Will it hurt my BMW 740iL 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 740iL?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my BMW 740iL engine than others?

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.

How often should I clean my BMW 740iL fuel injectors?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune-Ups to Help Your BMW 740iL Run Better

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, particularly if you want to keep your 1998 BMW 740iL in tip-top shape. Periodic tune-ups can bring more power back to your 740iL’s engine. 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 follow the guidelines specified by BMW for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your 740iL’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your BMW 740iL

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1998 BMW 740iL. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your 740iL. 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 740iL. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your 740iL can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
