I have a couple of questions:
My first is, am I supposed to drive my engine hard? For example, step on the gas and pass people, do WOT twice a month, and take it out on the highway. Or do I drive it like I have been, like a granny (for MPG's, and man does this car get GREAT gas mileage for a V8).
My second question is, should I flush the coolant every 50,000 miles or is it safe to do it every 100,000 miles?
