Comma Diesel D-Tox Fuel System & Injector Cleaner

Harmful deposits gradually build up and clog up fuel injectors which can seriously affect engine performance.

Comma's Diesel D-Tox (DDTOX400M) is a highly concentrated heavy duty fuel system cleaner formulated to rapidly remove these deposits whilst acting as a powerful cleaner throughout the whole system, including diesel injectors. The cleaning action works whilst you drive and effectively restores lost power and acceleration.

Ideal for use with ultra-low sulphur diesel fuel, but equally suitable for all light and heavy duty diesels including TDI, CDI and HDI types, as well as turbo charged engines. Can also be used in common rail fuel injector systems.

Usage Directions:

  1. Pour entire contents into fuel tank prior to refuelling
  2. Placement of Diesel D-Tox directly into the fuel filter is not recommended
  3. For ongoing protection, use Comma Diesel Magic
One 400ml bottle is sufficient to treat 60 litres of diesel fuel.

We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
