Will it hurt my Infiniti QX56 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What should I do if I see leaks under my QX56?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my QX56 engine?

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.

Tune-Ups to Help Your Infiniti QX56 Run Better

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you drive a 2012 Infiniti QX56. Routine engine tune-ups can bring power back to your QX56. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Infiniti, you can rest assured you’re investing in your QX56’s long-term engine performance.

Routine Engine Tune-Up Service for Your Infiniti QX56

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2012 Infiniti QX56. One option 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*. Another service option pays special attention to the filters in your QX56. Specifically, we replace the fuel filter and air filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your QX56. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your QX56 can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. 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 Infiniti QX56 Tune-Up?

Schedule your next 2012 QX56 engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Infiniti, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, engine knocking, or an illuminated check engine light.
