Checking your dipstick is a simple way to monitor oil condition. Fresh oil is amber-colored and smooth, while old oil often looks darker, thicker, and may contain particles. Additionally, your vehicle’s mileage plays a key role. While older advice suggested oil changes every 3,000 miles, Edmunds notes that modern vehicles with synthetic oils can often go 7,500 to 10,000 miles between changes, depending on your driving conditions and manufacturer recommendations.*

You may need more frequent oil changes if you often drive in stop-and-go traffic or make frequent short trips.

One of the clearest indicators you need an oil change is the appearance of the oil change or check engine light. These warnings are built into your car’s system to alert you when oil pressure is low or when the oil quality has deteriorated. Ignoring these lights can lead to more serious problems, including engine damage. If a warning light comes on, schedule a service appointment right away with our technicians.

Clean oil cushions and protects the moving components inside your engine, allowing them to operate smoothly without creating excessive friction. When the oil becomes dirty, too thin, or begins to break down, it can no longer provide the same level of protection. As a result, you may start to notice unusual sounds such as knocking, grinding, or ticking, especially when starting the vehicle after it has been sitting. These noises are often a sign that metal parts are making direct contact without adequate lubrication.

If you see blue or dark smoke coming from your exhaust, it can signal that oil is burning in the engine. Likewise, a strong smell of oil inside the cabin may indicate a leak. Both issues should be addressed immediately to prevent more complex repairs. Regular oil changes prevent these symptoms and allow our technicians to spot small leaks before they become larger problems.

Why Oil Changes Matter

An oil change restores the proper level of lubrication and helps the engine return to smoother, more responsive performance. Fresh oil also carries away heat more effectively, reduces harmful deposits, and allows the engine to operate as designed. By addressing these signs early, you’re not just eliminating unpleasant sounds and sluggish response—you’re extending the life of your vehicle and preserving its reliability for daily driving and longer trips.
