His CA 91 isn't much better then our 89, if at all.
+1 on the owners manual part
Your vehicle is designed to use “Regular” unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as
“Regular” with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended.
Premium fuel will provide improved performance.
