Q: I've got an older car, how important is it to change oil as frequently? An oil change puts fresh oil into your car. More importantly, an oil change takes out the old oil that can become filled with dust, metallic shavings or other contaminants. As your oil ages, outside items make their way in. Without an oil change, this can lower your gas mileage or in the worse case, cause your engine to fail. An oil change is a great preventive step to keep you car running clean and smooth. Make sure to change your oil filter as well, it helps to remove impurities from the oil and the engine.
Q: I've heard different things about how often to change my oil. What's the best guide? A good rule of thumb is every 3,000 miles for an oil change. However, follow your vehicle manufacturer's recommendations. They will specify the frequency for an oil change for your driving conditions. The timing of your oil change should follow those recommendations.
