FAQ:

Q: What does 5W-30 mean?
A: 5W-30 refers to the oil’s viscosity grade. The “5W” indicates its performance in cold temperatures (the lower the number, the better the cold-weather performance), and the “30” indicates its performance at high temperatures.

Q: How often should I change my oil?
A: Consult your owner’s manual for the recommended oil change interval. It will typically vary depending on the type of oil used and your driving habits.

Q: Is synthetic oil worth the extra cost?
A: Generally, yes. Synthetic oils offer superior protection, longer life, and better performance compared to conventional oils, particularly in turbocharged engines.

Q: Can I mix different types of oil?
A: It’s generally not recommended to mix different types of oil (e.g., synthetic with conventional). If you must, use a similar viscosity grade.

Q: What are the signs of needing an oil change?
A: Signs include low oil pressure, engine knocking, unusual noises, or dark, dirty oil.

Q: What’s the difference between a synthetic blend and full synthetic?
A: Full synthetic oils are made entirely from synthetic base stocks, offering superior performance and protection. Synthetic blends contain a mixture of synthetic and conventional base stocks.

Q: Does using a higher-quality oil improve fuel economy?
A: Some higher-quality oils, with advanced friction modifiers, can potentially improve fuel economy, but the effect may be small and dependent on other factors.
