Flashlube Winter Fuel Formula — Cold Diesel Flow Improver
Flashlube Winter Fuel Formula is a highly effective cold diesel fuel flow improver that increases the effective flow range of diesel and biodiesel fuels at low temperatures down to -15°C.
- Prevents diesel wax crystallisation and fuel gelling (clouding) that can plug fuel lines and filters
- Improves cold diesel flow for easier cold weather starting
- Contains a highly concentrated anti-gelling additive formulated for maximum cold temperature protection
- Controls moisture formation and fights fuel line freeze
- Reduces misfiring caused by cold fuel flow restriction
- Improves thermal stability of diesel fuel
- Suitable for biodiesel fuels and low sulphur diesel
- Treat rate: 2mL per 1 litre of diesel fuel (double on first usage for maximum coverage)
- Extreme conditions treat rate: 200mL per 50 litres
- 500ml bottle — treats up to 250 litres at standard rate
Directions: 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 to the tank at the time of refuelling — the turbulence of filling will adequately mix the additive through the fuel. Can also be added to storage tanks before refilling. Important: Add only when the 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.
