Are you driving a 2-stroke scooter without automatic oil pump? Then you have to mix the correct ratio of fuel and oil. This is essential to make your engine run properly and prevent damage. In this blog we explain how to do this and what you should pay attention to.
Why do you have to mix?
A 2-stroke engine does not have a separate lubrication system such as a 4-stroke engine. The oil is therefore mixed directly with the fuel and ensures the lubrication of the moving parts in the engine. Without the correct amount of oil, your engine can get stuck, while too much oil can lead to smoke development and cabbage deposit.
Which mixing ratio should you use?
The mixing ratio depends on the type of scooter and the manufacturer's recommendations. The most common mixing ratios are:
-
1:50 (1 part oil on 50 parts of gasoline) - This means that you add 20 ml of oil per liter of gasoline. This is the standard for most modern 2-stroke scooters.
-
1:40 (1 part oil on 40 parts of gasoline) - This means 25 ml of oil per liter of gasoline. This is often used in older or heavier loaded engines.
Always check your scooter's maintenance book to find out the exact mixing ratio.
Step-by-step manual
-
Use the correct oil Always use high-quality 2-stroke oil that is suitable for your scooter. There are mineral, semi-synthetic and completely synthetic oils. For modern scooters, a semi-synthetic or fully synthetic oil is often the best choice.
-
Measure the oil accurately Use a measuring cup to measure the correct amount of oil. An incorrect amount can cause problems.
-
Mix the oil with the gasoline First pour the oil into a jerry can and then add the gasoline. Shake the jerry can well so that the oil spreads evenly.
-
Tank your scooter Fill the tank of your scooter with the mixed mixture. Make sure that you do not keep the mixture for too long, because over time the oil can separate itself from the gasoline.
Extra tips
-
Use a separate jerry can for mixed fuel to prevent confusion.
-
Don't mix too much in one go; Fresh mixture is always better.
-
Note the quality of the gasoline and oil to guarantee a long service life of your scooter.
-
Regularly check the spark plug and exhaust for pollution.
By mixing your 2-stroke scooter yourself, you ensure optimum performance and you prevent expensive repairs. Good luck with mixing and lots of driving pleasure!
