XE285HL in 360
We have 4 readily available pump octanes available here: 91, 94, 95 & 98. 94 contains 10% Eth, all the rest are non-Eth. Selected service stations have E 85, but I am not sure of it's octane rating or whether it is marked on the pump.
My understanding is that our #s are 3-4 numbers higher than yours. So your 87 is close to our 91.
