What amount of oil and petrol do you use to fill up a whipper snipper?

To fill up a whipper snipper, you typically use a pre-mixed fuel that combines oil and petrol in a specific ratio, often 40:1 or 50:1, depending on the manufacturer's specifications. For example, if using a 50:1 ratio, you would mix 2.5 ounces of oil with one gallon of petrol. Always refer to the owner's manual for the exact mixture ratio required for your specific model.
