My heating oil supplier here in Cumbria is promoting something they
call "Cleanburn" heating oil. It's claimed to be upto 13% more
efficient

And how much more expensive is it than bog standard 28sec?

The product is described here http://www.kellyfuels.co.uk/kf2.htm.
Has anyone used this oil and found the claims justified?

Well It all reads very nicely but read what is written closely and it
doesn't really stand up IMHO. For instance the highlighted
"testimonial" towards the top of the page:

"Since changing to Cleanburn I find the house much warmer and have had
to turn the temperature down making it more economical - even the
boiler needs less servicing".

How does changing the fuel affect the temperature of the house
controlled by a thermostat? Of course if you turn the stat down by a
couple of degrees you will use less fuel "making it more
economical"... Boiler servicing, well that is debateable ours gets
done every year but I'm not convinced it *really* needs it that often
burning ordinary Shell 28sec oil.

Not that none of the "testimonials" are credited.

Why no link to the University of Ulster research? The only link is to
the makers of the addative, they are not likley to be unbiased are
they...

Shell have been marketing a 28sec heating oil with similar claims for
the last couple of years. I've not been convinced by any one that the
extra cost is really worth it.
