The lower octane level you CAN run in a car the more performance you get because the fuel is igniting sooner. However engines like ours need to build up enough pressure before the fuel can ignite and therefore our cars need 91 octane. If you put 87 in our car the fuel will ignite too soon and cause knocking and if you put 94 in the car, the fuel is not igniting at the prime time I.E its actually delaying ignition.

Sibze, may I ask what qualifications you have to make your statement?

That's kind of like asking someone who isn't a doctor what qualifications they have to claim that eight glasses of water a day is good for you. It's fairly common knowledge - enough that you don't really need to be an expert to make the statement. A simple Google search should give you hundreds of articles on the topic...
