Deciphering the Code 5w30 vs. 5w40 Explained for Optimal Engine Health

I believe 5W-40 would actually be better! It might increase fuel consumption slightly, but I don't see any other issues with using it. The 5 is the same. The 40 is higher viscosity at operating temps, compared to 30. The engine was designed for 5w30. compared to the 0W20 oil. So the 5W30 oil perform the best, but the 5W20 oil perform just about as well. It's very common for people to refer to ... Either is fine. The important bit is the LL01 or LL04. LL04 is mandatory for diesels with DPF filters, LL01 is fine for everything else ... 0w40 vs 5w40. Learn the key differences between 0W40 and 5W40 engine oil. Find out which oil viscosity grade is better for cold weather ... Based on the viscosity grade, you can notice that 5w30 oil will be more liquid while the 5w40 is more viscous and thicker so that is why 5w30 ... Not sure which motor oil or gear oil your vehicle requires? You're not alone! Because approvals, specifications and viscosities such as 0W-30, 5W-30, ... We work side-by-side with workshops to produce high quality engine oils, lubricants and chemicals for passenger cars and commercial vehicles. 5W40 is thicker at higher temperatures and remains more stable than 5W30 in hot weather conditions. While both oil types resist breakdown in ... 5W-40 is as thick as single grade 40 weight at 100°C, and will pump down to -30°C (at least right after oil change).
