An easy way to tell if your engine is having issues, or not, is to take a white piece of paper and catch the drippings from the stinger. If the oil is clear, it usualy means the engine is in good running order. If the drippings have flakes or fragments it usualy means something is rubbing or catching and should be looked at. If the drippings are grayish or gray, it is a good sign that the main bearing is on it's way out. If this is not taken care of soon, it will take out the tolerance between the crank and block and will not only cause tuning issues but the front bearing may also start leaking with no fix. Figured I would mention this 🙂
 
Fuel doesn't matter, if it's pink, the droppings will be pink too, blue, green whatever. Your looking at what's mixed in with the oil, that's what matters.
