Klotz Synthetic Uplon fuel lubricant will challenge and outrun the competition in many ways. Added seal conditioners maintain constant fuel pressure and prevent lean-out conditions. It increases horsepower by reducing power-robbing friction and its anti-wear chemistry reduces valve and valve guide wear. Uplon also improves the ring seal for higher combustion chamber pressure and power and eliminates the need to use after-run lubricant.
