The US uses a slightly different Octane rating system that averages slightly lower than the more common RON. The system they use averages RON with MON which is measured under different engine conditions. The pump is labeled with (R+M)/2 to indicate this in the image. According to Wikipedia, 88 is equivalent to 95 RON.
The US uses a weird mix of RON and MON ratings (printed on the buttons) - 88 on their rating would be 91 RON, which is still very low for more modern engines, but not gut-wrenching at least.
Unleaded 88, wtf ? Does the US have gasoline with such a low octane ? or is it the price in inch pounds per linear whatsadoodle ?

No idea why they feel the need to be different.
I still don’t understand, can you compare that to something completely arbitrary like bourbon, Coke or football ovals?
Not quite Everclear but stronger than Jack Daniel’s.
Damn, that actually makes sense
