the minimum and maximum ethanol on gasoline is also way higher here, which means more oil saved that can go to produce diesel, brazil is extremely depend on trucks for internal transportation of all goods, including goods that are exported, thus diesel cost has quite a high impact on the cost of everything here, even the relatively small increase here is quite impactful

one big side effect of the high ethanol is that a lot of old cars really don’t run well on it and can cause significant damage to their engines, and having way less energy per volume means more often refueling which can be quite annoying
