⚙️ Why Correct Fuel Oil Ratio Matters
Using the correct premix for 2-stroke engines keeps your machine powerful, clean, and long-lasting. An incorrect 2-stroke oil-to-gas ratio can lead to:
- ❌ Too little oil → Engine overheating, piston damage.
- ❌ Too much oil → Excess smoke, fouled plugs, poor combustion.
✅ Correct ratio ensures:
- Smooth acceleration and performance
- Longer engine life
- Better fuel economy
- Lower emissions
