For seriously cold weather, get seriously tough fuel.

Winter Master Road Master XL

Serious weather protection

Cenex Winterized Premium Diesel Fuels deliver the serious weather protection your diesel engines need — while optimizing power and engine performance. The advanced performance additive package allows for extreme-low-temperature operability.

Cenex Winterized Premium Diesel Fuel addresses the needs of new diesel engine technology with its proprietary additive package, including an injection stabilizer that meets the Tier IV Final EPA emission standards in 2014. Testing confirms that the upgraded injection stabilizer successfully removes and prevents internal diesel injector deposits (IDID), including carbonaceous, soap/metal carboxylates, and lacquer-type deposits.
