When should Oldsmobile Cutlass Supreme spark plugs be replaced?

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 Oldsmobile’s recommendations.

What does a puddle underneath my Oldsmobile Cutlass Supreme mean?

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.

What do hard starts and stops do to my Cutlass Supreme 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 Oldsmobile Cutlass Supreme

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, particularly if you want to keep your 1991 Oldsmobile Cutlass Supreme in tip-top shape. Routine engine tune-ups can bring power back to your Cutlass Supreme. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy.

Engine Tune-Up for Oldsmobile Cutlass Supreme

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Oldsmobile Cutlass Supreme engine tune-up services. One option 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*. The second service focuses on your Cutlass Supreme'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 Cutlass Supreme'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 Cutlass Supreme can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
