I reckon LPG is a short term fix to a long term problem.
LPG is too inconsistent, it is a mixture of butane & propane that each fuel company mixes up to what they think is ideal. It also is a mix of naturally occurring gas & the gas bi-product of manufacturing petroleum products, hence the name Liquid Petroleum Gas.
There is no denying the fact that it is cheaper to run a vehicle on LPG, in the short term. However, long term the cost of maintenance is higher than an equivalent petrol vehicle. Air filters have to be change more frequently, more frequent inspections for fuel leaks, spark plug life is shorter, engine oil thickens so oil changes are more important, and the fuel tank is required by law to be tested every 10 years, this means removing the tank.
I have been told that the BA LPG engine has a problem of backfiring through the intake system. Ford could not come up with a suitable fix, so the air cleaner element for a LPG engine is different to a petrol engine, same size different material.
Diesel is the only alternative to cheap fuel that I can see. More diesel is produced per barrel of crude than petrol, the process to produce diesel is simpler than petrol, diesel engine advancement & refinement is a generation ahead of LPG (LPG has piggybacked petrol engine development).
But petrol engines sound so much better than diesel burners.
