Is 75W140 Thicker than 75W90? Understanding Viscosity Differences

Discover the viscosity differences between 75W90 and 75W140 oils and find out which is thicker for better performance.

24 views

75W140 is thicker than 75W90. The numbers refer to the viscosity grades of the oil at different temperatures. Higher numbers indicate thicker oil, so 75W140 provides more thickness and higher protection under extreme conditions compared to 75W90.

FAQs & Answers

  1. What does the 'W' in oil viscosity mean? The 'W' stands for 'winter' and indicates the oil's viscosity rating in cold temperatures.
  2. How do you choose the right motor oil viscosity? Consider your vehicle specifications, climate, and driving conditions to select the appropriate viscosity grade.
  3. Can I mix different viscosity oils? While it's generally not recommended, mixing different oils may not cause immediate damage but can affect performance.
  4. What are the benefits of using thicker oil? Thicker oil can provide better protection and lubricant in high-temperature conditions but may affect fuel efficiency.
