Automotive and heavy-duty engine lubrication
Engine oils matched to viscosity, engine requirements and duty cycle.
Explore LubeMax engine oils for passenger vehicles, commercial fleets, workshops and heavy-duty operations, supported by responsible specification language and current technical documents.

Select with evidence
Viscosity is important—but it is not the whole specification.
An engine oil must be evaluated against the engine manufacturer’s required viscosity and performance level, the engine design, fuel, age, operating temperature, duty cycle and maintenance practice. A familiar viscosity grade alone does not establish suitability.
| Selection factor | What to confirm | Typical risk if ignored | Where to verify |
|---|---|---|---|
| Viscosity grade | Required SAE grade and expected start-up and operating temperatures | Poor cold flow, excessive drag or inadequate operating-film strength | Owner’s manual and current LubeMax TDS |
| Performance requirement | Equivalent API, OEM or industry performance reference | Oil may not address the required engine technology or service level | Owner’s manual, service bulletin and TDS |
| Engine and fuel | Petrol or diesel, emissions system, turbocharging and fuel quality | Additive and after-treatment compatibility may be unsuitable | Equipment documentation |
| Duty cycle | Highway, stop-start, idling, short trips, heavy load, dust or heat | Severe service can require different maintenance intervals | Fleet maintenance plan |
| Oil-change practice | Approved interval, filter condition, consumption and monitoring | Extending intervals without evidence can increase wear or deposits | OEM guidance and condition data |

Build a complete engine-oil requirement.
Good selection begins with the exact engine and service environment. This reduces specification errors across mixed fleets and workshop operations.
- Confirm the engine make, model, year, fuel and emissions system.
- Record the required SAE viscosity and equivalent performance specification.
- Describe the duty cycle, load, idling, dust, heat and trip pattern.
- Review oil consumption, filter condition and current maintenance interval.
- Use the current LubeMax TDS and request technical review when requirements are uncertain.
Where selection matters
Match the lubricant to the equipment and duty.
Product choice should reflect the component, operating environment, maintenance practice and consequences of an incorrect recommendation.
Commercial transport
Control product selection across mixed engines, routes, loads, fuel conditions and maintenance intervals.
Passenger vehicles
Match the exact engine requirement rather than selecting by vehicle age or viscosity alone.
Heavy equipment
Account for dust, heat, heavy load, idling and the engine manufacturer’s severe-service guidance.
Technical selling
Use discovery questions and current documents to recommend responsibly and reduce misapplication.
Responsible specifications
Equivalent performance is not formal approval.
LubeMax products do not currently carry API approval, licensing or certification. Any API, OEM or industry reference describes equivalent performance to the stated requirement unless the current product TDS expressly identifies a formal approval.
Technical documents
Use current product information.
Request the exact document for the product and grade being evaluated. Never substitute one product’s data sheet for another product with a similar name.
Technical Data Sheet
Applications, benefits, equivalent performance references and typical characteristics.
Safety Data Sheet
Safe handling, storage, exposure control and emergency information.
Product Selection
Support for equipment requirements, mixed fleets, unusual duty or changeover questions.
Frequently asked questions
Engine oil selection questions.
Is the viscosity grade enough to select an engine oil?
No. Confirm the required performance level, engine design, fuel, emissions system, duty cycle and operating temperature.
What do CH-4 and CI-4 mean on LubeMax product names?
They identify equivalent API performance references. They do not mean that the products are API approved, licensed or certified.
Can a 20W-50 oil replace a 15W-40 oil?
Not by assumption. Use the viscosity and performance requirement stated for the engine and operating conditions.
Can I extend the oil-drain interval?
Only when supported by the equipment manufacturer’s guidance, operating conditions, maintenance controls and appropriate condition evidence.
What information should a fleet provide?
Provide engine models, fuel, current oil, required viscosity and specification, duty cycle, drain practice and any operating concern.
Are LubeMax engine oils API approved?
No. LubeMax products do not currently carry API approval, licensing or certification; references describe equivalent performance.
Where can I obtain the current TDS and SDS?
Request the exact product and grade through the LubeMax Technical Resources centre.
Do LubeMax engine oils have SON approval?
All LubeMax products have SON approvals except where the current TDS clearly states “Pending approval.”
