    "The consensus is to check the owner’s manual first".

    Maybe the Feds should mandate that when folks buy a new car that before they drive it off the lot that they state that they have indeed read the owners manual by signing a disclaimer form ;-)

    I say if they want to take the chance with lower horsepower, engine knock and possible engine damage....Go for it. It's their vehicle and THEIR repair bills when the time comes to repair the damage done by their "cheaper gas experiment"!

    I will only use premium when I hear pinging under load (easily terminated by backing off the accelerator) or see subpar mileage numbers. So far, midgrade is plenty good enough for anything but an ultra high performance car, which I've never owned.

    I read a blog a while ago where someone put 87 octane in a Lancer Evo. No damage, but it immediately turned on the check engine light. In the end if you can't afford the gas, don't buy the car. That is why I have the 2010 Camaro V6 not the V8. I used 87 octane on a 2002 Z28 and destroyed the engine. Lesson learned.
