Additives in gasoline
One of the main problems of poor fuel quality is the forming of deposits that are created during the gasoline combustion process.
Mercedes-Benz recommends that you use fuel brands that have the additives.
Deposits may form if you use fuels without additives over a longer period of time. These deposits are most likely to form 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. Comply with 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.
