What happens if my Oldsmobile Cutlass Supreme spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my Cutlass Supreme?

Don't ignore puddles of fluid under your Oldsmobile Cutlass Supreme. 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.

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.
