Frequently Asked Questions (FAQ): 

Q: How often should it be added, and does it work in both direct injection and older
A: Add one dose per 5,000km. Pour into the tank before filling. Note: new diesel car registrations have been banned in Singapore from January 2025, so this product applies to owners of pre-2025 diesel passenger cars still in service, and to diesel commercial vehicle operators (vans, lorries, light trucks) where diesel engines remain in active use. Compatible with all common-rail and older injection systems; a 5,000km treatment cycle suits Singapore's stop-start urban driving.
Q: What does it clean?
A: Removes deposits from injectors and combustion chambers, improving atomisation for better performance and reduced emissions.
Q: What symptoms indicate a diesel injection system needs cleaning treatment?
A: The ONLY diesel-specific fuel additive in the SONAX range, with common-rail system compatibility for modern diesel vehicles.
Q: Is it suitable for common-rail systems?
A: Yes, particularly suited for modern common-rail diesel injection systems.
Q: How often should it be used?
A: Periodically; every 10,000km or annually as preventive maintenance, or when fuel system performance has degraded.
