Most people do pp racing and along with that use the engine limiter. When you do an oil change you are not only bringing up the hp but also your torque. Now where this hurts you is the more torque you have the less hp you can run at the same pp. So many people go without, some even get their oil dirty purposely just so the car will run the least amount of torque possible at a certain pp.
