Will it hurt my Subaru Ascent to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Subaru’s recommendations.

What should I do if I see leaks under my Ascent?

Don't ignore puddles of fluid under your Subaru Ascent. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are some driving habits better for my Subaru Ascent engine than others?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Enhance Subaru Ascent Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you want your 2024 Subaru Ascent’s engine to last for a long time. Regular engine tune-ups can optimize your Ascent’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Subaru, you invest in your Ascent's long-term health and engine performance.

Engine Tune-Up for Subaru Ascent

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Subaru Ascent engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your Ascent's filters, specifically replacing the air filter and fuel filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Ascent's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Ascent's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where Should I Go for My Subaru Ascent Tune-Up?

If you’re looking for 2024 Ascent engine tune-up services, head to Firestone Complete Auto Care. Follow Subaru's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
