Smart product selection

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.

01
Engine & OEM requirementShare engine make, model, year and the required API or OEM specification.
02
Viscosity & climateConfirm the SAE grade permitted by the engine manual and local temperature range.
03
Operation & intervalDescribe route, load, idle time, fuel quality and the current oil-change practice.
04
Packaging & quantityState bucket or drum preference, order quantity, destination and delivery schedule.
Wear shield Oil-film support around loaded engine parts.
Cleanliness Soot, sludge and deposit management.
Viscosity Stable flow and film strength in service.
Heat control Resistance to oxidation and thermal stress.
Four-layer protection concept

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.

Selection roadmap

Choose the product in three practical steps.

Correct product selection starts with the engine—not the label colour or the longest advertised distance.

01

Confirm the requirement

Check the engine manual for API category, OEM approval, aftertreatment compatibility and permitted viscosity grades.

02

Match the operating profile

Consider climate, engine load, fuel quality, idle time, dust, route, sump capacity and filtration.

03

Validate the interval

Use the OEM schedule first. Extend only with technical approval and used-oil analysis.

Quick comparison

Seven product categories at a glance.

This matrix is a selection starting point. Open the individual product page and confirm the final TDS before ordering.
