Will it hurt my BMW 740i 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 BMW’s recommendations.

What does a puddle underneath my BMW 740i 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.

Are hard starts and stops bad for my BMW 740i engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Tune Into Your BMW 740i

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 1998 BMW 740i’s engine to last for a long time. Periodic tune-ups can bring more power back to your 740i’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on BMW's recommendations, you can rest assured you’re investing in your 740i’s long-term engine performance.

Routine Engine Tune-Up Service for Your BMW 740i

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1998 BMW 740i. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your 740i's filters, specifically replacing the air filter and fuel 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 740i. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your 740i: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where Should I Go for My BMW 740i Tune-Up?

If you’re looking for 1998 740i engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from BMW, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
