Could have sworn I remembered a video of a sedan, maybe in Russia, that had allegedly been converted to run on something like propane and the tanks were stored in the trunk. Sure this was more affordable than regular vehicle fuel, but when it got rear-ended… it exploded!
YouTube isn’t full of these videos by any means so maybe it’s safer than I thought?
it’s very common in turkey italy mexico and a couple other countries that sell lpg (propane-butane mix) at lower prices than gasoline, nothing explodes these tanks need to be certified (varies by country) and gasoline is already flammable so nbd
in a city where i live most of taxis are hybrids modified to run on lpg so it has to be both safe and durable
its a mix that varies by season because in winter higher pressure at the same temperature is needed, and in summer the opposite. and also in winter gasoline has a little butane dissolved, because it’s cheaper and has high octane number, and makes engine startup easier. its a bit complicated but it works
Are you familiar with the way California has winter and summer blends? I think it’s a slightly different principle, focused on being environmentally friendly in the summer when it shouldn’t be too hard for engines to start.
every country has these seasonal changes (except those near equator) both for gasoline diesel and lpg and this is before we get into renewable components
gasoline and lpg are changed for the same reason, it is to keep vapor pressure at the same temperature lower in summer and higher in winter. too low and it’s hard to start, too high and volatile components bubble out = gasoline degrades and makes smog in the city. diesel is more complicated because it gels out at lower temperatures but how exactly this happens depending on several things, and mitigations are different

Propane-butane, interesting!
Oh good

Ah!
