Maybe interest in LPG or Autogas as it is known , will be rekindled. I run my Range Rover on LPG as we sell it and its performance is fine as are the emissions . At about 70/75 pence a litre its much cheaper than petrol . Years ago one of the major fuel companies advertised a little alcohol in their product , if it was ok then why not now ?
In high enough concentrations bio-ethanol can corrode rubber (seals, pipes, etc). There are alternative materials that can withstand the damage but they haven’t been mandated fitments, only some manufacturers have used them anyway as globally bio-ethanol now has a bigger market.
