Background

Misleading Advertising: the hydroxsystems.co.uk website breaches the UK Advertising Code for making unsubstantiated efficacy and efficiency claims for HHO fuel saver kits.

Section 3 of the CAP Code states that marketers must hold documentary evidence to prove claims that consumers are likely to regard as objective and that are capable of objective substantiation; Section 11 of the CAP Code states that absolute claims must be supported by a high level of substantiation.

To date, neither the ASA nor CAP has seen evidence to demonstrate the efficacy or efficiency of HHO Fuel Saver Kits.  

A rotating banner on the homepage of the hydroxsystems.co.uk website makes two problematic claims for their “HHO fuel saver kits for all combustion engines”:

  • “Up to 30% Fuel Saving”
  • “Over 80% Less CO2 Emissions”

In order to comply with the Code, the hydroxsystems.co.uk website should remove all misleading efficacy and efficiency claims for their HHO fuel saver kits, unless they hold robust substantiation for such claims.

The CAP Compliance team contacted Hydrox Systems UK several times to seek an assurance that, in the absence of robust supporting evidence to substantiate them, efficacy and efficiency claims would not be made for their HHO Fuel Saver Kits. In the absence of a response, the CAP Compliance team took the decision on 19 March 2018 to place the Hydrox Systems UK company details on this section of the ASA website. These details shall remain in place until such time as Hydrox Systems UK has removed or appropriately amended the problematic claims on hydroxsystems.co.uk to ensure compliance with the CAP Code.
