Selecting Oil for Tractor

The kind of oil your tractor should use depends on several factors. If you need help determining which tractor engine oil to use, check the owner’s manual to learn about all the specifications.

Viscosity: Check the viscosity grades that the original equipment manufacturer (OEM) recommends. The appropriate oil viscosity for your tractor engine depends on the expected ambient (outside air) temperatures. You can use the SAE number on the oil bottles to determine the oil that can flow at ambient temperatures.

Engine oil capacity: The oil capacity of your tractor’s engine is the quantity of oil the engine can accommodate. Typically, the amount of oil your tractor can accommodate depends on its oil pan. You can use the operation manual to understand the actual oil capacity based on the oil pan.

How To Check Tractor Engine Oil

Checking your tractor’s oil level and quality is part of your maintenance project you’ll need to do regularly. Typically, the frequency of use determines how often you should check the tractor oil.

  • Slowly add the engine oil to the oil fill hole to avoid spilling it on the engine.
  • Allow the oil to settle for about three minutes before checking its level.
  • If the oil is below the normal range, add some more. Loosen the drain plug to remove excess oil if it’s above the normal range. Recheck with the dipstick to ensure the oil is at its normal range.
  • Replace the oil cap. Ensure to hand-tighten the oil cap to avoid damaging it.

Changing Tractor Engine Oil

When checking the oil level, you can use this chance to determine whether you should change it. Generally, you’ll need to change the oil for the tractor once every six months. Always confirm the recommended time from the owner’s manual.

  3. Remove the oil filter: To remove the oil filter, you need an oil filter wrench to loosen it. Once it’s loose, remove it slowly.
  4. Install the new oil filter: Use the specification on the filter or the owner’s manual to install the oil filter. You can apply a thin layer of oil around the filter to allow it to spin smoothly.
