People who hate downtime and demand performance choose to fill up with Premium Dieselex-4—CountryMark’s premium on- and off-road diesel fuel. On a number of factors that contribute to quality, it truly excels. Discover why no other fuel brings more to the job, road or farm. Better still, it works hard season after season. Winter included.
Determined to keep those fuel injectors clean and minimize engine maintenance costs? It’s all about detergency. Our premium diesel fuels contain a unique deposit control detergency package. This fuel has been lab tested and field-proven to eliminate and prevent damaging deposits in today’s most complex engines.
Diesel engines new and old benefit from fuel with high cetane levels. The higher the cetane number, the faster the fuel ignites and the more completely it burns. This helps engines perform better, make less noise, and create fewer emissions. Our Premium Dieselex-4 is tested regularly and produces some of the highest cetane values found in the Midwest.
Advanced chemistry gives Premium Dieselex-4 enhanced lubricity. That simply means less wear and tear on injectors and injector pumps. Less wear and tear ultimately translates to less downtime and extended life for your fuel system. You can count on CountryMark Dieselex-4. It doesn’t just meet government lubricity standards, it exceeds them.
When you’re buying and storing a lot of fuel, you want to be sure its quality has lasting power. In a word, you need stability. CountryMark Premium Dieselex-4 contains a superior stability package that reduces the fuel deterioration process. This leads to longer fuel life and assured fuel performance.
Fuel Specifications | Typical Common Carrier #2 Diesel | Premium Dieselex-4 | Your Benefits With Premium Dieselex-4 |
Cetane Number | 40 | Cetane enhanced for maximum engine starting performance — 45 to 50 | Better engine performance, easier starts, less white smoke, less noise, lower emissions |
Lubricity | Basic lubricity package creates a larger wear scar — 520 micrometers | Superior lubricity package creates a smaller wear scar — 460 micrometers | Minimizes the wear and tear on injectors and injector pumps, which leads to less downtime and extended fuel system life |
Detergency | 85% of all diesel fuels on the market today contain no detergency package | Detergency package is proven to eliminate and prevent nozzle and internal injector deposits | Maximizes combustion efficiency, minimizes maintenance costs and helps eliminate downtime |
Stability | Stability package ensures months of product stability | Stability package ensures years of product stability | Reduces the fuel deterioration process, which leads to longer fuel life and assured fuel performance |
Colder weather isn’t kind to some diesel fuels, making them harder to ignite. Not so with Premium Dieselex-4. It’s seasonally blended to prevent fuel line freeze-ups and produce optimum winter performance. It also contains deicers designed to pick up and eliminate small amounts of water in the fuel as it’s burned. Cold-weather storage and stability are excellent, too. Our winter operability package prevents fuel from gelling in low temperatures.
Operators/Producers using typical #2 diesel may not even realize it’s happening. Hour by hour, deposits can grow slowly and reduce the engine’s power. Over a season or two, engines can suffer very real performance losses. Modern Tier 3 and 4 engines are even more susceptible. That’s why CountryMark Premium Dieselex-4 uses detergency to combat and control deposits. Together with its cetane level, lubricity and stability, it’s a complete choice.
