Rob, Lang et al. In 1981 I bought a brand new Chev Caprice Classic. I had installed a 77 liter propane tank in the large trunk. A brushed aluminum lockable access door for filling, and appropriate dash switches completed the ensemble.
At the time, and also during the same time to which Rob refers, efforts were made to encourage such dual conversions. Heavy subsidies for LPG meant a 0.13 per liter cost.
Yes, performance was down about 10-15%.
Yes, filling stations were far and few between.
Yes, cold weather starts were a bitch.
But if one had dual fuel, no sweat. Start on regular in the AM, run on LPG during the day, shut down on regular.
The military, bless their hearts, went total LPG for, primarily the usual inter base pedal runs and staff car routes which, through experience, had authorized regular gas refill stations located en-route.
With a lower performance profile, recovery calls started coming in because vehicles were stranded with out-of-fuel conditions. Quel surprise!
An expensive exercise indeed.
Any lessons learned, I wonder?
