Thicker oil can reduce oil consumption in some engines, especially older ones with worn seals and piston rings. However, it is essential to use the oil viscosity recommended by your vehicle's manufacturer to avoid potential engine damage or performance issues.

FAQs & Answers

  1. Can using thicker oil damage my engine? Using oil that is thicker than the manufacturer’s recommended viscosity can cause engine performance issues and potential damage, so it’s important to follow the vehicle’s specifications.
  2. Why does thicker oil reduce oil consumption in some engines? Thicker oil can reduce oil consumption by providing a better seal in worn engines with old piston rings or seals, slowing the rate at which oil is burned off.
  3. Should I switch to thicker oil if my car consumes oil? Before switching, consult your vehicle’s manual or a mechanic; thicker oil might help in older engines but could negatively affect newer engines designed for specific viscosities.
