Flashlube Winter Fuel Formula — Cold Diesel Flow Improver
Flashlube Winter Fuel Formula is a highly effective cold diesel fuel flow improver that extends the effective flow range of diesel and biodiesel fuels at low temperatures down to -15°C.
- Inhibits and prevents wax crystal gelling (clouding) in diesel fuel at low temperatures
- Improves cold diesel fuel flow — effective protection down to -15°C
- Easier cold weather starting and reduces misfiring
- Fights fuel line freeze and controls moisture formation
- Improves thermal stability of diesel fuel
- Suitable for biodiesel and low sulphur diesel fuels
- Highly concentrated formula — treat rate 2mL per 1 litre of diesel fuel
- Double treat rate recommended on first usage for maximum lubrication coverage
- In extreme conditions: 200mL treats 50 litres (2 litres treats 500 litres)
Directions for use: For best results, treat one full tank of fuel prior to your trip to ensure maximum protection of fuel system components. Add Flashlube Winter Fuel Formula directly to new fuel at delivery — the turbulence will mix it through the fuel. Winter Fuel Formula can also be added to storage tanks before refilling; the recirculating fuel will ensure adequate dispersion. Important: Add the product when diesel fuel temperature is above the onset of clouding (approximately 0°C).

German Scientist, Wolfgang Kluenner in 1979, developed Flashlube in Melbourne Australia. Wolfgang was a CSIRO (Commonwealth Scientific and Industrial Research Organisation) Scientist and worked from Monash University. He recognised the problem of Valve Seat Recession in Gas converted vehicles and thus devoted his time to researching and inventing the solution. The answer was the Flashlube Valve Saver Kit and its specially formulated Flashlube Valve Saver Fluid.
Flashlube Pty limited was formed in 1995 to take Wolfgang's technology to the world.

Recently the fuel industry began to modify its Diesel Fuel and supply only Low Sulphur Diesel Fuel. Although environmentally beneficial, this new standard caused concern for the older Diesel vehicle industry and a solution was sought after. With thorough and lengthy research behind it, Flashlube Diesel Conditioner was introduced into the market. Its ability to lubricate (with a sulphur free formulation) like original diesel fuel, was well recognised by its 2005 Australian Automotive Aftermarket Association - Gold Award.
Flashlube's use is growing rapidly into the motor vehicle, farming, industrial, transport and motorbike markets across the world. Flashlube is currently now available in Australia, Europe, North America, South America, South East Asia and India.
Wolfgang has been noted to be proud that his invention has not only been trusted, but also appreciated by the automotive market. As we step forward, Flashlube is committed to its development and research that grows this appreciation.
Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): For products listed to suit a specific vehicle, our fitment data is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing. If you have any doubt, please message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm before you buy.
