Why Premium Fuel Matters For Your BMW’s Fuel Injectors In Bellingham

Posted on June 7, 2025 by Carson Wileman

To keep your BMW running at its best, you need to make sure you are taking care of all parts of your vehicle including the fuel injectors. An easy way to maintain the performance and longevity of your vehicle’s fuel injectors is by using premium fuel. While it may seem like a small detail, the type of fuel you use can affect the way your BMW performs.

What Are Fuel Injectors and Why Are They Important?

Fuel injectors are responsible for delivering the right amount of fuel into the combustion chamber at the right time. Think of the fuel injectors like a garden hose nozzle. You can’t water your garden too heavily or too little, it has to be just right. The injectors spray fuel into the engine as a fine mist, which helps create a proper air-fuel mixture, allowing the engine to run smoothly and efficiently. If the fuel injectors become clogged, damaged, or malfunction, you can find that your BMW will have you spending more time at the gas station and running rough.

Premium Fuel vs. Regular Fuel

Premium fuel, typically rated at 91 octane or higher, contains higher-quality additives than regular fuel. These additives help to clean the engine, improve combustion efficiency, and reduce harmful emissions. While regular fuel (typically 87 octane) may be sufficient for many vehicles, BMW engines are designed to operate most efficiently with premium fuel. The higher octane content in premium fuel prevents knocking or pinging during combustion.

When you use premium fuel, you’ll be giving your engine the things it needs to operate at its best! As a BMW owner, you most likely chose the BMW because of its reputation as a high-performing vehicle. You want to make sure you do all the right things and that means using the right fuel.

How Premium Fuel Benefits Your BMW’s Fuel Injectors

Premium fuel contains detergents and additives that help clean the fuel system, including the fuel injectors. These cleaning agents help remove carbon deposits and other dirt and debris that can build up over time. If your fuel injectors are exposed to cleaner fuel, they will operate better and are less likely to become clogged and cause bigger problems.

Engine knocking occurs when the air-fuel mixture in the engine’s cylinders detonates unevenly, which can lead to significant damage over time. Premium fuel is made to reduce the chances that your engine will start knocking. Less knocking means less stress on the fuel injectors and that can keep your engine running smoother longer.

When your fuel injectors are working properly and the combustion process is more efficient, you’ll notice that you spend far less time at the gas pump and more time behind the wheel. Premium fuel helps to make sure that the injectors are delivering the right amount of fuel at the right time, saving you money over time because there is much less waste!

By using premium fuel, you are essentially taking better care of your fuel injectors. Cleaner fuel reduces the amount of carbon and gunk that builds up inside the injectors, which can lead to clogging and poor fuel spray patterns.
