Will it hurt my Jaguar XJ8 to drive with old spark plugs?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What does a puddle underneath my Jaguar XJ8 mean?

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 XJ8 engine?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Tune-Ups to Help Your Jaguar XJ8 Run Better

Is your engine overdue for a tune-up? 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 1999 Jaguar XJ8’s engine to last for a long time. Routine engine tune-ups can bring power back to your XJ8. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by Jaguar, you invest in your XJ8's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Jaguar XJ8

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1999 Jaguar XJ8. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your XJ8. 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 XJ8's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your XJ8 can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! 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 Jaguar XJ8 Tune-Up?

If you’re looking for 1999 XJ8 engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Jaguar, 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, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
