Be sure to add a bottle of BONZÍ Break-in Oil - it is formulated to get the max performance out of your stock or modified engine by properly seating the ring to the cylinder through what is known as a scuffing process.
Most 100% synthetic oils are so slick that they do not allow this process or take an extremely long time to do so.

With just mixed 5 ounces to a gallon, it allows for complete break-in in just one gallon.
