DRYDENE DIESELALL® SYN 5W-40 CK-4 is recommended for use on current specification on- road equipment employing low emissions technology including EGR (Exhaust Gas Recirculation), SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filtration).

• Engineered to withstand the rigors of extreme service requirements over a wide temperature range.
• Mobile and stationary off-road equipment in mixed fleet operations.
• Current on-highway vehicles operating at both high and low speeds.
• Suitable for us in place of both mineral and synthetic 15W-40 CK-4 and CJ-4 fluids where severe low temperature applications may occur.

DRYDENE DIESELALL® SYN 5W-40 CK-4 meets or exceeds the latest API and ACEA requirements for diesel engine application along with most current OEM specifications.

DRYDENE DIESELALL® SYN 5W-40 CK-4 provides unsurpassed protection and fuel savings through its superior additive and synthetic base oil chemistry.

• Provides excellent oxidation stability which reduces the build up of sludge in low temperatures and harmful high-temperature deposits
• Helps reduce scuffing and varnishing in cylinder bores and other critical engine components.
• Advanced protection against oxidation, acid formation and viscosity breakdown due to high- temperature applications.
• Easier start up in low temperature environments which help reduce engine wear.
• Helps reduce operating costs with extended drain capabilities.
• Low-ash formulation helps control fouling of exhaust after-treatment devices, extending useful life while lowering long-term operating costs.
