More Details
Main highlights
- ✅ RESTORES ENGINE PERFORMANCE AND PREVENTS STARTING ISSUES: Designed to bring engines back to their optimal working condition by eliminating contaminants that hinder performance. It helps to restore lost power, ensuring smooth acceleration and a steady idle. Additionally, this treatment minimises engine hesitation, misfires, and irregular combustion, providing a more reliable driving experience. By eliminating injector clogging and deposit buildup, it enhances combustion efficiency, making cold starts easier and more dependable.
- ✅ POWERFUL ONE-TANK CLEANING FOR DIESEL ENGINES: Formulated to deliver a deep and effective cleaning process in just one tank, ensuring that diesel engines operate at their peak performance. Designed to target and remove stubborn deposits, this advanced formula works efficiently to clean injectors and maintain optimal fuel delivery. It also contributes to keeping the EGR valve and turbo clean, preventing blockages that could impact engine efficiency. Suitable for all types of diesel engines, including high-pressure common rail and pump injector systems, this one-tank solution ensures thorough cleansing while optimising fuel combustion and engine power.
- ✅ LUBRICATION AND PROTECTION FOR INJECTION SYSTEMS: Provides superior lubrication to critical fuel system components, reducing wear and extending the lifespan of injectors and pumps. This protective action is especially beneficial for high-pressure injection systems, such as TDI, HDI, and other advanced diesel technologies, which require precision and durability to function effectively. By forming a protective barrier, this formulation minimises friction and enhances the smooth operation of fuel delivery components, preventing premature wear and costly repairs.
- ✅ IMPROVES FUEL ECONOMY AND ENHANCES ENGINE RELIABILITY: Contributes to better fuel efficiency by ensuring a clean and well-maintained fuel system. With enhanced injector performance and optimised combustion, diesel engines operate more efficiently, reducing fuel consumption and operational costs. The increased fuel economy leads to lower emissions, making it an environmentally conscious choice. Additionally, this treatment enhances engine reliability by preventing unexpected breakdowns related to fuel system issues, offering peace of mind and long-term performance benefits for diesel vehicle owners.
- ✅ CLEANS AND PROTECTS INJECTORS FOR OPTIMAL SPRAY PATTERN: Instantly eliminates harmful carbon deposits and residues that accumulate over time in injectors, restoring them to their original efficiency. By maintaining an ideal injector spray pattern, this treatment ensures precise fuel atomisation, resulting in improved combustion, lower emissions, and better fuel economy. The enhanced spray pattern promotes smoother engine operation, reducing vibrations and noise. Continuous use helps maintain the cleanliness of injectors, ensuring consistent fuel delivery and long-term engine reliability, making it an essential solution for preserving diesel engine health.
