When should the engine oil be checked and changed?
All 4-stroke petrol devices from Einhell are supplied with a special service booklet that lists exactly how and when you should maintain your device. For example, an oil check should be carried out before each use, in the same way you should also check how much petrol you have left in the tank. You check the oil the same as you would in a car: Pull the dipstick out of the filler neck, wipe it and insert it again as far as it will go. When you pull the dipstick out of the filler neck again, the oil level should be visible between the minimum and maximum line.
When changing the oil, remember the following: Ideally, the first engine oil change should be after the first 20 hours of use of your petrol device. You can then change the engine oil after every 50 operating hours. How exactly to do this can be found as a step-by-step guide in your user manual.
In order to keep track of the oil changes and other maintenance work such as replacing spark plugs or cleaning the air filters, you can make a clear note of the times and later add them to your logbook so that you have a clear record.
How do I find the right engine oil?
Choosing the right engine oil always depends on the outside temperature at which you want to work with your device. While you usually work with petrol lawn mowers in summer, when it can get very warm in Germany, for example, you will need another special engine oil for an electricity generator that you might want to use in winter in particular. The choice of engine oil is therefore always regional and seasonal, so depends on the location and time of year, or on the outside temperatures. Whether an engine oil is suitable also depends on the type of fuel used in your device, i.e. whether it is diesel or petrol. You will find additional information on the recommended type of engine oil in the operating instructions for your device.
Incidentally, you should be careful if the oil is stored for too long! In the sealed original packaging, the engine oil can easily be kept for three to five years, but then chemical additives could become detached in it. In particular, partially synthetic and fully synthetic oils then lose their functionality in the long term. In case of doubt, you should buy new engine oil to get maximum performance and longevity out of your device.
Extra tip: Engine oil for 2-stroke engines
If you work with a 2-stroke device such as a petrol chainsaw or hedge trimmer, you should make absolutely sure that you buy a high-quality engine oil. In addition, the right mixing ratio is important here, because the fuel and oil must be mixed in these devices. You can read what type of oil and fuel you are allowed to use in the operating instructions. You will also find the mixing ratio in the booklet, which you should make sure to keep in a safe place. Often a mixing bottle is already included in delivery, and you can use this to easily establish the specified mixing ratio. For example, a ratio of 1:40 means one part of oil per 40 parts of petrol.
In 2-stroke petrol devices such as chainsaws or hedge trimmers the petrol-oil mixing ratio is crucial.
