Using 5W30 instead of 5W20 oil can be problematic for your vehicle. 5W20 oil is thinner and is often specified to provide better fuel economy and proper lubrication for certain engines. Using a thicker oil like 5W30 may lead to reduced fuel efficiency and potential engine wear. Always follow the manufacturer's recommendation in your owner's manual to maintain optimal engine performance and longevity.

FAQs & Answers

  1. What happens if I mix different oil viscosities? Mixing oil viscosities can lead to reduced effectiveness in lubrication and increased engine wear. It's advisable to stick to one viscosity.
  2. What does the number in motor oil mean? The numbers in motor oil indicate its viscosity ratings. The first number (like 5W) represents cold-weather performance, while the second number (like 30) shows viscosity at high temperatures.
  3. How often should I change my motor oil? It's generally recommended to change your motor oil every 5,000 to 7,500 miles, but refer to your owner’s manual for specific guidance based on your engine.
