What kind of gas does a 2002 Mercedes E320 use

PREMIUM. I have a 2012 E350 4MATIC AMG that I hand ordered, and bought brand new. It the manual it clearly states "PREMIUM UNLEADED GASOLINE IS RECOMMENDED". Your engine, fuel economy, and pocketbook will thank you down the road. Cheap gas is just that, cheap and it causes carbo build up, injector corrosion, and poor gas mileage as it is crude and harder for the engine to burn.

Hey thanks just got it had A couple of bmws so been using premium I was wondering if it too diesel good looking.

I have a 2002 E-320 Mercedes-Benz, I can't get in my truck. Is there a way to get into it without using the clicker are the key. I just purchased a new key. It was good fine, the one day is couldn't use the key are the clicker. Please some help me.

I have ask a question and haven't gotten a response

Silliness! The only issue, and it is a big one, is that lower octane fuel will pre-ignite, especially in hot weather. MB engines have higher compression ratios in order to increase performance, and that causes pre-ignition ("pinging,") especially in hot weather. The computer should rein the engine back, but that will undermine performance.
