P>


It's helpful.</P>
