Valvoline’s Premium Blue Engine Oil is designed to provide advanced lubricant performance in modern, emissions treatment equipped diesel engines, including all types of Exhaust Gas Recirculation (EGR) and Diesel Particulate Filters (DPF). When used in conjunction with Ultra-Low Diesel Sulfur fuel, this product technology offers a long-life, extended drain capable*, balanced formulation which helps maximize engine durability as well as after-treatment cleanliness.
The Premium Blue Advantage:

  • Unique dispersive polymer technology (DPT),with premium Group II baseoil, provides advanced soot control, and cold start protection.
  • Valvetrain wear protection and reduced oil filter restriction at high soot levels.
  • High temperature deposit control, including single and two-piece pistons, and ring/liner wear protection.
  • Higher TBN level and TBN retention for long-life performance, while meeting all chemical limits.
  • Endorsed and recommended by Cummins for use in Dodge Ram Turbo Diesels

Valvoline’s Premium Blue Engine Oil is endorsed by Cummins Engine Company and has been tested extensively by Cummins in stationary and on-road EGR engines, including those equipped with DPFs. It is approved against the CES 20081 specification.


How it Works

Premium Blue contains DPT — Dispersive Polymer Technology — a proprietary combination of additives that protects against soot-related valve train wear and reduces piston deposits, ring wear, liner polishing, and filter plugging.
While providing extended protection from thermal degradation and corrosion due to higher temperatures and acids from cooled Exhaust Gas Recirculation (EGR), DPT keeps soot particles in suspension so that the oil maintains optimum flow characteristics in cold weather and at operating temperatures.


Product SpecsValvoline’s Premium Blue Engine Oil is endorsed by Cummins Engine Company and has been tested extensively by Cummins in stationary and on-road EGR engines, including those equipped with DPFs. It is approved against the CES 20081 specification. It will also be approved against Mack EO-O Premium Plus 2007, Volvo VDS-4, and DDC Power Guard 93K218 specifications. It exceeds the lubrication requirements for Caterpillar, Detroit Diesel, Navistar, other heavy duty diesel engines, including engine performance requirements of Caterpillar ECF-3 and the Global DHD-1 Specification. The product meets API CJ-4, API CI-4 Plus, API CI-4, API CH-4,CG-4, CF-4, CF / SM, the performance requirements of ACEA E3-96, E5-02, E7-04 and the engine requirements of DB 228.3 ,MTU Type 2/Type 1, DDC 2000/4000 Series Type2/Type 1, MAN 3275, MAN 271. It provides excellent performance in “mixed fleet” gasoline engines, pickup and delivery, city fleet, long haul over-the-road, and off-highway applications.


I would have to recommend this non-synthetic base engine oil from valvoline(as the Valvoline premium blue extreme fully synthetic engine oil is not yet available here in the philippines). As this is the only locally available diesel engine oil that meets the latest Api CJ-4 to my personal knowledge, this would be the best rating to date available locally.

an sae 15w-40 is best suited for our country as we our engines could experience upto 40 degrees of heat but not less than 15 degrees of coldness.
