Annual oil change is good - every 25 hours of operation is better
Freshly filled in, engine oil in the crankcase shimmers gold to amber. Heat, dirt, dust and grass residues darken the oil, which noticeably affects its lubricity. The more difficult the conditions when mowing the lawn, the more quickly lawnmower oil loses its effectiveness. The following intervals for an oil change have therefore proven effective in practice:
- Commercially available 4-stroke lawn mower with normal use: once a year, ideally in spring
- Heavy-duty petrol mower: every 25 operating hours
- Newly run-in lawnmower: first oil change after 5 to 6 hours of operation

If you have one of the now rare lawnmower types with a 2-stroke engine, the oil is burned at the same time as the gasoline, so that an oil change is not part of the care and maintenance program.
Change lawnmower oil correctly - you should pay attention to this
An oil change on the lawnmower should always be carried out on the warm engine, because in this way more suspended particles are removed than with a cold engine. In addition to the right type of oil, a collecting container is the most important utensil. How to proceed professionally:
- Start the lawn mower and let it run for a few minutes
- Stop the engine and pull out the spark plug connector
- Place a collecting container under the oil pan
- Unscrew the oil drain screw counterclockwise
- Drain all of the used oil into the collecting container
Then tighten the oil drain screw tightly in a clockwise direction. Now open the filler neck. Using a funnel, fill in the fresh oil to just below the maximum mark in the tank and put the lid on. Restart the mower to check for leaks while the engine is idling.
Tips
After changing the oil, clean your lawnmower carefully. Even the smallest residue on the cutting deck burns up as blue-white smoke the next time you mow the lawn and gives you a real scare. Therefore, wipe the device thoroughly with a damp cloth and a cleaner that dissolves grease.
