WHICH GAS GRADE TO USE FOR c300?? - Page 2 - Benzworld.org

Mixing different grades of fuel is no problem at all. Hell, some stations blend low octane and high octane right at the pump to get mid-grade. About the only drawback of you doing it is the hassle of starting and stopping the pump to complete a sale for each type of fuel. A plus is that you can change the ratio of premium to regular to get something above the normal mid-grade.

Running a higher octane fuel than your engine requires is not a problem. It's just a waste of money. Kind of like giving a bottle of fine wine to a wino. It "works" but the quality of the product is totally lost on the consumer. ;-)

Minimum of 91 octane, if I recall correctly.

Premium, per what's printed on gas cap cover.

The requirement for all MB's are minimum 90 octane. They only sell 87,89,91,93 where I am so I use 91.

It depends. How much 93 was left? In order for the car to calibrate the ignition to the fuel used, it is generally recommended that the tank be as close to empty as possible. Anywhere between empty and an eigth of a tank is ideal.
