Fuel Cat? Do they work?

when fitted. Surely they cant work. If they were so good why
doesnt every manufactuer fit them as OEM?
Anyone fitted on and got good (or bad) results?

They come into the category of 'snake oils'. Do not waste your money on
these things.
Keep your engine well serviced, and in good tune, that alone will keep
your MPG and power to normal levels.

which then has to be recovered from the sales price of the cars sold by
putting the price up. If these devices worked, the manufacturer would spend
£5 per car and get a "10% or better" improvement in power and economy. As
yet, no manufacturer in the world fits these devices to a new car. Point
proved? If any manufacturer of these devices would care to publish their
research and explain how they work (including the chemical equation for the
reaction which these catalysts are supposed to cause) I would be delighted.

You don't think the manufacturers use these things to *up* the
official MPG tests do you?, and then not bother fitting them to the
production cars to save a fiver, cos the figure in the handbook are
always 10% higher that real life........................ ;-)

As the yourself and the other posters, I class these as snake oil. I was
surprised and disappointed when my (normally trustworthy and competent)
mechanic recommended one for my 1987 1.3 Orion...
Apparently, a couple on the market did seem to have a positive effect in a
single independent test, but this isn't really a scientifically reliable test.

Nope. :)

Alex.

tests they always start with the engine at optimum temperature and engineers
have gone over the car with a fine tooth comb so that there is no drag from
any brakes, the tyres are pumped up hard for less rolling resistance etc.
all perfectly legal but no relation to the conditions under which we drive
the car every day!

Indeed, but just in case you thought I was being serious, I did end my

My diesel engines have given better figures after 15-20k miles as everything
settles down and beds in, but still nowhere near the manufacturers figures
(who drives at 56mph all the time anyway!)

Before installation the car was tuned and gas measurments taken. CO
was 1.5% and HC was 300ppm as i remmber. Anyway when it went in the
feul line we ran it for 5 mins and checked the gas readings again. CO
0.5% HC 80 ppm, the next time it went for an MOT the guy doing the gas
test checked 3 times to make sure the gas sniffer was in the exhaust
because he couldnt understand how the readings were so low.
The car averaged 40 to the gallon with this thing on even tho
in typical GTE style i thrashed the balls out of it everywhere.
The place that fitted it was a very well respected Bosch
tuning agent. All the taxi drivers in the surrounding area had them on
, deisels everthing. He never had one complaint from them.
Its a pity that they are marketed so badly (high pressure
triangle market stuff).
The technology dates back to WW1, they were used on spitfires
to raise the octane level of the fuel.
Do they work ????, who knows , i say the gas readings on my
car.

If the rest of your sales pitch is as accurate as this..............

Bear in mind that the Urban test involves a cold start and the ExtraUrban
follows immediately after with varying speed upto 70mph. It's no longer the
56 and 75mph test y'know! ;-)

Yeah yeah, i personally could care less wether anyone buys these
things or not. I was answering the original question as to good or bad
rep for thse products.
It seems that im the only one who has any experiance who
answered anyway, the rest of you dont need to actually to know
anything about a subject to have an opinion. Thats very scientific.
Very smart.
I know what i saw on lots of differant gas anaylysers over the years
