The Mercedes C class is the entry line sedan for Mercedes. Therefore, they are widely available. You can find new ones at your nearest Mercedes dealer but should also be able to find numerous used ones at used car lots, at mega lots like Carmax and from private sellers.
I used top octane in my 1998 E320 before gas prices got up to $4.00 - now I use the middle octane. Mercedes recommends Premium fuel because of the way the engine is designed and the sensors. It runs much better on premium anyways. and if you cant afford the premium gas you have no business owning a mercedes.
It calls for 91 octane fuel. However the engine does have a know sensor so it will adjust ignition timing to keep from damaging the engine if a lower octane fuel is used.
Premiun unleaded 92 octane or higher. Using a lower octane fuel will cause valve chatter and loss of some power as well as potential engine damage.

No, octane is not a base. Octane is a hydrocarbon compound, specifically an alkane. It is commonly found in gasoline and used as a fuel.
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115
the higher the octane the better it burns and you get less build-up in your pistons, some vehicles recommend higher octane ! these are most likely used in the faster cars for drag racing to get up more speed and when it reacts, it glows a bright white
regular unleaded 87 octane
Iso-octane is commonly used as a reference standard to measure the octane rating of gasoline. It is also used as a blending component in gasoline to improve its octane rating and reduce engine knock. Additionally, iso-octane is used in the production of solvents, adhesives, and paints.
