Does this car run on 92 or 95 fuel?

Anything above 92 is fine.

92 is sufficient.

I'm using 95 octane fuel [lightbulb moment].

It's best to choose 95 for a turbocharged engine.

This car is best fueled with 95. Mercedes requires 95. If there's an emission warning, some cars have it disappear after driving a tank of 95. You can give it a try.

Using 92-octane gasoline is perfectly fine for regular use. However, if you're more focused on fuel economy or power, 95-octane would be a better choice.

According to the manufacturer, this car only requires 92 octane gasoline. Normally, using 92 is perfectly fine, but you can also use 95 if you want.
