Reformulated D-MO Oils

Reformulated D-MO Oils

The next generation of diesel engine technology has arrived and Co-op has you covered.

The reformulated CO-OP® D-MO® Oil is designed for use in all naturally aspirated, high-output and turbo-charged four-stroke diesel motors requiring the API CK-4 performance specification.

1. Why is a new diesel engine oil required?

New diesel engine oils have been reformulated to improve efficiencies within the engine in order to meet the tighter fuel economy and emission regulations that have been set.

2. Why is there a need for two diesel engine oil performance specifications, CK-4 and FA-4?

In order to achieve the new fuel efficiency standards for both on and off-road engines, the new performance specification was split into two categories:

  • Surpasses the previous diesel engine oil performance specification CJ-4
  • Fully backwards compatible
  • On and off-road engine compatible
  • Provides improved engine protection
  • Unique diesel engine oil performance specification
  • Limited backwards compatibility with specific OEMs
  • Designed for 2017 and newer on-road engines
  • Provides greater fuel economy for on-highway operations

*Note: At this time Co-op has not yet determined that having an FA-4 product is needed for our market.

3. What are the benefits of using the new D-MO CK-4 diesel engine oil?

The new D-MO CK-4 formula provides significant benefits in:

  • Durability and wear protection – Improved engine component protection
  • Contamination control –Maintains full oil flow in harsh operating conditions
  • Shear stability – Prevents oil thinning at higher temperatures
  • Viscosity loss prevention – Oil resists breaking down and remains in grade longer
  • Deposit formation protection – Prevention of sludge/deposits on pistons
  • Aeration control – Reduces oil foaming and prevents pump cavitation

These performance features add up to improved wear protection and longer engine life and can extend oil drain intervals, resulting in more kilometres being driven. D-MO CK-4 oil maintains its oil integrity in high-temperature and extreme operating conditions with exceptional thermal and oxidative stability. D-MO CK-4 oil is capable of withstanding the high temperature and stressful situations that occur with heavy load capacity hauling.

4. What are the licensing and testing requirements for the new diesel engine oil formulations?

To meet the new performance specifications, D-MO CK-4 oil has been rigorously tested to ensure that it not only meets the American Petroleum Institute (API) requirements, but has also undergone Original Equipment Manufacturer’s (OEM) field and lab tests to be fully licensed and approved for use in several OEM engines.
