The reviewer found it especially useful for naturally aspirated and turbocharged fourstroke diesel engines as well as gasoline engines that call for API CJ4 or SM 10W30. The single biggest reason to buy is its ISOSYN Technology blend, which combines premium base oils and high performance additives to extend service life and reduce operating cost while maintaining strong piston deposit control and turbocharger protection.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISOSYN Technology:\u003c\/strong\u003e A blend of premium base oils and additives that helps provide extended service protection and improved fuel economy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxidation performance:\u003c\/strong\u003e Superb oxidation control contributes to high performance piston deposit control and reliable turbocharger protection under sustained load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetergent and dispersant chemistry:\u003c\/strong\u003e High performing additives keep engine components cleaner, reducing deposits on cylinders, pistons and rings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoot dispersancy and wear control:\u003c\/strong\u003e Exceptional soot management helps protect valve train components and minimize wear for longer engine life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixed fleet suitability:\u003c\/strong\u003e Formulated for both diesel and gasoline fourstroke engines where API CJ4 or SM and SAE 10W30 are specified, simplifying service for mixed fleets.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eDelo 400 XLE Synblend SAE 10W30 is best for professional operators and owneroperators running heavy duty diesel trucks, construction equipment, agricultural machines, or mixedfleet garages that need one oil to cover both diesel and gasoline applications meeting API CJ4 or SM.
