Should you replace single-grade engine oils more often than multi-grade oils?

One object of your engine oil is to keep your pistons and other internal moving parts healthy and well-lubricated. The various grades of motor oil, including single and multi-grades, both do this job well so long as their viscosity levels hold steady.

Viscosity is the way your oil reacts to variations in temperature and pressure found inside your motor. For the best results, your oil viscosity should match the demands of your unique engine.

While single and multi-grade oils maintain viscosity under tough conditions, some single-grade varieties include additives that can, over time, build-up inside the motor. These build-ups can cause eventual performance issues, and may even cause more significant issues if left to their own devices. Because of this tendency, single-grade oils sometimes require more frequent replacement than multi-grade varieties. Examples of single and multi-grade viscosity codes include:

  • Single Grade: 10, 20, 30, 40, 50, 60
  • Multi-Grade: 0W-15, 5W-20, 10-W25
