Maintaining your Cat HEUI system

The HEUI system relies on clean engine oil to function properly. Contaminated oil can lead to premature injector failure. Here are some key points to keep in mind to make sure you are maximising your vehicle output:

Strict Maintenance Schedule

Follow the manufacturer’s recommended maintenance intervals for oil changes and filter replacements.
High-Quality Oil & Filters

Use high-quality diesel fuel and oil filters designed for HEUI systems.
Clean Engine Oil

HEUI engine oil works harder than standard engine oil. Choose an oil rated for the pressures within the HEUI system, typically between 500 psi and 3,600 psi.
Regular Injector Maintenance

Regular planned injector maintenance prevents costly breakdown repairs and ensures your vehicle and output is constantly maximised.
