Question

Which one is best petrol car or lpg car?

Answer 1

An LPG car will get about 10% or so less in gas economy. An engine running on LPG will last a lot longer though. Gasoline is an solvent and will disolve the thin layer of oil on the cylinders. LPG won't do this since it is not a solvent allowing the engine to last much longer. Also the engine will run cleaner requiring less oil and spark plug changes. I have a 1957 Ford tractor that was converted to propane when it was new and it still is running on original engine.
