Archer Gold Synthetic Blend SAE 10W-30 heavy-duty diesel engine oil is an API CK-4 oil, formulated using a combination of synthetic and mineral base oil. This blend of base oil provides outstanding protection against high-temperature oxidation, reducing harmful deposits.

Archer Gold Synthetic Blend SAE 10W-30 heavy-duty diesel engine oil protects and performs in all seasons. It safeguards engines under extreme heat equal to or exceeding typical multi-viscosity diesel engine oils. This oil also provides better protection in cold temperatures, especially at startup. This is a particularly important period during which an engine can be damaged if oil fails to reach the correct operating pressure and all critical lubrication areas quickly.


  • Specially formulated to meet the requirements of EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filters), and DOC (Diesel Oxidation Catalysts) equipped engines as well as enhance the performance and durability of older engines.
  • Industry-leading shear stability maintains viscosity in support of extended drain intervals.
  • Enhanced aeration control protects against air, foam, and bubbles to help maintain the integrity of the oil for proper film protection.
  • Excellent oxidation protection at higher temperatures.
  • Provides exceptional oil consumption control, which will lower oil costs due to less make-up oil during operation.
  • Formulated to provide superior soot control for protection against abrasive wear and soot-induced oil thickening.
  • Up to 30% synthetic base oil blended with hydrocracked group II base oil, refined using the most advanced techniques available.
  • Excellent cold-temperature performance.
  • Measurable improvement in fuel economy versus conventional 15W-40 engine oil.
