What happens if you overfill your engine with oil

Changing the oil in the engine on time is an important part of engine maintenance. The engine’s moving parts require permanent lubrication, otherwise there is increased wear and the risk of corrosion. The amount of oil you need to add to an engine varies depending on its model. This information is stated in the vehicle’s technical operating book.

Control the amount of oil in the engine by using the dipstick, which has a mark “minimum” and “maximum” allowable amount of lubrication. But there are cases when drivers pour more oil into the engine than required. In this article we will consider what to do in such a situation, and how dangerous it is.

How to change the oil in a lawnmower?

First, check the oil level on the dipstick. The oil level on the dipstick should be between the two holes on the dipstick. Overfilling the engine can be just as bad as using old oil, so check the dipstick level regularly.

Then determine how to drain the oil from the lawnmower. This can be done through the oil dipstick tube, the drain plug, or with an oil sump. It’s time to drain the oil from there:

Run the mower engine for 15 minutes to warm up the oil (be sure to remove any dirty debris from the engine)

Shut off the engine and disconnect the spark plug wire

Drain the gas from the lawnmower OR place a plastic sandwich bag over the gas tank and screw the cap on to prevent leakage.

LAWNMOWER OIL Change the Simple Way ( no wrenches ! )

Insert the oil pan tube and begin pumping oil out of the engine

After you’ve removed all the old oil and placed it in a container, set the container aside and after you’re done changing the oil, take that container to your nearest dealer where they can recycle your old oil.

You can now pour in clean new oil. Refer to your operator’s manual to determine what oil is best for your engine. In this video, we used Briggs Stratton SAE 30 oil, which can be used for most small engines. After you finish pouring in the new oil, insert the dipstick into the tube and make sure the oil level is correct. When the oil reaches the correct level, screw on the oil dipstick cap, pour in new fuel if you removed it, and then reconnect the spark plug wire.

Simple instructions for changing the oil in a Briggs Stratton or other manufacturer’s engine.

Disconnect the wire leading to the spark plug before doing any maintenance on the lawnmower.

Use a hand pump to siphon gasoline from the tank. This will keep the gasoline from spilling onto the mower and prevent a fire that could start from the spark plug. A damaged spark plug wire or spark plug itself can cause fuel spilled on the base of the mower to ignite.

Locate the oil plug under the base of the mower. Most are square and fit a 10mm wrench. It could also just be a plug or bolt.

Support or hold the mower while you loosen the oil plug with a wrench. Do not forget to place a container under the base of the mower for the oil to be drained.

After the last drop of oil has drained out, put the oil plug or bolt back in place, but don’t tighten or seal it yet. Use the funnel to pour the drained oil into a bottle or any other container suitable for sending it for recycling. Local utilities must do this recycling.

Once the plug is closed and sealed, prepare new oil to pour it through the filler hole to the correct level. Some mowers have the fill hole on top where the oil dipstick is, while others have it at the bottom on the base near the engine. This lawnmower does not have an oil dipstick. it must be filled with oil through the oil cap almost to the neck. Use standard 10w30 or 5w30 engine oil.

Check that the oil cap is put on the filler hole and then fill the gas tank and put the wire on the spark plug.

The process of emptying the mower

You will need to start by running the lawnmower engine for a few minutes to the heat engine oil and make it well fluid. This will make it easier to remove the oil. A drain pump, whether it’s manual or battery-operated, is a tool that will make the task of emptying much less painful and more efficient. If you don’t have this accessory, you’ll need to tilt your mower to change all the oil. Recall that if you tilt it too much, you risk drowning the engine: oil can enter both the cylinder and the exhaust. This could end up damaging your lawnmower. If this happens by accident, a thick cloud of smoke will come out when you restart the mower. To avoid these kinds of problems, we strongly recommend that you use a drain pump. An inexpensive accessory that you will find in all stores.

After you have drained all the oil from the crankcase, you can pour in new and clean oil, making sure that the latter is suitable for the engine of your lawnmower. You should be careful not to exceed the prescribed dose and be sure to change the oil filter if your mower has one. Also be careful not to add too much oil! In this case, you will need to drain the excess, because too much oil in the engine can cause overheating as well as poor mechanical lubrication. This will generate severe engine damage.

owner’s manual

A step-by-step description of the steps and following the instructions will ensure that the tool works for a long time. It requires:

  • Check for fuel and lubricants (gasoline and oil), for electric models for cable damage.
  • Only specialists should sharpen the cutting blade.
  • If damage is found, take it for diagnosis.
  • Turn off the unit when you stop mowing.
  • Level the ground so that the blades do not become dull.
  • Move the mower slowly and forward.
  • Use a grass trimmer or trimmer near walls and fences to prevent damage to the blade
  • Discard the electric model if there is dew or rain. Use only in dry areas.

Important! Be sure to follow safety rules, so as not to harm your health and health of your loved ones. Electric lawnmowers are only used in dry areas

Electric lawnmowers are only used in dry areas.

Lubricants and fuel

According to the manual, the mtd lawnmower should only be started after checking the availability of fuel and lubricants. For lawnmowers, trimmers and brush cutters, a special engine oil for a two-stroke engine with air cooling system is used.

If the cooling system is rare, it will not work. The container with this oil must be labeled “for garden equipment”. Usually the ratio of oil to gasoline in the mixture is 2%: 20 grams of oil are added to 1 liter of gasoline. But it is different, depending on performance. Before you start, you need to find out.

Starting and running

The first thing to do is to read the manual carefully. Next:

  • Open the fuel filler cap, refill the fuel tank to the mark and check the oil level through the cap with a picture or “oil” sign;
  • degrease the fuel pump;
  • check the spark plugs near the engine;
  • open the choke and move it to the middle or extreme position for normal gasoline access;
  • Pull the cord sharply; sometimes it may take several tries.

Note! Since most new models come with a safety switch, it is important to keep it on when starting the tool. If it is inaccessible, make sure it is in a stable position

Remove any grass residue from the blade and body during operation. Product should be stored in a dry, heated area. Also keep the engine from overheating.

Typical faults

Overheating can cause malfunctions.

Typical abnormalities in the operation of the lawnmower can be:

  • Stranger sounds, knocking: tighten bolts.
  • Strong vibration: tighten bolts and see if the blade works.
  • A wheezing sound indicates a foreign body that should be removed by pausing.
  • Rough cuts can be corrected by sharpening or replacing blades.
  • Front wheel drive stop: adjust clutch cable tension.
  • When the engine stops after starting, they check the oil level or start stuck items by hand or call a garden tool repair service.
  • Mower off: check spark plugs and fuel.

There may also be other problems, including wear and tear or factory defects.

Much depends on proper care and maintenance of the garden tool. Then the daunting task of creating a beautiful lawn is solved very successfully with reliable equipment.

It will (probably) not stop suddenly and refuse to restart after 5 hours of use, but it is recommended to follow the recommended cycle: parts in new engines are often not ground perfectly smooth like your new engine turns these rough bits knock or cut paths for themselves, leaving little bits of metal in the oil. If you don’t get rid of them by oil changes, they can cause excessive engine wear.

Depending on your mower, you can either drain the oil from the bottom or tip the mower over and drain it from the top from the same hole where you pour fresh oil (the worst part of this. lifting and tilting the mower over the pan, but much easier if you have someone to help).


When I bought the house, I bought a new mower and snow blower. At the initial oil change for both you might have seen little “sparking” bits in the oil. So yes, the initial oil change is important. After that first time of the season it’s the norm. Maybe 2-3 times a season if you mow often or it takes a long time to mow your yard.


I usually change mine every year, and I do 1/2 acre in the summer in Florida. But then again, I use Mobil one and have a cheap mower.


After the initial change (which is important for a new engine for the reasons described. and most simple lawnmowers do not have a filter) change it before planting all winter. It’s good practice, to say the least. Much better than at the beginning of the season. Which would mean it’s been sitting in dirty oil all winter since last year.


Electric and gasoline lawn mowers should be stored indoors, at optimum air temperature ( not too high and not minus). The room must be kept free of moisture, wind, rain, snow. Be sure to limit access to animals and children there. It also needs to be well cleaned as dirt tends to stick to it and that causes the rubber parts to deteriorate, the plastic to age and the metal mechanisms to corrode.

What kind of engine does a Husqvarna race mower have??

This 46-inch Husqvarna mower has a Kawasaki 2-cylinder engine with an automatic drive system and an electric PTO. It features a comfortable seat with a high back and a flush hole, as well as quick-change cutting blades that require no tools.

A drain plug is a large nut or plug located under the oil pan on the underside of the engine. If you can’t get to the oil drain plug easily, you either have to climb under the car to get to it or lift the car.
