What Do CK-4 Oils Mean for Your Fleet?

CK-4 Diesel Motor Oils: Striking the Balance

• Enhanced protection: CK-4 oils offer improved protection against wear, deposits, and viscosity breakdown. This translates to increased engine life, reduced maintenance costs, and improved reliability for your fleet.
• Compatibility: CK-4 oils are compatible with engines using low-sulfur diesel and biodiesel blends up to B20. This flexibility ensures that your fleet can transition smoothly to more environmentally friendly fuels without compromising performance. CK-4 oils also have full backwards compatibility with older engine models, and these oils are available in all current grades. Though Ford and Motorcraft do not recommend CK-4 oils for their F-series diesel trucks, CK-4 oils will benefit most engines.
• Application versatility: Whether your trucks are deployed on highways or challenging off-road terrains, CK-4 oils are suitable for a wide array of applications. 

Making the Right Choice for Your Trucking Fleet 

Choosing a CK-4 motor oil depends on the composition of your trucking fleet and your operational priorities. If your fleet comprises a mix of older and newer engines, CK-4 oils may provide a balanced solution. The Shell Rotella^® T4, T5, and T6  product lines all meet the strict CK-4 requirements, and oftentimes, deliver better than the maximum wear requirements making them great for on-highway fleets, general haul, construction, agriculture, public-transport operators and diesel pick-up trucks.

How Will Consumers Save Money?

CK-4 oils promise greater fuel economy and a longer oil lifespan. Consumers will get longer drain intervals due to a more stable oil with strong, protective additives. 

• CK-4 oils run hotter. Today’s engines run at higher temperatures, meaning vehicles need to have a higher HTHS (Higher Temperature High Shear) viscosity oil. CK-4 oils have improved shear stability to handle high stress conditions and maintain viscosity so that your oil, and your engine, won’t fail.
• One of the greatest benefits of both oils is their strong resistance to oxidation. Oxidation increases oil viscosity by creating sludge, leading to premature oil changes and maintenance costs. These new oils, however, promote stability and cleanliness under heavy-duty conditions.
• CK-4 oils have better aeration control than previous CJ-4 oils. High-speed engine operations cause air bubbles to become trapped in engine oil, but the new oil varieties are better able to release air bubbles so your oil won’t be compromised.

Another option for even more savings is buying Keller-Heartt’s own Truegard oils which provide the same level of protection as comparable blends and full synthetics:
