SKU 320021 Categories ,


TOP DOG® Indestructible 15W-40 is an uncompromising, next generation Heavy Duty Diesel Engine Oil containing Indestructible additive technology specifically designed to protect high powered, turbo charged Heavy Duty Diesel Engines. The unique formulation contains performance enhancing and superior wear protection technology that far exceeds the requirements of the new API CK-4 lubricant specification and previous specifications including API CJ-4. TOP DOG® Indestructible 15W-40 meets the majority of modern engine manufacturer’s specifications. It has been designed to significantly exceed the requirements of API CK-4, which is the latest Heavy Duty Diesel Engine Oil classification released in December 2016 by the American Petroleum Institute. Having a low SAPS level, TOP DOG® Indestructible 15W-40 is suitable for Heavy Duty Diesel Engines fitted with EGR (exhaust gas recirculation) systems and other exhaust after-treatment systems including Diesel Particulate Filters (DPF’s) and Selective Catalytic Reduction (SCR)/Adblue.

Being backwards compatible with previous API Heavy Duty Diesel classifications such as API CJ-4, CI-4 and CH-4, TOP DOG® Indestructible 15W-40 meets the requirements of most modern and older style heavy duty diesel engines from the world’s leading engine manufacturers. TOP DOG® Indestructible 15W-40 can be used in stationary engines, earthmoving and road transport applications as well as light commercial diesel vehicles requiring a 15W-40 heavy duty diesel engine oil.
