Product Overview

The K10 represents the pinnacle of ROCKEFELLER’s diesel engine oil technology — the ultimate expression of lubrication engineering for the most demanding commercial diesel applications in the world. Formulated with PAO (polyalphaolefin) fully-synthetic base oil — the gold standard of synthetic base stocks — combined with proprietary original compound additives, the K10 delivers a level of performance that meets and exceeds the requirements of the latest API CK-4 specification, the highest current API diesel engine oil category.

API CK-4 was introduced in December 2016 as a replacement for CJ-4, representing a significant advancement in diesel engine oil performance requirements. CK-4 oils must demonstrate improved oxidation resistance, better shear stability, enhanced aeration control, and superior protection for engines equipped with the full suite of modern exhaust aftertreatment systems — including Exhaust Gas Recirculation (EGR), Diesel Particulate Filters (DPF), Diesel Oxidation Catalysts (DOC), Selective Catalytic Reduction (SCR), and Three-Way Catalytic (TWC) devices. The K10 is engineered to protect all of these systems while simultaneously delivering maximum engine protection and extended drain interval capability.

The PAO base oil foundation provides inherent advantages over conventional mineral and even Group III synthetic base oils: superior thermal stability that resists breakdown at extreme temperatures, excellent low-temperature fluidity for reliable cold starts in harsh winter conditions, naturally low volatility that minimizes oil consumption and exhaust emissions, and outstanding viscosity-temperature stability that maintains consistent protection across the full operating temperature range.

The K10 is manufactured to the highest international standards with a five-year shelf life and is available in both 4-liter tins and 18-liter buckets.

Key Functional Features and Performance Benefits

Primary Features (PAO-Based Formulation)

★ PAO Polyalphaolefin Base Oil with Original Compound Additives — Stable Viscosity, Strong Power, Energy Saving, and Environmental Protection:
The K10’s PAO base oil foundation provides an inherently superior molecular structure compared to conventional mineral or hydro-processed base oils. PAO molecules are uniform in size and shape, with no impurities, wax content, or reactive double bonds. This molecular perfection translates directly into:

• Stable viscosity change: The oil maintains its designed viscosity grade throughout the entire drain interval, resisting the viscosity increase caused by oxidation and soot loading, and the viscosity decrease caused by mechanical shear. This means the engine receives consistent, predictable lubrication from the first kilometer to the last — whether that interval is 30,000 km, 50,000 km, or more.
• Strong power delivery: By maintaining optimal oil viscosity and minimizing internal friction, the K10 reduces parasitic power losses within the engine. More of the fuel’s energy reaches the wheels, translating into measurably better power output, improved throttle response, and enhanced drivability — particularly noticeable under heavy load and hill-climbing conditions.
• Energy saving: Reduced internal friction means less fuel is required to produce the same power output. For commercial fleet operators, even a 1-2% reduction in fuel consumption translates into significant cost savings over tens of thousands of operating hours.
• Environmental protection: The PAO-based formulation produces lower exhaust emissions, generates fewer volatile organic compounds, and is more resistant to the formation of harmful combustion byproducts, contributing to cleaner air and reduced environmental impact.

★ Excellent Piston Deposit Control, Lubrication, and Anti-Wear Performance — Effectively Reduce Wear, Keep Engine Clean, Extend Engine Life:
The K10’s advanced additive package delivers exceptional control of piston deposits — the carbon, varnish, and lacquer that accumulate on piston crowns, ring lands, ring grooves, and undercrown surfaces. Uncontrolled piston deposits cause ring sticking (which leads to blow-by, increased oil consumption, and power loss), increased piston crown temperatures (which can lead to pre-ignition and piston damage), and reduced cooling efficiency. The K10’s deposit control system keeps piston surfaces exceptionally clean, ensuring free ring movement, optimal compression, and maximum thermal efficiency throughout the extended drain intervals that modern commercial operations demand.

★ Excellent Low-Temperature Flow Performance and Viscosity-Temperature Characteristics — Smooth Cold Starts and Stable Hot Oil Pressure:
PAO base oils have inherently excellent low-temperature properties due to their lack of wax content and uniform molecular structure. The K10 flows freely at extremely low temperatures, ensuring rapid oil delivery to all engine components during cold starts — the period when the majority of engine wear occurs. At the other extreme, during sustained high-temperature, high-load operation (highway cruising, mountain passes, heavy towing), the K10’s viscosity-temperature stability ensures the oil maintains sufficient film thickness and oil pressure to protect all bearing surfaces and critical components.

Advanced Performance Features (Heavy-Duty Application)

★ Super Abrasion Resistance — Effective Protection Under Various Extreme Working Conditions:
The K10’s super anti-wear additive system provides an additional level of protection beyond standard anti-wear packages. This advanced system creates multiple layers of protective films on metal surfaces — a primary chemical tribofilm at the molecular level plus a secondary physical film — that together resist wear under the most extreme conditions including: high-load towing, steep-grade operation, extreme ambient temperatures (both hot and cold), dusty and dirty environments, and stop-and-go urban delivery operation. The result is measurably reduced wear on all critical engine components, directly extending the interval between major engine overhauls.

★ Excellent Shear Resistance — Super Long-Lasting Stable Oil Pressure:
Viscosity modifiers (VII) in multi-grade diesel oils can be broken down by the intense mechanical shearing forces within the engine — particularly in high-pressure fuel injection pumps, gear trains, and between piston rings and cylinder walls. When VII polymers are sheared, the oil’s viscosity drops permanently, reducing its load-carrying capacity and potentially allowing metal-to-metal contact. The K10’s PAO base oil has inherently high shear stability (because PAO molecules are already small and uniform, they resist further fragmentation), and the carefully selected VII polymers are of the highest shear-stable grade available. The result is super long-lasting stable oil pressure that remains consistent throughout the entire drain interval, providing reliable protection and consistent engine behavior over extended service periods.

★ Effective Soot and Deposit Dispersion — Control Engine Oil Sludge and Piston Ring Deposits:
Diesel engines produce significant quantities of soot (carbon particles) as a normal byproduct of combustion. This soot enters the oil through blow-by gases and, if not properly managed, can cause dramatic increases in oil viscosity (oil thickening), accelerated wear (soot acts as an abrasive), and blockage of oil passages and filters. The K10 incorporates an advanced soot dispersancy system that:

• Keeps individual soot particles separated and suspended in the oil, preventing agglomeration into larger, more harmful clusters
• Prevents soot-related oil thickening, maintaining designed viscosity even at high soot loading levels
• Controls piston ring deposits, ensuring free ring movement and maintaining compression
• Prevents sludge formation in the crankcase, oil galleries, and on valve train components

★ Excellent Rubber Compatibility — Effectively Protect Sealing Materials and Prevent Leakage:
Modern diesel engines use a variety of elastomeric sealing materials (Viton, silicone, nitrile, polyacrylate, etc.) for crankshaft seals, valve cover gaskets, oil pan gaskets, and various O-rings and grommets. Incompatible lubricants can cause these seals to swell, shrink, harden, or crack, leading to oil leaks that result in environmental contamination, fire hazards, and engine damage from oil starvation. The K10 is specifically formulated and tested for excellent compatibility with all common seal materials, maintaining seal flexibility, dimensions, and integrity throughout the oil’s service life. This is particularly critical for the K10 because its extended drain capability means seals are exposed to the oil for longer periods.

★ Excellent Acid Neutralization and Anti-Oxidation Ability — Ensure Long Oil Change Period:
The K10 features a robust alkaline reserve (high Total Base Number — TBN) that effectively neutralizes the acidic combustion byproducts that inevitably enter the oil, particularly the sulfuric acid formed from sulfur in diesel fuel. This acid neutralization capability, combined with the PAO base oil’s inherent oxidation resistance and the advanced anti-oxidant additive system, ensures the K10 can safely deliver the extended drain intervals demanded by modern commercial operations — typically 50,000–80,000+ km for on-highway applications and 500–1,000+ hours for off-highway applications, depending on operating conditions and fuel quality.

★ Efficient Protection of EGR, DPF, DOC, SCR, and TWC Aftertreatment Systems:
The K10 is formulated with carefully controlled levels of sulfated ash, phosphorus, and sulfur (SAPS) to protect the full suite of modern diesel exhaust aftertreatment systems:

• EGR (Exhaust Gas Recirculation): Protected against deposit formation in EGR coolers and valves, maintaining EGR system efficiency and preventing the costly EGR-related failures that plague commercial fleets
• DPF (Diesel Particulate Filter): Low ash formulation minimizes the accumulation of non-combustible ash in the DPF, extending regeneration intervals and preventing premature DPF plugging
• DOC (Diesel Oxidation Catalyst): Low phosphorus and sulfur levels prevent poisoning of the DOC catalyst, maintaining its ability to oxidize CO, HC, and the soluble organic fraction (SOF) of diesel particulate matter
• SCR (Selective Catalytic Reduction): Compatible with urea-based SCR systems (AdBlue/DEF), ensuring no interference with the NOx reduction process
• TWC (Three-Way Catalyst): Effective protection of three-way catalytic devices where fitted
