My Camaro doesn't "ping or knock" using the lower octane, So, my question is, is the higher octane really necessary?  |

"only" $1.50 more! stuff doesn't cost enough as it is! i love the car but it's a "pig" and we all know it! if gas gets any higher decisions will be made by quite a few people!..just sayin'
