Tom,
I have a 2005 Hyundai and the book says to use 87octane middle-grade gas. What would happen if I use regular grade?

Answer:
Over time a condition called "pre-ignition" or "engine knock" will occur. With this condition, when the fuel enters the engine it pre-ignites, which causes constant hammering of the tops of the pistons, cylinder head face, and valves. Eventually, major engine damage becomes evident and major repair becomes necessary. Your choice? Cheap gas or engine replacement. Don't be 'penny wise and pound foolish.'
