Press Release

With a commitment to advancing the country's energy sector, Pakistan State Oil (PSO), the nation's largest energy company, has developed the first fully synthetic CK-4 graded heavy-duty diesel engine oil - DEO Max - based on API standards and the latest lubricant technology in the world.

DEO Max, the first of its kind in Pakistan, offers the following features:

  • Longer oil drain interval: Compared to previous API CJ-4 technology, DEO Max provides 60% better oxidation resistance to your engine, enhancing your engine's drain interval.
  • Improved engine life: Oil provides excellent detergency, ensuring deposits on engine parts are controlled even at high temperatures to extend engine life.
  • Reduced emissions: Low-SAPS additive technology extends the life of exhaust emission systems, which reduces environmental emissions.

Increasing concerns about its predecessor's (API CJ-4) inability to survive the aggressive and harsh operating environment of technically advanced engines brought forward the need for a new, improved and cost-efficient solution.

The CK-4 engine oil has already proven its performance track record since it was launched globally, providing robustness, reliability, and economic efficiency. Compared to its predecessor CJ-4, DEO Max extends the interval between oil changes by 60%.

In Pakistan, DEO Max has revolutionised the energy landscape with exceptional performance for modern and pre-dated heavy-duty diesel engines. Technology being used in DEO Max has passed strict performance tests to qualify where API CK-4, CJ-4, CI-4 Plus, CI-4 and CH-4 oils are recommended.

DEO Max is likewise suitable for low-emission diesel trucks and buses from North America, Europe, and Japan which are equipped with Euro 5 & Euro 6 engines. Diesel engine oil can also be used in off-highway vehicles and plants, such as agricultural equipment, port operations, mining and quarrying operations, as well as in stop-and-go vehicles like buses and waste collection trucks.

Now available nationwide

Featuring the world's most advanced additive, DEO Max is available at all retail forecourts, lubricant markets in the Hi-street segment, and in the B2B market.

In its mission to enhance Pakistan's fueling experience, PSO, the country's flag bearer, continues to introduce the latest and advanced technologies in every sphere of its operations.
