Yeah, many times in a heads up, a record attempt, or trying to move up the qualifying sheet, not unusual for a Stock Eliminator racer to drop some oil, or put in some super light oil, to pick up some performance. That said that "freed up" HP goes away pretty quickly once the bearings get starved for oil. If you could keep the oil several inches away the the spinning crankshaft, you would certainly greatly reduce windage and free up some power, but other than a jacked up 4x4 truck, a oil pan with a 12" + deep sump dragging on the ground just ain`t very practical. When I tried running low oil level in my 85 Mustang Stockers 302, it certainly ran a bit quicker and faster, but with the rear sump pan, even moderate braking caused the oil pressure gauge to drop an uncomfortable amount. Same with superlight oil, I ran some Royal Purple Racing 11 oil, about 0W15. It poured like water, even cold, but even though it only lost a bit of oil pressure, I just didn`t feel comfortable leaving that oil in more than a few passes.
