Why do people speak when they don't know what they are talking about? I just.. I don't understand, quick lesson;
The number of Octane (the best fuel to handle compression) needed for best MPG is almost ALWAYS what the manufacturer tells you in your manual. For 2.4l and 2.0l Engines it recommends 91+ because they are high performance engines, the compression stroke (where the engine compresses a cylinder-full of air and gas into a much smaller volume before igniting it with a spark plug. ) in our vehicles recommends a compression ratio to keep the vehicle running smoothly. The octane rating of the gasoline you put in your car, tells you how much the fuel can be compressed before it spontaneously ignites. When it ignites from compression instead of the spark plugs, it causes knocking in the engine. Refer to the "DON'T USE CHEAP GAS, ON A HIGH PERFORMANCE ENGINE, YOU CHEAP MOTHE.." above or how they put it (more politticaly correct) "Use premium unleaded gasoline with a posted octane rating of 91 or higher." ANYWAYS back to what I was saying.. When you hear knocking, you are playing Russian roulette with your engine and unless you want to save "dollars" which *ahem* is causing worse mileage (BTW, because the compression ratio is too low and their is too much heptane [the other fuel used with Octane-> 87 octane, 13 heptane etc..). Well you are shaving "pennies" off, getting shittier gas mileage and potentially causing 1000's of dollars of damage to your engine.. oh and you are causing your vehicle to perform shitty.
If you want to use 87octane, get a prius. /thread

There is an extra nipple on the lsj.
