Will it hurt my Oldsmobile Custom Cruiser 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 Oldsmobile’s recommendations.

What should I do if I see leaks under my Custom Cruiser?

Don't ignore puddles of fluid under your Oldsmobile Custom Cruiser. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are some driving habits better for my Oldsmobile Custom Cruiser 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.
