Answer :

LPG is used as a fuel for petrol engine, because of its following advantages 

1. It is cheaper than petrol 2. It is highly detonation resistant and does not pre-ignite easily. 3. It gives better manifold distribution and mixes easily with air. 4. Residue and oil contamination is small as it burns cleanly: implies longer lubricating oil change period. 5. LPG is lead free – implies- less exhaust emission. 6. Life of spark plug is increased. 7. LPG has a higher octane rating than petrol. 8. It meets emission norms 9. It can be transported easily to remote places by road and also by rail. 10. It results in increased engine life and smoother engine performance. 11. Crankcase oil dilution is small. So, oil replacement frequency is reduced. 12. Low engine deposits reduce the cost of maintenance. 13. Engine need not be modified. LPG kits are readily available (even for MPFI engines) and the kit cost is mostly affordable.
