Nobody is kidding about a 7500 mile oil change interval, if it was a diesel you could go even further provided the oil was clean. The API sticker on the back of motor oils certifies that the oil will last 7500 miles without losing viscosity under normal operating conditions. If the engine is overheated, then oil should be changed. I change my oil when it's dirty on both of our vehicles, but that's likely to be closer to 5k miles than 10k miles. I use Ford's oil.
