How to Change the Oil in a Murray Lawn Mower

Murray uses either a Briggs and Stratton engine or a Tecumseh engine to power its lawn mowers. The company suggests changing the oil every 25 hours of use or at the beginning of each season, whichever comes first. Changing the oil in a Murray lawn mower is the same as with any other mower. Murray suggests using SAE 30 motor oil for both riding and push mowers. Call an auto parts store to find disposal locations for the used mower oil.

Murray Riding Mower

Park the Murray lawn tractor on level ground. Allow the mower to run for two minutes to warm up the oil. Warm oil drains more freely than cold oil. Shut off the engine and pull the key out of the ignition.

  • Murray uses either a Briggs and Stratton engine or a Tecumseh engine to power its lawn mowers.
  • Allow the mower to run for two minutes to warm up the oil.

Open the hood of the mower and locate the oil fill tube. The fill tube has a yellow cap, and the dipstick attaches to the bottom of the cap. Turn the cap counterclockwise with your hands, and remove the cap from the fill tube. Wipe the dipstick with a shop rag and place the cap/dipstick to the side.

Find the oil drain tube on the right side of the engine between the driver's seat and front wheel. The drain tube protrudes from the side and has a yellow cap on the end. Pull the cap off the drain tube with your fingers. Place a drain hose over the end of the drain tube. The Murray riding mower comes with a 1/2-inch diameter drain hose that is 1 foot long. If you cannot find the original drain hose, purchase a piece of 1/2-inch diameter plastic or rubber hose.

  • Open the hood of the mower and locate the oil fill tube.
  • Wipe the dipstick with a shop rag and place the cap/dipstick to the side.

Place a container to catch the oil beneath the open end of the drain hose. Push the drain tube inward and turn the tube counterclockwise to drain the oil from the engine. When no more oil drains, push the drain tube inward and turn the tube clockwise until the locking pin engages. Pull the hose off the drain tube, and wipe the end of the tube with a rag. Push the yellow cap back over the end of the tube.

Pour 48 ounces of SAE 30 motor oil into the fill tube slowly. Push the dipstick into the fill tube, and pull the dipstick back out to check the oil level. Add oil as necessary until the dipstick reads full. Place the cap/dipstick into the fill tube and turn clockwise to lock the cap. Close the mower hood.

  • Place a container to catch the oil beneath the open end of the drain hose.
  • Push the dipstick into the fill tube, and pull the dipstick back out to check the oil level.

Murray Push Mower

Place the Murray push mower on level ground. Start the engine and allow it to run for two minutes to warm the oil. Shut the engine off, and pull the spark plug wire off the spark plug. Snap the wire into a hook located on the front of the engine while the wire is disconnected from the spark plug.

Place a container on the same side of the mower as the oil fill tube. Turn the oil fill tube cap counterclockwise with your fingers to remove the cap. The dipstick attaches to the bottom of the cap. Wipe the dipstick with a rag and set it to the side.

  • Place the Murray push mower on level ground.
  • Snap the wire into a hook located on the front of the engine while the wire is disconnected from the spark plug.

Tilt the mower on its side to allow the oil to drain from the fill tube into the container. Place the mower back on all four wheels when no more oil drains from the fill tube.

Pour 48 ounces of SAE 30 motor oil into the fill tube slowly, and check the oil level with the dipstick. Place the dipstick and cap back into the fill tube. Turn the cap clockwise to lock it in place. Push the spark plug wire onto the spark plug.
