Additives in gasoline

One of the main problems of poor fuel quality is the forming of deposits that are caused during the gasoline combustion process.

Mercedes-Benz recommends that you use fuel brands that have the additives.

If you use fuels without these additives for an extended period of time, there may be a buildup of carbon deposits, especially on the inlet valves and in the combustion chamber.

This could lead to engine problems, e.g.:

 - longer engine warm-up phase
 - uneven idle
 - engine noise
 - misfiring
 - loss of power

Carbon deposits may form if the availability of gasoline with relevant additives is insufficient (in certain regions). In this case, Mercedes-Benz recommends the use of additives that have been approved for Mercedes-Benz vehicles.

Consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only) for a list of approved products. Observe the instructions for use on the product label.

Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine.

Do not refuel with low-grade fuel and do not use fuel additives that are not tested and approved for Mercedes-Benz vehicles.

Damage to or malfunctions of the fuel system may otherwise occur.
