Understanding Tractor Engine Oil

We want to teach you all about engine oil to help your tractor run better and last longer.

If you do not feel that you understand these tips, steps, and strategies, or can perform them safely, consult your tractor dealer or local mechanic.

NOTE: There are a few important things to know before servicing your oil.

Here are a few:

  • Only use the engine oil specified. Other engine oils may affect warranty coverage, cause internal engine components to seize, and/or shorten engine life.

  • Never overfill the oil. Overfilling may result in white exhaust smoke,engine overspeed, or internal damage.

  • Prevent dirt and debris from contaminating the engine oil. Carefully clean the oil cap/dipstick and the surrounding area before you remove the cap.

  • Never mix different types of engine oil. This may adversely affect the lubricating properties of the engine oil.

  • Engine Oil Specifications

  • Use an engine oil that meets or exceeds the following guidelines and classifications.

Service categories:

  • API service categories CD, CF, CF-4 and Cl-4

  • ACEA service categories E-3, E-4, and E-5
