Yeah, but you're just lying to yourself. Everyone else will hear the mighty roar of an oil burner.
My biggest problem is that I drive a stick, and shift by sound and feel. If I can't hear the real engine, then that just doesn't work for me. And for the record, I often turn off the radio, and forget to turn it on for months...
