Its special formulation allows Alfatech 10W-30 to exceed the highest international specifications for heavy duty diesel engines, i.e.: API CH4 and ACEA E5. Therefore,this lubricant warrants high operating performance for the new-generation engines which must also meet the stringent limits imposed by international standards in terms of emissions. The fulfilment of these standards is obtained through effective control of the thickening caused by the particular combustion features of low-emission engines,especially the formation of soot. Remarkable protection is also offered against the wear caused by the soot itself. >> Compliance with API CH4 and ACEA E5 specifications allows Alfatech 10W-30 to contribute to the need to lengthen the interval between changes, thereby reducing machine down times. Indeed, Alfatech 10W-30 offers prolonged and constant protection of the engine against the wear caused by high operating loads.
