Will it hurt my Lexus SC400 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 Lexus’s recommendations.

What should I do if I see leaks under my SC400?

Are hard starts and stops bad for my Lexus SC400 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.

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 1998 Lexus SC400. Regular engine tune-ups can optimize your SC400’s power on the road. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions.

Lexus SC400 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1998 Lexus SC400. 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*. Another service option pays special attention to the filters in your SC400. Specifically, we replace the fuel filter and air 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 SC400's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your SC400'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.
