I am reviewing the data collected from the trials run in 2015 on the buses run by “C+M Coaches” in a controlled trial run with and without the additive Dipetane.
There are ongoing trials from August onwards which we hope to publish in full shortly.
The current indications are a 17.8% increase in fuel efficiency after the addition of the Dipetane fuel additive. Thjer are also some emissions showing a 31% decrease in NOx at 2,000 revs on an Optare Solo bus.
The drivers are also noticing an increase in torque on the steep hills.
