Abusing the engine is a completely meaningless phrase, because it can mean so many different things. 98Coupe says he beats the shit out of his car on a daily basis. But I bet he doesn't mash the gas pedal as soon as it fires.

Once the oil is circulating at full temperature, I don't consider WOT runs to the redline as abusive. But 2/3 throttle at 4000 rpm immediately after a cold startup in january, I consider that to be very abusive.
