Most people underestimate the amount of product required for shock treatments and ongoing maintenance, so order more than you think you’ll need. Fuel Doctor does not expire or degrade so will last indefinitely in a well sealed bottle. So we generally advise ordering a selection of sizes depending on what you’re treating.

For small orders, the international shipping cost generally is more than the product itself. Please bear this in mind before requesting a quote, as finding a range of suitable shipping services for you can be a time consuming process.

We generally advise ordering a selection of sizes depending on what you’re treating.

  • 250ml are great for ongoing maintenance and dispensing into deep filler necks.
  • 1 Litre is a great dispenser for boats, trucks, and machinery where the filler is clear and accessible.
  • 5 Litre is great for dispensing into small-to-medium sized storage tanks and large vessel/machine tanks.
  • 25 Litre is most convenient for bulk usage or re-filling smaller bottles as it has a tap supplied with the cube.
