I have a Landrover Freelander TD4 less then a year old. I have noticed that
my local BP service stn is selling Diesel Ultima which cost about 3 pence
per litre more than the regular diesel. I asked the benefits and was told
that it provides less pollution and gives much better performance. I decided
to test it in my vehicle.

Findings:-

No noticeable increase in performance, in fact I believe performance was
reduced.
About 12% less MPG.

This means that given the increase in cost and the reduced fuel economy my
fuel bill will increase by about 15% or 55 pence per gallon. It seems to me
that BP will be making a lot of money out of the motorist who uses this
fuel. Needless to say I have reverted to the normal diesel for me to use
ultima it would have to be priced at least 10 pence less than the ordinary
diesel.

Anyone else using this fuel found the same.

I too have a Freelander diesel, pre-TD4 model.

Diesels are by their very nature a filthy means of arranging
transport, and in my view any internal combustion engine is. Whilst
I'm okay on the idea of ensuring that the pollution my car produces is
minimised in line with government requirements I would treat any
claims of some magic snake oil making it cleaner with a great deal of
scepticism. If it was that good then government would legislate that
it must be used.

My fuel performance is about 30mpg - and my right foot isn't exactly
gentle with the accelerator most of the time. I would treat any claim
for improving the capability of the engines mpg with the same amount
of scepticism.

Snake oil salesmen are still earning a living.

One effective way of improving a diesel is dual fuel.. injecting LPG into
the air intake which when ignited by the diesel sparking off in the
cylinder, casues more even burning and less unburnt diesel out the pipe.

power increase can be anything up to 30%
