I drive a 2007 Mazda RX8, but I fill up regular gas, not premium. Is this not good? I heard mixed answers, some people say its very bad and it will ruin the engine, others say it does not matter. I don't want to sound like a cheap guy driving an RX8, but with gas prices these days, and the amount of fuel this car drinks, I don't know if it is worth putting in premium. Thoughts?
