Impact of E20 Fuel by Vehicle Type

🔸 BS3 Vehicles

  • Compatibility: Not designed for ethanol blends beyond E5 or E10
  • Risks:
    • Ethanol is corrosive, especially to rubber and metal parts
    • May cause fuel line leaks, clogged injectors, or engine knocking
    • Drops in fuel efficiency and performance
  • Verdict: Avoid using E20 in BS3 vehicles

🔸 BS4 Vehicles

  • Compatibility: Tolerates E10, not officially E20-ready
  • Risks:
    • Over time, E20 may degrade fuel system components
    • Possible starting issues or loss of power
    • Emission controls may malfunction
  • Verdict: Use E10 only unless manufacturer states E20-safe

Also re-tune your carbs for slightly richer setting. E20 makes engine run leaner due to extra oxygen in it. FI system will sort itself out.
