Hi Steve, Have you run the Landy on a gas analiser with the HHO running at the MOT station? Reason I ask is that I'm running a 300tdi within the M25, and will fall foul of the TFL regs. in a couple of years. Do you think that HHO could 'water down' (excuse the pun!) the emissions to comply with euro iv ? I'm already running a 'Smartveg' veg. oil conversion - but that's not green according to TFL!
