Don't bother, it won't do anything positive to your engine, performance or even economy...

Just reading an old thread on this and there appears to be lots of varied opinions.

You say this from scientific research you've done? Or as I suspect you're on the "I've heard it, it must be true" bandwagon. (_;)
Fact, I have an MX5 that 2 years ago failed miserably on emissions, I tried stripping and checking loads of parts, all did nothing on rechecking. I then poured half a bottle of this in the fuel tank and took it for a good spin and hey presto, next day it flew through the emissions. It did again this year too. So, IMHO, anyone saying it does nowt is talking bo**ocks.

Edit to say, just remembered, my mate had exactly the same problem this year with MOT emissions and cured it in the same way. 2 out of 2 aint bad.

HOT deal,

I put this in my old MX5 of 18 years old every MOT and it passes the emissions everytime (it did struggle previously with high figures and a long revving engine) - it sails through now.

I'm a very suspicious person by nature - but this does do something .....

I've heard this is no good is you have a dpf? Apparently

If you are unfortunate enough to have a dpf then you won't need this for your MOT - as your dpf will have written off your car before it is 3 years old .................. horrible, damned things!

good value heat added

couldn't have said it better. how can cars pass as low emission only to let all the emissions out on the motorway or country road?

Although I agree that DPF's are stupid and just another time bomb waiting to cause issues down the line... they hardly write your car off... unless you assume you have to replace them with another official DPF circa $1500 to get you through an MOT. As far as I know the DPF isn't tested or forms part of the MOT. The emissions it "reduces" (soot) don't qualify for failure of an MOT. The DPF on my 06 Ford Focus blocked up completely about 7 months ago ( after around 95,000 miles at the time). I had it "removed" (actually they ram a pipe through it and put it back on rather than actually remove it) and the ECU "tweaked" to ignore all the DPF signals etc. Cost me £400 and its had an MOT and Service at a Ford Garage since then and passed no problem, they weren't even aware anything had changed. They probably still filled up the DPF oil tank ..LoL.
Its now done 104,000 miles and still going... now the next ticking time bomb (on all newer diesel cars) is the dual mass flywheel.

Was thinking of getting my golf gt TDI converted from DMF to a single flywheel to allay any future problems. Will report back after I've used this. At £2 may get three months worth which will give a more balanced view

Quoting from experience?.

I'll quote mine for the record, 3 x Mazda 6 diesels (2006, 2009 and now a 2013) all with DPF and no failed DPF here.

Sounds like sour grapes to me!

Wouldn't quite say it destroys the car but it definately uses more fuel due to the regeneration process. Also if you don't take your car on a motorway sprint, ie above 60mph for at least 10 mins every 2 weeks, the dpf will slowly get blocked up. This will make your engine run slower and less responsive make you use up more fuel. For all the dpf lovers out there, what saving in emissions is that?

Would you spend £400 On a £1200 car to get rid of (not even replacing or fixing) a stupid contraption that doesn't reduce net emmisions but actually increases them?

£2 in TESCO too!
