HIGHTEC DPF Clean and Protect is a specialised fuel additive developed to keep the diesel particulate filter working as it should. It lowers soot formation and exhaust emissions, supports the filter's regeneration process and helps maintain engine performance. Used regularly, it reduces the risk of DPF clogging and the costly servicing that follows.

Purpose and specifications

This additive is intended for all diesel engines equipped with a diesel particulate filter, including vehicles that mainly cover short distances where passive regeneration is difficult. As a universal maintenance product it carries no vehicle-specific OEM approvals and suits any DPF-equipped diesel. It reduces soot and emissions, improves engine performance and actively supports efficient DPF regeneration.

• 0.250L container, sufficient to treat 40 to 60 liters of diesel per dose
• Works while driving and lowers the soot load entering the particulate filter
• Helps keep the DPF clean and supports the burn-off cycle that protects the filter
• Maintains engine performance and efficiency by easing exhaust backpressure

When to use / change?

Use this additive as ongoing preventive maintenance, ideally every 4,000 km as recommended on the pack, and especially if your driving involves frequent short trips. Add it to the fuel before refueling and let it work during normal driving. It is stable across the engine's operating temperature range and through cold and warm seasons alike. Shelf life is approximately 5 years when the container is kept sealed in a cool, dry place.

Frequently asked questions

How often should I add it?
For best protection add one treatment roughly every 4,000 km, before refueling.

Will it help if my DPF light keeps coming on?
Regular use helps support regeneration and reduce soot, which can ease frequent regeneration cycles, though a fully blocked filter may still need professional service.

Is it suitable for short-trip city driving?
Yes, it is especially beneficial for short-distance use where the filter struggles to regenerate on its own.

Suitable for: all diesel vehicles fitted with a diesel particulate filter (DPF). Always verify the exact approval against your vehicle's owner manual before use.
