This is the product of choice for optimal winter operation. Diesel Fuel Supplement® +Cetane Boost® contains the most effective antigel additive package available in the diesel industry - no blending with No.1 diesel or kerosene is needed to achieve maximum winter protection. Diesel Fuel Supplement® +Cetane Boost® keeps fuel injectors clean and boosts cetane up to 4 numbers for faster cold starts and a smoother running engine.
While it is preferable to use Diesel Kleen® +Cetane Boost® in non-winter months for maximum injector clean-up and a cetane boost of 6 numbers, Diesel Fuel Supplement® +Cetane Boost® can be used on a year-around basis. Although Diesel Fuel Supplement® +Cetane Boost® is an antigel, it will not harm your engine to use year-around.
