Maintaining your vehicle’s health is crucial for its longevity and performance. One of the most fundamental aspects of car maintenance is regular oil changes. At Roy's Auto Service in Orem, UT, we understand the importance of keeping your engine running smoothly. In this blog post, we'll explore the key signs that indicate your car needs an oil change, ensuring you stay ahead of potential issues and keep your vehicle in top condition.

Understanding the Role of Motor Oil

Motor oil plays a vital role in your car's engine by:

• Lubricating Moving Parts: Reducing friction between the engine’s components.
• Cooling the Engine: Helping to dissipate heat generated during operation.
• Cleaning: Removing contaminants and preventing sludge build-up.
• Protecting Against Wear: Minimizing wear and tear on the engine parts.

Given its critical functions, ensuring your motor oil is clean and at the appropriate level is essential for optimal engine performance.

Signs Your Car Needs an Oil Change

1. Dashboard Oil Light or Check Engine Light

The most obvious indicator is the dashboard oil light. When this light illuminates, it means your oil level is low or there's an issue with the oil system. Similarly, a check engine light can also signal that your oil needs attention. Don’t ignore these warnings—visit Roy's Auto Service in Orem, UT immediately for a professional assessment.

1. Engine Noise and Knocking

Clean oil provides a protective layer between engine parts, preventing metal-on-metal contact. If the oil is old or low, you may hear unusual noises like knocking or rumbling. This noise indicates that your engine isn't properly lubricated, which can lead to severe damage if not addressed promptly.

1. Dark, Dirty Oil

New oil is amber in color and translucent. Over time, it collects particles and becomes darker and thicker. Regularly check your oil by removing the dipstick and observing the oil's color and consistency. If it’s dark and gritty, it’s time for an oil change.

1. Oil Smell Inside the Car

If you notice the smell of oil inside your car, it could be a sign of an oil leak or that the oil is burning off due to overheating. This is a serious issue that requires immediate attention to prevent further damage.

1. Excessive Exhaust Smoke

While some exhaust vapor is normal, excessive smoke can indicate a problem with the oil. This can be due to an oil leak or the burning of oil in the engine. Either scenario necessitates a visit to Roy's Auto Service in Orem, UT to diagnose and fix the issue.

1. Decreased Fuel Economy

When your engine oil is old and dirty, your engine has to work harder, leading to decreased fuel efficiency. If you notice a drop in your miles per gallon, it might be time to change your oil.

1. High Mileage Since Last Oil Change

Consult your vehicle’s manual for the manufacturer’s recommendation on oil change intervals, typically every 3,000 to 5,000 miles. If you’ve driven more than this since your last oil change, it’s time to schedule a service at Roy's Auto Service in Orem, UT.
