For two-stroke engines, whether for motorcycles, chainsaws, or scooters, it is very important to use the correct fuel-to-oil ratio of 24:1.
What does 24:1 mean
A 24:1 ratio means 24 parts fuel to one part two-stroke oil. For example, add 1 liter of oil to 24 liters of fuel. This ensures good lubrication, smooth performance, and long engine life.
