When should Jaguar XJ spark plugs be replaced?

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 do I do if I see a pool of liquid under my Jaguar XJ?

Are some driving habits better for my Jaguar XJ engine than others?

Tune-Ups to Help Your Jaguar XJ Run Better

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 2015 Jaguar XJ in tip-top shape. Routine engine tune-ups can bring power back to your XJ. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Jaguar's recommendations, you’re taking vital steps toward keeping your XJ’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Jaguar XJ

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2015 Jaguar XJ. The standard Firestone Tune-Up is one service option. 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 XJ'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 XJ's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your XJ's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
