Seen in Seattle today. We're going to see $10/gallon before this is over. I guarantee it.
@Lana you use 87 octane over there? jeez
@outfrost I'm not well versed enough on the various types of fuel. Is 87 considered high? Low?

@Lana i'd think it's quite low. in Poland and Germany the baseline standard is 95 (and the "premium" whatever is 98), i remember being surprised to see 91 in Czechia but it's been a long time and idk if they still sell that

i *believe* higher octane number is better, since it tends to combust more efficiently in modern engines

@outfrost
Higher octane means higher compression ratio since the fuel is less susceptible to self-ignition. Higher compression ratio means higher performance. But the compression ratio is set in when the engine is casted, you cannot change it. Most cars can use 95 or 98 indifferently, there will just be a small difference in fuel consumption.
