Side note: is that a typo or do you really have 87 octane gasoline in the USA? Because it's 95 and 98 in the EU.

yes, but we use a different method of measuring than you do.

IIRC ours is the average of 2 different methods (it normally shows as R+M/2 on our pumps), whereas I believe the EU uses only the one that tends to be a lot higher (RON I think)

Most gas stations around me have 87, 89, and 91, and sometimes 93. I believe your octane numbers will be on average like 6 higher than ours for the same gas.

They're possibly different measures, RON vs MON. The wiki article has more including a photo of an offending US gasoline pump https://en.wikipedia.org/wiki/Octane_rating
