Why certainly deal explorer! When mixing two-stroke petrol for things like lawnmowers, chainsaws or small engines, it's important to use the right amount of oil. Most manufacturers recommend around 3% oil to petrol, which means for every 1 litre of fuel you add 30ml (1 ounce) of two-stroke oil. Using too little oil can damage engine parts, while too much oil wastes fuel and money. Always check the owner's manual for the specific machine too, as requirements may vary slightly. Let me know if you need any other advice finding the right two-stroke oil for the task.
