ProGlide Extreme 15W-40 CK-4

Since the first Diesel engine, improvements in design and power output proceeded at an exponential pace quickly replacing steam as the preferred method for the movement of heavy loads. In recent times increased power output, reduced fuel consumption, long drain intervals and emission reduction systems has placed considerable pressure on Diesel Engine Oils to protect critical engine components.
To meet the challenges of technological advancements in Diesel Engine design Atlantic Oil has developed Pro Glide Extreme 15W-40 CK-4. Pro Glide Extreme has been tested to meet the new Caterpillar Oil Aeration Test (COAT)(1) critical for long drain intervals and the Mack T13 Lubricant Test(2) essential to meet the new API CK-4 specification. Pro Glide Extreme is fully backward compatible to Atlantic’s Pro Diesel 15W-40 CJ-4 and suitable for use in all vehicles requiring API: CI-4 and CJ-4.

(1) COAT, the new test for API CK-4 is a 50 hour engine test which evaluates aeration performance of a lubricant when run on Caterpillar C13 engines at idle conditions. The aeration is calculated throughout the test by using continuously measured lubricant density. The COAT replaces the aeration measurement provided by the EOAT for CH-4, CI-4 and CJ-4. Atlantic Pro Glide Extreme provides superior aeration performance that exceeds the requirements of COAT.
(2) The Mack T13 test is a 360 hour evaluation of the lubricants ability to resist oxidation and viscosity increase. The goal is to provide extended drain intervals in modern engine technology. The test is performed using a Mack MP8 engine at 1500 RPM and 2200 Nm of torque. Atlantic Pro Glide Extreme exceeds the new oxidation resistance requirements of the new CK-4 specification.
