By the old octane rating method.
Today's 93 is equivalent to that.
Google will probably have a comparison factored between now and then.

Ok so if the new rating of 93 equals the old rating of 100 then I guess today’s gas is decent for the octane, it’s just missing the lead. Thanks, good to know. Thanks, Marc.
