2020 Model Research

No matter your model, BMW recommends using only premium-unleaded fuel.

That’s not to say your BMW won’t run on lower-grade fuel, but premium-unleaded fuel will maintain its quality in the long run, letting you drive at peak performance consistently.

Allow the BMW experts at our dealer serving Hackensack explain further.

What’s The Difference Between Regular and Premium Fuel?

Octane levels. Regular fuel has an octane rating around 87, whereas premium fuel, as its name may suggest, boasts a higher rating of 91 plus. 

What Are Octane Levels?

Octane levels indicate the stability of fuel under pressure. More octane translates to better stability. In a real-world sense, think of premium fuel as a healthy, well-balanced meal and regular fuel as fast food.

What Are The Risks Of Using Low-Octane Fuel In My BMW?

A quick lesson about an engine cycle: an air-fuel mixture is forced into the combustion chamber, the spark plug ignites it, and the subsequent explosion emits power. When an engine with a higher compression ratio, like those equipped in the models among our new BMW inventory, uses less stable fuel, it can prematurely combust – a phenomenon called “knocking” or “pinging” because of the rattling noise it makes.

Think about getting ready to run a 100m dash. Right before taking that imperative first step, your leg is already mid-stride. You lost the potential necessary for an optimal lift-off.

Knocking can hurt performance and cause damage to your engine. However, many modern engines make use of technology to minimize damage from using low-octane fuel. It’s up to you whether you want to run that risk.

How Does Premium Fuel Affect My BMW Vehicle’s Performance?

It doesn’t. Rather, it ensures the consistent operation of your engine because high-octane fuel resists knocking. BMW vehicles are known for their high performance, so they need better quality fuel to run from the get-go. Don’t think of it as “premium” fuel, think of it as the base fuel for a premium vehicle.
