How to Change Oil in Sears' Lawn Mowers

Sears sells a wide variety of lawn mowers with varying engine sizes, horsepower, and designs. One common component is motor oil that is needed to keep the engine lubricated and running smoothly. Over time, much like in a car's engine, buildup can clog the engine components and heat can cause some oil to burn off. So oil in a mower needs to be changed periodically to keep the engine in good condition. This should be done at least once per year.

Make sure the lawnmower is turned off. If recently used, wait until the mower engine is cool to the touch before proceeding.

Locate the oil drain plug on the lower section of the lawnmower engine. Some lawnmowers lack this plug. If the plug is present, position the bucket or oil pan directly underneath the plug and pull the plug. If there is no drain plug, proceed to next step.

Remove the oil filling cap (one will be marked fuel, one oil). Position the oil tray or bucket on the side of the mower that does not have the air filter on it.

Carefully lift and tilt the lawn mower until oil begins pouring out of the oil filling opening into the tray or bucket. Continue tilting until the oil flows freely out. Allow the oil to fully drain which may take a few minutes.

Wipe down the dipstick if one if present on the oil cap. Inspect the dipstick for type of oil and amount. You can also check labeling on the mower or mower manual for the type of oil needed and the amounts.

Slowly pour some oil into the exposed oil fill opening. Stop every so often, insert the dipstick and remove. Inspect the "fill line" on the dipstick. If the oil level is at the line, stop filling. If not, wipe the dipstick with a rag, add more oil, and check again. If there is no dipstick pour the indicated amount listed on the mower or manual into the oil fill opening.

Replace the cap tightly. Press the "prime" button on the side of the engine if the mower has one before starting the mower.

Consider changing your air filter too at the same time.

Do not touch the engine or replace oil while the mower is hot. This can cause burns and injury due to hot metal and hot liquids such as oil and gas.
