Talk:Energy Saving

Energy Saving  In the Garage Use the Octane Level You Need. Your owner’s manual tells you the recommended octane level [regular (usually 87 octane), mid-grade (usually 89 octane), and premium (usually 92 or 93 octane)] for your car. For most cars, that’s regular octane. Unless your engine is knocking, buying a higher octane than your car needs is pouring money down the drain.

This is a money saving tip, but does it do anything about conserving energy or being more environmentally friendly? Do higher octanes do more damage to the environment during processing? Do lower octanes cause more pollution? I'm just posing the question, I do not know. But if it's just a money-saving tip, I don't think it belongs here.
