November 15th, 2025

Your Nissan's engine depends on precision-especially when it comes to delivering fuel. Over time, carbon deposits and impurities can clog your fuel injectors, causing reduced efficiency, sluggish acceleration, and poor fuel economy. That's where a fuel injector cleaning service comes in. At Capitol Nissan in Salem, OR, our factory-trained technicians use specialized equipment and Nissan-approved solutions to clear away buildup from each injector. This service restores your engine's ability to deliver the perfect air-to-fuel ratio-resulting in smoother performance, better fuel mileage, and reduced emissions. Whether you drive a commuter-friendly Sentra or a rugged Frontier, clean injectors help your vehicle run like new again. By removing harmful residue, this service helps prevent misfires, improves throttle response, and protects the long-term health of your engine. It's a simple yet powerful way to keep your Nissan performing its best.

Why Fuel Injector Cleaning Is Essential for Your Nissan

Fuel injectors are responsible for delivering precise bursts of fuel into your engine's combustion chambers. When dirt or carbon buildup interferes with this process, your vehicle must work harder to compensate-leading to higher fuel consumption and uneven performance. Ignoring dirty fuel injectors can lead to rough idling, slow starts, stalling, or even engine knocking. Over time, that strain can cause more expensive problems, such as damaged spark plugs or catalytic converter issues. A professional fuel injector cleaning not only improves power and efficiency but also helps prevent these costly repairs. At Capitol Nissan, we use professional-grade cleaning tools and detergents that go far beyond store-bought additives. Our process clears each injector internally, restoring a consistent spray pattern and ensuring your Nissan's engine runs with precision once again.

How Often Should You Schedule Fuel Injector Cleaning?

The right interval for a fuel injector cleaning service depends on how-and where-you drive. For most Nissan models, we recommend scheduling this service approximately every 25,000 to 30,000 miles. However, if you frequently drive in city traffic, make short trips, or use lower-grade fuel, you may benefit from cleaning more often. Common signs that your injectors need attention include reduced gas mileage, rough idling, hesitation during acceleration, or the check-engine light turning on. If you've noticed any of these symptoms, it's a good time to book an inspection. Our service team will test your system and advise whether cleaning or other fuel-system maintenance is necessary. By staying ahead of injector buildup, you'll keep your Nissan running smoothly and efficiently-mile after mile through Salem and beyond.
