WhenI first heard about Dipetane I was sceptical,probably just like most people.Before I invested my hard earned money and time I needed to try it.After a few days of trying Dipetane in my car I realised something was happening. my mpg improved,eventually peaking at just over 11% improvement.I have been selling Dipetane for over six years and have never had or heard of a problem,only good news and happy customers,varying from Independent fuel distributors to individual customers who wanted to save money.Dipetane is not a fuel additive but a fuel treatment, an advanced fuel technology helping to protect the environment by controlling emissions and producing significant fuel savings in the UK. Savings of over 10% can be expected,with reductions of smoke (50%) ,CO2,Nox and PM10's by 25%).One litre treats 200 litres of heating oil,kerosene,diesel or petrol.Save money and help the air we breathe by using Dipetane.There are no downsides .Fully insured with over 15 years clean record.
