Koyoto CK-4/SN series are advanced performance low-SAPS fully synthetic diesel engine oils formulated with severely refined base stocks and sophisticated technology additives to provide outstanding engine performance in the latest emission designs, including those with after treatment systems with Diesel Particulate Filters (DPF), Selective Catalytic Reduction (SCR) and Diesel Oxidation Catalyst (DOC). It may be used in both new and old diesel engines for On & Off highway applications, due to it’s backward compatibility down to CJ-4 specifications and may also be used in gasoline engines requiring the API SN specification. They are specifically formulated to deliver excellent wear and engine protection, extended drain capability with excellent TBN retention, outstanding high temperature performance and engine cleanliness.

• Excellent oil consumption control, due to very oil low volatility and less oil top-up during operation.
• Outstanding oxidation & thermal stability reduces sludge deposits and keeps the engine cleaner.
• Excellent engine protection by providing outstanding protection against corrosive & abrasive wear.
• Improved shear stability maintains viscosity in-grade under severe, high-temperature service conditions.
• Excellent low-temperature pumpability ensures smooth cold starting and improved fuel economy.
• Excellent TBN reserves provide improved acid neutralization and corrosion protection, which helps in
extending oil drain interval in both new & old engines using either low (500 ppm) or ultra-low (15 ppm)
sulfur diesel fuel.
