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

Ah!
