Semi-Syn 5W/30 SN GF-5 stands as the ultimate engine lubricant, delivering paramount engine protection and fuel efficiency for both modern and older petrol and compact diesel engines. It proudly complies with the rigorous API SN Plus and ILSAC GF-5 Resource Conserving standards.

This semi-synthetic formulation of Semi-Syn 5W/30 SN GF-5 incorporates carefully selected additives designed to confer exceptional resistance to oxidation. This quality is vital in tackling the elevated operating temperatures inside the engine, effectively reducing engine deposits and fortifying protection for critical components like pistons and turbochargers.

Semi-Syn 5W/30 SN GF-5 caters to a wide range of petrol and four-stroke engines, capably handling both extreme and diverse operating conditions. Whether you’re navigating high-temperature motorway journeys or enduring stop-and-go driving in frigid weather, this oil rises to the challenge.

A distinguishing feature of this oil is its heightened level of dispersants and detergents, ensuring rigorous control over sludge formation under all service conditions. Moreover, it incorporates friction modifiers that adeptly address internal engine friction, contributing to enhanced fuel economy.

Furthermore, Semi-Syn 5W/30 SN GF-5 utilizes fewer components known to expedite catalyst degradation, aligning with the stringent emissions standards of today while promoting extended durability of emissions systems. In essence, it excels in engine protection, fuel efficiency, and emissions control, making it a compelling choice for discerning drivers.

Always consult your vehicle owner’s manual for the manufacturer’s recommendations.


Semi-Synthetic Base Oils: Crafted from a blend of high-quality synthetic and mineral base oils, this formulation extends the lifespan of the lubricant while delivering exceptional cold-start protection.

Low-Speed Pre-Ignition (LSPI) Mitigation: Meeting the API SN Plus performance level, it is engineered to specifically combat Low-Speed Pre-Ignition (LSPI) and mitigate timing chain wear in small turbocharged petrol engines.

Oxidation and Corrosion Resistance: Exceeding the API SN Plus standards, this oil demonstrates exceptional resistance to oxidation, as evidenced by its performance in the TEOST MHT Deposit Formation test. It also excels in corrosion resistance, surpassing requirements in the Sequence VIII Bearing Weight Loss test and the Sequence VG Engine Sludge and Oil Screen Clogging test.

Superior Cam Wear Protection: It goes above and beyond the API SN Plus Sequence IVA Average Cam Wear Limit by a significant margin, promoting longer engine life with cam wear results of less than 20μm (compared to the API SN limit of maximum 90μm cam wear).

Effective Emission Control: This oil complies with stringent modern emissions standards, ensuring extended durability of emissions systems.

Catalytic Converter Preservation: Adhering to the API SN Plus Resource Conserving performance level, it regulates the percentage of retained phosphorus in the engine oil using the Sequence IIIGB test. This control of phosphorus leaching mitigates catalytic converter poisoning and exhaust system degradation.

Enhanced Fuel Efficiency: Meeting the ILSAC GF5 and API SN Plus Resource Conserving performance requirements, this oil leverages advanced technology to reduce internal friction, resulting in improved fuel economy and reduced maintenance costs. Performance in the Sequence VID test for Improved Fuel Efficiency, along with results from the Sequence IIIG Oil Thickening and Cam Lifter Wear test, validates these claims.
