Our GX® Full Synthetic API CK-4/SN, TBN 9 Heavy Duty Motor Oils SAE 15W40 are Diesel Engine Oils formulated with a premium 100% high-viscosity index synthetic base stock, plus a special additive package designed for superior protection against wear, corrosion, oxidation and varnish with superior anti-shear properties designed to meet 2017 model year on-highway and TIER-4 non-road exhaust emission standards as well as for previous model year diesel engines.


They provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil

aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear,

piston deposits, degradation of low- and high-temperature properties and soot-related viscosity increase.


Specially effective at sustaining emission control system durability where particulate filters

and other advanced after treatment systems are used.


In addition to API CK-4, these oils exceed the performance criteria of CJ-4, CI-4 with CI-4 Plus, CI-4,  

CH-4 and can effectively lubricate engines calling for those API Service Categories. 

Also recommended to be used where an API SN gasoline motor oil specification is required.
