Hot Shot’s Secret has expanded the Black Diamond Outlaw engine oil family to include a 10w-30 viscosity. The 100% full PAO synthetic based engine oil contains extreme pressure additives, three times the amount of zinc of traditional CK-4 oils, and antimony levels over 400 ppm for improved film strength and protection, the company stated. The new viscosity is ideal for heavy-duty trucks, ag, construction, and industrial equipment where increased protection is needed. It offers reduced noise and vibration, extended oil change intervals, and a fuel economy gain of up to 3%.
