1. Improved Lubrication: Helps reduce friction between moving engine parts, reducing wear and tear.
2. Cleaner Engine Operation: Reduces carbon build-up and minimizes engine deposits.
3. Enhanced Performance: Can boost power output and improve throttle response.
4. Protection Against Corrosion: Helps to protect the engine from rust and corrosion.
5. Smoke Reduction: Some additives are formulated to lower the amount of exhaust smoke produced by 2T engines.
6. Extended Engine Life: Prevents excessive wear and tear, which can extend the overall lifespan of the engine.

These additives are often used in motorcycles, chainsaws, lawnmowers, and other small engines that rely on 2T oil for lubrication. The exact formulation can vary depending on the brand and intended use, but the overall purpose is to improve engine function and reliability.
