Top Dog for heavy duty diesels


To­day’s heavy duty diesel en­gines are ex­pen­sive, more tech­ni­cally ad­vanced than ever be­fore, with ever-in­creas­ing oil drain in­ter­vals. A cus­tomers fleet is of­ten the back­bone of their busi­ness, with re­li­a­bil­ity and com­po­nent life mean­ing ev­ery­thing. Gulf West­ern Top Dog In­de­struc­tible has been for­mu­lated us­ing Gulf West­ern’s in­de­struc­tible ad­di­tive tech­nol­ogy, which the com­pany says makes en­gines stay cleaner, use less fuel, and last longer. Top Dog In­de­struc­tible15W- 40 meets the ma­jor­ity of mod­ern en­gine man­u­fac­tur­ers’ spec­i­fi­ca­tions. It is for­mu­lated to meet API CK- 4, which is the lat­est heavy duty diesel en­gine oil clas­si­fi­ca­tion re­leased in Jan­uary 2017 by the Amer­i­can Petroleum In­sti­tute. It meets the spec­i­fi­ca­tions of mod­ern and older en­gine man­u­fac­tur­ers and OEMs, and is back­ward com­pat­i­ble with API CJ- 4 and CI- 4 en­gine oil spec­i­fi­ca­tions. It is suit­able for heavy duty diesel en­gines fit ted with EGR ( ex­haust gas re­cir­cu­la­tion) sys­tems and those fit ted with DPFs ( Diesel Par­tic­u­late Fil­ters). Be­ing back­ward com­pat­i­ble with API spec­i­fi­ca­tions, it is an ideal mixed fleet / uni­ver­sal en­gine oil.
