Premium gives better gas mileage Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.

Is premium gas really worth it?

What happens if you put regular gas in a Benz?

Regular gas can reduce the life of the engine, trigher malfuctions such as Check Engine Light and most importantly it can cause the fuel to pre-ignite, causing pre-detonation (engine knocking). Using lower rated gasoline on your Mercedes-Benz not only causes problems but also decrease the fuel efficiency.

What happens if you mix 89 and 93 gas?

No, you will not damage your engine by mixing different octane fuel. It is still fuel. Say you mixed 2 gallons of 87 octane with 2 gallons of 89 octane and 2 gallons of 93 octane. … If you ran octane too low, the engine will knock (not terribly bad for it, but again a loss in power).

87 is the standard octane rating that most car engines are designed for. … The reason why you should never run a lower octane fuel on a vehicle tuned for higher octane fuel is because the tune has no way of detecting what fuel you are using and will continue to operate assuming you put in the correct fuel.

Does premium gas last longer?

Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.

Can premium fuel damage engine?

The higher the octane, the greater its ability to prevent the unruly type of combustion engineers call detonation. The goal is to ignite the fuel mixture solely with the spark plug, rather than from the heat in the cylinder, to prevent detonation, which can seriously damage high-performance engines.
