Millers Oils Eclipse Diesel Fuel Treatment Additive

A revolutionary fuel additive that not only increases fuel efficiency, thereby reducing overall fuel costs, but also lowers emissions and cleans injectors.

Designed to work with all types of diesel engines, especially Euro IV Euro V and Euro VI emission compliant vehicles. It is also backward compatible with Euro III and older type vehicles and mobile plant. Can be used by adding it to the bulk fuel tank or individual vehicle tanks in the ratio 1 part to 1000 parts fuel (1ml/Litre).

Please note that we are unable to send this product or any other diesel cetane booster to destinations outside the UK.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
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!).
