Yes, it is usually okay to mix oil brands as long as the oils are of the same viscosity and meet the required specifications (like API or ACEA ratings). However, for optimal performance, it's best to stick to the same brand and type of oil.

FAQs & Answers

  1. What happens if I mix different oil brands? Mixing different oil brands is generally safe if they have the same viscosity and specifications; however, it's best for optimal performance to use the same brand.
  2. How do I know if oil brands are compatible? Compatibility can be determined by checking if the oils have the same viscosity (SAE rating) and meet the same performance specifications, like those provided by API or ACEA.
  3. Is it safe to use synthetic and conventional oils together? You can mix synthetic and conventional oils, but it may reduce some benefits of the synthetic oil. It's recommended to use oils that are compatible for best results.
  4. What are API and ACEA ratings? API (American Petroleum Institute) and ACEA (Association des Constructeurs Européens d'Automobiles) ratings provide guidelines on the performance and quality of engine oils.
