Würth Dieselcure

Würth Dieselcure is a comprehensive diesel fuel treatment engineered to clean, protect, and restore fuel system performance. The multi-function formulation removes existing deposits, prevents new contamination, neutralises corrosion-causing acids, and eliminates water whilst improving fuel lubricity and injection precision.

Key Features

  • Increases Diesel Lubricity — The formulation enhances fuel's natural lubricating properties, reducing wear on fuel pumps and injection components and extending component service life.
  • Improves Atomisation — Cleaner fuel with optimised properties atomises more effectively, creating finer spray patterns that improve combustion efficiency and power delivery.
  • Loosens and Removes Deposits — The cleaning action dissolves and suspends resinified deposits that accumulate throughout the fuel system from the tank through to the combustion chamber.
  • Ensures Precise Injection — By removing deposits that restrict or distort injector spray patterns, Dieselcure restores the precise fuel delivery that modern diesel engines require.
  • Reduces Fuel Consumption — Improved atomisation and precise injection mean more complete combustion and less wasted fuel, reducing consumption and improving economy.
  • Prevents New Deposits — Beyond removing existing deposits, the formulation includes anti-oxidant and anti-resin compounds that prevent new deposit formation.
  • Binds and Neutralises Acid Condensation — Diesel tanks accumulate acidic condensation through temperature cycling. The treatment chemically neutralises these acids, preventing corrosion formation.
  • Protects Against Corrosion — The protective layer created by the treatment inhibits rust and corrosion in fuel system components.
  • Removes Water from Fuel Systems — The formulation safely removes water contamination that accumulates in fuel tanks without damaging engine components or water seals.
  • Prevents Bacterial Growth — By removing water that bacteria thrive in, the treatment prevents microbial contamination that degrades fuel quality.
  • Increases Fuel Storage Stability — Treated diesel resists degradation during storage, maintaining fuel quality over extended periods.
  • Suitable for All Diesel Types — The formulation works with conventional diesel, ultra-low sulphur diesel, and biodiesel blends.
  • Approved by Major Manufacturers — Approved by MTU Friedrichshafen GmbH and Detroit Diesel Corporation, confirming compatibility with professional and heavy-duty applications.

Description

Diesel Fuel System Complexity and Multi-Function Treatment

Diesel fuel systems are more sophisticated than petrol engines — they operate at higher pressures, require precise fuel delivery, and depend on fuel's lubricating properties to protect injection components. Over time, fuel oxidation creates deposits, condensation creates acids, and contamination accumulates. Single-function additives address one problem; Dieselcure addresses the entire ecosystem of diesel fuel challenges simultaneously.

Lubricity as Critical Engine Protection

Modern diesel fuel, particularly ultra-low-sulphur diesel (ULSD), has lower natural lubricity than older fuel formulations. This reduced lubricity accelerates wear on fuel pumps and precision injection components. Dieselcure increases lubricity through additive chemistry, protecting these expensive, wear-prone components and extending their service life.

Deposit Formation and Fuel Quality Degradation

Diesel stored or exposed to oxygen gradually oxidises, forming varnish and resin deposits. These accumulate in fuel tanks and throughout the system, particularly on injector tips where they restrict spray patterns. This deposit formation is progressive — regular treatment prevents the escalating problems that result from heavy accumulation.

Acid Neutralisation as Corrosion Prevention

Water in diesel tanks becomes acidic through interaction with dissolved oxygen and fuel compounds. This acidity accelerates corrosion of steel tanks and fuel system components, eventually leading to leaks and failures. Dieselcure's acid neutralisation prevents this chemical attack before it damages components.

Water Removal Without Engine Damage

Water in fuel can damage engines — it causes corrosion, interferes with injection precision, and supports bacterial growth. Traditional water-removal methods sometimes use compounds that damage seals or components. Dieselcure's ethylene glycol base safely removes water whilst protecting all engine components.

Bacterial Prevention Through Water Elimination

Diesel sludge (often called "diesel bug") results from bacterial growth in water-contaminated fuel. By removing the water that bacteria require, Dieselcure prevents the microbial contamination that degrades fuel quality and clogs filters.

Emission Reduction Through Combustion Improvement

Improved atomisation and precise injection result in more complete combustion, reducing unburned hydrocarbons and particulate matter that contribute to emissions and environmental pollution.

Compatibility Across Diesel Types

Modern diesels include conventional fuel, ultra-low-sulphur diesel, and increasingly, biodiesel blends. Dieselcure is formulated to work with all these fuel types without incompatibility issues.

More Information

Application Instructions

Determine fuel tank capacity — Identify your vehicle's or equipment's diesel tank size to verify appropriate dosage.

Check current fuel level — Ideally, treat when the fuel tank is approximately one-quarter full. This ensures good mixing of the treatment with existing fuel.

Prepare the treatment — Locate the fuel filler opening. Ensure caps and seals are accessible.

Shake the container well — Mix Dieselcure thoroughly to ensure uniform consistency before emptying into fuel tank.

Empty contents into fuel tank — Carefully empty the entire 330 mL container into the fuel tank through the fuel filler opening.

Replace fuel filler cap — Securely close the fuel filler cap.

Drive the vehicle normally — No special driving procedure is required. Normal driving circulates the treatment through the fuel system.

Allow circulation — As you drive, the treatment circulates through the fuel system, cleaning injectors and treating the fuel.

Complete fuel tank cycle — For maximum benefit, allow at least one full fuel tank cycle before refuelling. This ensures the treatment has circulated completely through the system.

Observe improvements — Monitor fuel consumption, engine smoothness, and starting characteristics over the following days as deposits dissolve and fuel system performance improves.

Preventative use — For optimal fuel system health, repeat treatment annually or per manufacturer recommendations.

FAQs

How often should I use Dieselcure?

For preventative maintenance, use annually or at major service intervals. For vehicles experiencing rough running, high fuel consumption, or known deposit problems, treat immediately, then continue with preventative annual use.

Will Dieselcure work on biodiesel blends?

Yes, Dieselcure is specifically formulated for conventional diesel, ultra-low-sulphur diesel, and biodiesel blends. The treatment works effectively regardless of blend percentage.

Can I use this in agricultural machinery or maritime engines?

Yes, Dieselcure is approved for all diesel engines including agricultural machinery, maritime engines, and heavy-duty truck applications. Coverage is 330 mL per up to 400 litres.

How quickly will I see improvements in fuel consumption?

Fuel consumption improvements are often noticeable after the first complete fuel tank cycle (typically within a few days). Rough running or starting improvements may appear even sooner as deposits dislodge.
