Seeing the check engine light illuminate on your dashboard can be unsettling, especially if your vehicle seems to be running normally. This warning light is part of your car’s onboard diagnostic system and is designed to alert you when something isn’t functioning as it should. While some issues are minor, others can lead to worsening engine problems if ignored. At Freeport Automotive, we provide expert check engine light diagnostics and repair in the greater Sacramento area. Here are four common check engine light triggers that should be addressed ASAP. Failing Oxygen Sensor The oxygen sensor measures the amount of unburned oxygen in the exhaust and helps regulate the air-fuel mixture. When this sensor fails, the engine may run less efficiently, leading to reduced fuel-economy and increased emissions. Ignoring a faulty oxygen sensor can cause additional strain on the catalytic converter, resulting in more expensive repairs. Malfunctioning Mass Airflow Sensor A mass airflow sensor monitors how much air enters the engine and helps determine the correct amount of fuel to inject. When it malfunctions, the engine may hesitate, idle roughly, or stall. Poor acceleration and decreased fuel-efficiency are also common symptoms. A dirty or faulty sensor is a frequent reason the check engine light turns on. Worn or Failing Spark Plugs Spark plugs are responsible for igniting the air-fuel mixture in the engine’s cylinders. Over time, they wear out, leading to misfires, and causing rough running, poor acceleration, and reduced fuel-economy. When misfires occur, the check engine light is likely to flash on, signaling the need for prompt attention. Catalytic Converter Issues The catalytic converter reduces harmful emissions by converting exhaust gases into less toxic substances. Problems with the converter often trigger the check engine light and may be accompanied by decreased engine performance or a sulfur-like smell.

Engine oil does far more than just keep parts moving—it protects your engine from damage, helps your car run efficiently, and supports long-term reliability. When oil changes are skipped or delayed, the effects can snowball into major problems that are expensive and stressful to repair. By staying on top of this routine service, you help ensure your car stays dependable. At Freeport Automotive, we provide full-service oil changes in the greater Sacramento area. Here are four reasons why following your oil change schedule matters. Proper Engine Protection Engine oil is responsible for lubricating and cooling the many fast-moving components under the hood. As oil ages, it becomes contaminated, which can reduce its ability to protect the engine. When oil can no longer do its job, friction increases, overheating becomes more likely, and major engine components begin to suffer. Regular oil changes keep your engine operating with clean, effective lubrication that prevents wear and promotes smooth performance. Improved Fuel-Efficiency A clean, well-lubricated engine runs more efficiently than one bogged down by old or dirty oil. When friction increases inside the engine, it requires more fuel to perform basic functions. This leads to reduced gas mileage and higher fuel costs over time. Fresh oil helps minimize internal resistance, allowing your engine to operate at peak efficiency. By sticking to your oil change schedule, you help maximize fuel-economy and reduce trips to the pump. Longer Engine Lifespan Engines that receive regular oil changes tend to last longer than those that are neglected. Contaminated oil can eventually turn into sludge, which can clog oil passages, restrict lubrication, and cause internal damage. Over time, this wear and tear shortens the engine’s lifespan. Routine oil changes keep harmful buildup to a minimum, helping your engine stay healthy and extending its longevity. Higher Resale Value Potential buyers often look closely at maintenance records when considering a used vehicle. A car with consistent oil change history sends a strong message that it has been well cared for. On the other hand, a spotty or incomplete service record can lower your vehicle’s value and make buyers hesitant. By following your oil change schedule and keeping documentation, you help preserve your car’s resale value and make it more attractive in a competitive market.
