Every product below follows one unified premium layout. Product artwork stays centred, each category keeps its own colour identity, and the information hierarchy helps buyers compare application, protection focus and service position more quickly.
API CFOlder off-road and compatible diesel engines
A legacy-category lubricant for older off-road, indirect-injection and compatible diesel engines where API CF is specifically required.
API CF-4Naturally aspirated and turbocharged diesel
Designed for compatible high-speed four-stroke, naturally aspirated or turbocharged diesel engines that specify the older CF-4 category.
API CH-4Heavy-load and turbocharged applications
Severe-duty protection for compatible high-speed four-stroke diesel engines, including heavy-load and turbocharged applications.
API CI-4Up to 40,000 km*
EGR-focused heavy-duty protection with a marketed service position of up to 40,000 km under approved operating conditions.
One CK-4 category. Two fleet-service options.
CK-4 60,000 km and CK-4 100,000 km are presented together as one product category. Select the service option according to OEM limits, duty cycle, filtration, fuel quality, maintenance control and used-oil analysis.
API CK-460,000 km* / 100,000 km*
Advanced oxidation, shear, aeration, soot and wear control for compatible modern heavy-duty engines, with two condition-dependent service positions under one CK-4 category.
Specialized support for CNG and LNG engines.
Gas-engine oils must be selected around OEM-specific deposit, oxidation, valve-train and ash requirements—not simply treated as ordinary diesel lubricants.
Natural Gas15W-40
Dedicated multigrade lubrication for compatible mobile and stationary natural-gas engines.
Natural Gas10W-40 · 60,000 km*
Product designation supplied for a long-distance gas-engine series. Final TDS confirmation is required.
Choose by engine requirement—not only by label colour or drain-distance claim.
The most suitable lubricant depends on the engine specification, permitted viscosity grade, emission-system compatibility, operating severity and maintenance controls. Use the four checkpoints below before requesting a quotation.
Lubrication that works around the whole engine.
A commercial engine oil must do more than reduce friction. It must manage contamination, retain viscosity, protect hot components and support the engine’s emissions-era requirements.
Wear and component protection
Supports bearings, rings, liners, cam systems, valve trains and turbocharger components.
Soot and deposit control
Helps keep contaminants suspended and limits harmful deposits in critical engine zones.
Service-interval control
Long-drain programs should be managed through OEM limits, maintenance discipline and oil analysis.
Choose the product in three practical steps.
Correct product selection starts with the engine—not the label colour or the longest advertised distance.
Confirm the requirement
Check the engine manual for API category, OEM approval, aftertreatment compatibility and permitted viscosity grades.
Match the operating profile
Consider climate, engine load, fuel quality, idle time, dust, route, sump capacity and filtration.
Validate the interval
Use the OEM schedule first. Extend only with technical approval and used-oil analysis.
