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 higher temperatures. 5W-30 is a common grade suitable for a wide range of vehicles and climates.

Q: How often should I change my oil?
A: Consult your owner’s manual for the recommended oil change intervals. This will vary depending on your vehicle, driving habits, and the type of oil used. High-mileage oils often allow for longer intervals, but it’s crucial to adhere to the manufacturer’s guidelines.

Q: What are the signs of needing an oil change?
A: Signs include a low oil level (check your dipstick), dark or dirty oil, unusual engine noise, reduced engine performance, or a check engine light.

Q: Can I mix different brands of 5W-30 oil?
A: While it’s generally not recommended to mix different types of oil (synthetic vs. conventional), mixing the same viscosity grade (5W-30) from different reputable brands is usually acceptable in a pinch. It’s best to avoid this if possible and stick to a single brand and type for consistency.

Q: What is the difference between synthetic, synthetic blend, and conventional oil?
A: Synthetic oils are engineered for superior performance and longevity. Synthetic blends combine synthetic and conventional oils, offering a balance of performance and cost. Conventional oils are refined from crude oil and offer less protection and shorter drain intervals.

Q: My car is burning oil. Should I switch to a high-mileage oil?
A: High-mileage oils often contain seal conditioners that can help reduce oil leaks and consumption. Switching to a high-mileage oil might help, but significant oil burning could indicate a more serious engine problem requiring professional attention.
