Liqui Moly DPF Cleaner & Regenerator Twin Pack 2×250 ml — Concentrated Diesel Particulate Filter Treatment

Liqui Moly Diesel Particulate Filter Protector is a twin-pack of 250 ml DPF cleaner and regenerator designed to help remove soot deposits and support cleaner filter operation in diesel engines.

This two-bottle set (2 x 250 ml) from Liqui Moly contains a concentrated DPF cleaner and regenerator (product code 7180) formulated for periodic maintenance of diesel particulate filters. It is intended to be introduced into the fuel or dosing system according to manufacturer guidance to assist soot burn-off during regeneration cycles and reduce the risk of premature filter blocking. The formula is compatible with many modern diesel systems but follow vehicle manufacturer and local regulations before use.

How does this Liqui Moly product help my diesel vehicle?

The cleaner is formulated to support the removal of accumulated soot and ash particles that can restrict exhaust flow. By assisting in the regeneration process, it helps maintain exhaust backpressure at lower levels and can extend service intervals when used as part of a regular maintenance routine.

• Supports DPF regeneration by aiding soot combustion.
• Helps reduce soot-related exhaust backpressure.
• Suitable for periodic treatment as specified by vehicle guidelines.
• Concentrated 250 ml dosing for targeted use per treatment.

When and how should I use the 2 x 250 ml bottles?

Use bottles according to the instructions on the product label or the vehicle manufacturer’s recommendations. Typically, one bottle is added to the diesel tank or dosing port before a long drive that allows the engine to reach sustained operating temperature, which helps the cleaner be effective during regeneration.

• Follow the application steps printed on Liqui Moly 7180 packaging.
• Best applied before extended motorway or highway driving.
• Allow the engine to complete at least one full regeneration cycle after treatment.
• Keep within recommended treatment intervals; this pack contains two treatments.

Is this product compatible with my DPF-equipped diesel car?

Liqui Moly designs its DPF cleaners for many modern diesel systems, but compatibility depends on vehicle make, model and emission system design. Check the vehicle handbook or contact a qualified technician to confirm compatibility and whether this type of additive is appropriate for your engine management and emissions controls.

• Compatible with many common diesel engines and DPF systems.
• Not all vehicles require additives—verify with manufacturer guidance.
• Avoid use if vehicle instructions expressly prohibit fuel additives.
• When in doubt, consult a dealer or experienced service provider.

What practical benefits can I expect after using the cleaner?

When used correctly, the product can help maintain smoother exhaust flow and reduce the frequency of forced DPF cleaning or replacement. Results vary with driving conditions, filter condition and how regularly maintenance treatments are applied.

• Potentially fewer forced regenerations or service interventions.
• Cleaner exhaust pathways support engine efficiency.
• May prolong the effective service life of the DPF when combined with proper driving habits.
• Two 250 ml bottles provide multiple maintenance treatments.

Who is this for: This Liqui Moly 2 x 250 ml DPF Cleaner Regenerator pack is aimed at owners of diesel vehicles equipped with particulate filters who perform regular maintenance and who undertake highway driving that allows effective regenerations. It suits DIY enthusiasts and professional workshops that follow manufacturer guidance and want a reliable, concentrated treatment to support DPF performance. Avoid use on vehicles where additives are contraindicated or without confirming compatibility with your vehicle’s emission system.
