Oil changes are one of the most essential maintenance services for any vehicle. Engine oil keeps internal components lubricated, helps manage heat, and reduces wear caused by friction. Even though oil changes are routine, many drivers still have questions about how often they’re needed and what happens if they’re delayed. At Murphy Family Auto Repair, we can answer any of your questions about oil changes in the greater Mesa, AZ area. Why Does My Car Need Regular Oil Changes? Engine oil lubricates moving parts inside the engine, allowing them to operate smoothly without excessive friction. As oil circulates, it also helps carry heat away from critical components and traps dirt and debris. Over time, oil breaks down and becomes contaminated, which reduces its ability to protect the engine. Regular oil changes help ensure fresh, clean oil is always available to keep engine parts properly protected. How Often Should Oil Be Changed? The recommended oil change interval depends on your vehicle and driving habits. Many modern vehicles can go between 5,000 and 7,500 miles between oil changes, especially when using synthetic oil—and potentially even longer. However, frequent short trips, stop-and-go traffic, extreme temperatures, and towing can require more frequent service. Checking your owner’s manual and following manufacturer guidelines is the best way to determine the right schedule for your vehicle. What Happens If I Delay an Oil Change? Putting off oil changes can lead to serious engine problems. Old oil thickens and turns into sludge, which reduces oil flow and increases friction. This can cause the engine to overheat and accelerate wear on internal parts. In severe cases, sludge buildup can block oil passages, leading to engine failure. Regular oil changes are a small investment compared to the cost of major engine repairs. What Type of Oil Is Best for My Vehicle? Vehicles require specific oil viscosities and formulations to operate correctly. Common options include conventional oil, synthetic blend, and full synthetic oil. Synthetic oils generally offer better performance in extreme temperatures and last longer than conventional oils. Using the wrong type of oil can affect engine performance and fuel-efficiency. Your owner’s manual or a trusted technician can help you choose the correct oil for your vehicle. Where Can I Get a Full-Service Oil Change in Mesa, AZ?

Few dashboard warnings create as much uncertainty as the check engine light. While it can sometimes indicate a minor issue, it may also signal a problem that affects your vehicle’s performance, fuel-efficiency, or emissions. At Murphy Family Auto Repair, we provide expert check engine light diagnostics and repair in the greater Mesa, AZ area. Here’s a look at four common reasons the check engine light comes on. Failing Oxygen Sensor The oxygen sensor monitors the amount of oxygen in the exhaust to help regulate the air-to-fuel mixture. When it fails, the engine may burn too much fuel, reducing gas mileage and increasing emissions. A faulty oxygen sensor is a common trigger for the check engine light and should be addressed promptly to prevent damage to the catalytic converter. Worn Spark Plugs or Ignition Coils Spark plugs and ignition coils are essential for proper combustion. Over time, these components can wear out or malfunction, causing engine misfires, rough idling, or hesitation during acceleration. Misfires are quickly detected by the engine computer and will often trigger the check engine light. Mass Airflow Sensor Problems The mass airflow sensor measures the amount of air entering the engine so the correct amount of fuel can be delivered. If the sensor becomes dirty or fails, the engine may experience reduced power, stalling, or poor fuel-efficiency. These performance issues commonly cause the check engine light to illuminate. Catalytic Converter Issues The catalytic converter helps reduce harmful exhaust emissions. Problems with it can lead to poor performance and unusual exhaust odors. Because of the catalytic converter’s important job, issues with it should be addressed ASAP.
