Frequently Asked Questions (FAQ)

Q: How often should I change my car’s engine oil?

A: Consult your car’s owner’s manual for the recommended oil change interval. This typically ranges from 3,000 to 10,000 miles, depending on the type of oil used and driving conditions.

Q: What does the SAE number (e.g., 10W-30) mean?

A: The SAE number indicates the oil’s viscosity (thickness). The “W” stands for winter. The lower number before the “W” indicates the oil’s fluidity at low temperatures, while the higher number after the “W” represents its viscosity at high temperatures. 10W-30 is a common grade suitable for a wide range of temperatures.

Q: What’s the difference between conventional, synthetic blend, and full synthetic oil?

A: Conventional oil is refined from crude oil. Synthetic blend oil mixes conventional and synthetic oils. Full synthetic oil is entirely manufactured, offering superior performance and protection.

Q: Can I use any engine oil in my car?

A: No. Always refer to your owner’s manual for the recommended oil type and viscosity grade. Using the incorrect oil can damage your engine.

Q: What are the signs that I need an oil change?

A: Signs include a low oil level on the dipstick, a dirty or dark-colored oil, unusual engine noise, reduced fuel efficiency, or warning lights on the dashboard.

Q: Is synthetic oil always better than conventional oil?

A: Synthetic oil generally provides better performance and protection, especially in extreme conditions. However, it’s more expensive. The best choice depends on your vehicle, driving habits, and budget. Always consult your owner’s manual.

Q: What is the best way to dispose of used engine oil?

A: Do not pour used oil down the drain or into the trash. Take it to a local recycling center or auto parts store that accepts used oil for proper disposal. This protects the environment.
