What Type And How Much Oil For My Lawn Mower

Changing the Oil in a Riding Lawn Mower

Quick Links:

Before you are able to change the lawn mower oil on your Briggs & Stratton® small engine, its important to understand the oil type and capacity required. The type of equipment you use, the engine within, and the temperature outside determines what type of oil to use, how much you need and the cost of the oil. Use the Oil Finder tool below to find the right oil for you.

Step : Preparation The Husqvarna Lawnmower

Park the mower at a place that can deal with an accidental oil spill. When you remove the oil, it is always possible that some of it will spill on the ground. Then let the Husqvarna lawnmower run for 10 to 15 minutes. That will warm up the oil, and makes it much easier to replace. It also makes checking the oil level easier.

Step : Check The Oil Level

Before starting the engine, is it a good idea to check the oil level. You can do this as follow:

  • Flat area: Make sure the lawnmower is parked on a leveled site.
  • Open the fill cap: Find the fill cap, remove it, and clean it with a cloth.
  • Clean: thoroughly clean the cap and the area around the crankcase.
  • Check the dipstick: Check the oil level by re-inserting the dipstick. When you take the dipstick out, you will see the thick oil layer attached to it. If its near the low marking, your mower needs more oil. If its been some time since you last changed the oil, you should completely change it instead of just topping up on what was already there.
  • Add oil if needed: If the level is not ok, add oil and check again. If the level is higher than it should, you have to remove some of the excess oil.

Change The Oil Filter

Oil filters keep the lubricant from being infiltrated by larger pieces of dirt and debris. If debris is allowed through the filter, it will cause excessive engine wear to your mower.

While the filter may not require changing every time you perform a change, it does warrant checking it every time.


A good rule of thumb is that you should change the filter at least once a year, but this is a basic guideline. Refer to your owners manual for information about the frequency at which you should change the filter specific to your piece of equipment.

Once you have located the filter, use your hands or the pipe/filter wrench to remove the filter from the engine.

After you have removed the filter, you should clean the area where the filter attaches to the mower as well as the seal on the new oil filter.

Wipe some new engine lubricant onto a shop rag and lubricate the seal on the new filter. Place the new filter onto the adaptor and tighten into pace using the pipe/filter wrench or your hands.

Step One: Getting Started


Begin by starting your lawn mowers engine to let it warm up for about 60 seconds. After turning off the engine, disconnect the spark plug wire to ensure your lawn mower doesnt accidentally start while youre working.

Step Two: Draining the Oil

If youre changing the oil on a push mower, begin by propping up the mower deck so the spark plug is facing up. Place the oil-safe container underneath the mower. With a socket wrench, unscrew the oil plug counterclockwise until oil can escape. Empty the oil from your mower into an oil-safe container.

Step Three: Replacing the Oil Filter

Begin by locating the oil filter on your lawn mower or tractor. Twist the oil filter counterclockwise to remove it. Inspect the seal of the oil filter for any dirt or debris and clean it off. Using new engine oil, lubricate the clean sealing gasket so that it appears clean. Once it appears clean and well-lubricated, place the new oil filter into the filter adapter and screw it back into place by hand. Using a wrench, tighten the oil filter.

How To Check Oil Level

Make it a habit to check the oil level and appearance each time you’re about to start a small engine. Checking the oil while the engine is cold and most of the oil is in the crankcase yields the most accurate reading.

For oil checking procedures on lawnmower applications, please watch our “Checking Engine Oil – Lawnmower Engine” video:


  • Step 1: Locate the oil fill cap on the crankcase to start. Fill cap locations vary, depending on the make and model of your engine.
  • On newer models, look for an oil can symbol or the word “oil” or “fill” stamped on the plug.
  • On small tractors, you may have to lift the hood to locate this cap.
  • Some engines contain either an extended oil fill tube or a standard fill hole with a dipstick for inspection.
  • Others require you to remove the fill cap to check that the oil is at the fill line or the top of the fill hole.
  • Step 2: Clean the Crankcase: To prevent dirt and debris from falling into the crankcase, use a clean cloth to wipe the area clean before removing the cap.
  • Step 3: Inspect the Oil. If there is no dipstick, dab the oil with a clean tip of the cloth to inspect the oil. If the engine includes a dipstick cap, remove the dipstick and wipe it with a clean cloth.
  • To ensure an accurate reading, reinsert the dipstick completely. If the dipstick cap is a screw-in type, ensure an accurate reading by screwing in all the way before removing it to check the level.
  • Then, remove it again and check the oil level.

Run the engine for about 15 minutes, then place the mower on a flat surface. Also, remember to clean the working area and prepare the oil drain pan. You may use towels to wipe the oil change area. If you use the tilt method, remember to lay some newspapers or cardboard to catch oil spillage.

Disconnecting the spark plug wire also comes first before any lawn mower maintenance for safety. Keep the spark plug away from the mower to avoid unintended ignition and fire.

For the siphon method, insert the pump into the dipstick till it hits the engines bottom. Dip the other end of the pump into the oil drain pan and manipulate the pump handle to siphon out the oil manually.

Put the oil drain pan beneath the dipstick tube if you prefer the tilt method. Ensure that its on the opposite side of the air filter, so the old oil doesnt contaminate the filter. Keep leaning the mower while ensuring that the oil flows into the drain pan. Maintain the leaning posture until the flow reduces to a drip.

Once youre done draining the oil, carefully tilt the mower to return it to its upright position and let it rest on its wheels. Remove the pump if you were using the siphon method.
