You can Hover on the Highlighted text and a small box will appear, explaining more about the item in question.

The same format is used throughout, so it is easy to understand and compare results for different vehicles.

For more information about how to test Vehicle Emissions you can visit the ‘Emissions Test Procedure’ page.

*Economy Data is presented accurately. Please remember the Wucube is sold as an Emission control device only.

An standard emissions test is taken at two speeds which are a Low speed and a High speed.
The Table below is an example of the Results gained from a single Emissions test

The Economy Table is a direct comparison of Economy Before & After the Wucube.
The Economy data is ONLY based upon actual fuel consumption (Litres Pumped vs Distance Travelled).

For more information about how to measure Fuel Consumption you can visit the ‘Economy Test Procedure’.

Each Emission test has a Before & After Wucube which yield a % Difference exampled in the table Below

The Wucube was a prototype and the tests were performed in August 2015.
The Economy test was performed on the M5 Motorway, with cruise control set to 60 mph, without traffic. It was this test on my own Vehicle, that convinced me the Wucube was a good thing…
The Emissions test was performed the week after and this just blew my mind and left the mechanic shaking his head!
I didn’t notice any increase in power at all, but the car was pushing 250bhp at peak already.

I drive from Exeter to Coventry every two weeks to see my mum and before the little box was in my car it used to cost me £45. Now it only costs me £35.
I’ve worked out that since the box was put in my car I have saved a total of £180 just from this trip over the last 9 months! I don’t use the car much at home because I’m a pensioner, but every little helps, and I’m really happy about this.
The man in the garage said my car is running much better too. Thanks.

I was asked to test a Wucube by my Daughter because she knew I was a mechanic before retiring from work. I noticed straight away the engine was quieter and that my engine seemed more responsive on acceleration. At 1st it was hard to believe but after several tanks of fuel it was obvious the car was using 1/4 tank less than it did before. It definitely works better on longer journeys.
I took my car to get tested and then it all made sense. Amazing really. (Translated from Polish)

This Car was hired for a week in order to see how the Wucube worked on a very new and economical vehicle. It seemed like a good idea to use a VW considering the news around the time.
The emissions test was performed under load at 45 mph on cruise control using a handheld Crypton gas analyser. The economy test was performed on the Motorway over 1200 miles @ 65 mph.
The results shocked me but speak for themselves…

Had my car for a couple of years and was aware it used a lot Petrol which is why I used Gas most of the time in England, it was much cheaper.
After one Wucube was put in the boot I went to the airport to pick up my friend and then drove to Cornwall. It was exciting that for £50 the car would go for 470 miles.
This made it cheaper to use Petrol instead of gas, but I haven’t tested the gas yet. (Translated from Polish)

We own a garage near Heathrow and we offer car hire. Ian from pdf was hiring a lot of cars from me and I asked what he was doing. We ended up having a bet that his device could not reduce the Emissions in a Fiat 500, because it is such an Eco-friendly motor.
I got my mechanic to test the emissions for me in the MOT garage and we were all shocked, as it just seems impossible that it could even do anything.
Needless to say I lost the bet but ended up with a free Wucube! Cheers and good luck.

The Berlingo is used for U.K courier operations, on lease, running around 1400 miles a week on a multi-drop. Nothing too heavy but fully loaded every morning. The Diesel is my biggest cost really after the lease, so I was really interested in this Wucube thing.
I tested it over 10 weeks and it really worked. It shaved about 1/4 off my Diesel bill, which goes straight in my pocket. Most of my driving is Motorway junction to Junction to Industrial estates.
My son is happy about our lower carbon footprint too as he was bothered.

I work in the control station for cars in Ryki and we are connected to the college where we train mechanics. I am a qualified emissions tester and been a mechanic for 25 years.
I was really interested in the device because it was supposed to reduce the emissions without touching the engine or being in the fuel tank. Hard to belief?
I knew my own car and so decided to test the device on it, and afterwards was simply baffled by the results, so I measured my fuel for months also. (translated from Polish)

After testing the wucube on my own car I borrowed this one from my son-in-law, to see if it worked on another car that was a different make and newer than my own. I also wanted to test it on Lpg. Well it did work and he is still saving money because he kept it. (Translated from Polish)

I was never interested in saving fuel because I don’t drive very far these days. But my car is a bit of a dirty beast, being pretty old and having a big engine. In good nick though as I’m a mechanic.
My mate is an Mot tester so I knew I could test the device quickly and see if it really did work or not, although I thought it could because it makes sense when you think about it.
I am really happy with the results and glad I bought this because it’s like a new car.

I have a business in Poland and I tested the wucube to see if it worked, so hopefully I could start selling them to my customers and other people.
After trying one I was amazed and still trying to figure out exactly how it is working. This is my car running on gas, but I have tried it on my wife’s new Diesel car and this car on Petrol too.
It just works. I am not sure how but it does. (Translated from Polish)

I have had this car for years and know exactly how much fuel it uses to go so far. I put the cube in my car and the first long trip was to Gdansk which I had done many times, to my seaside house. Before I always needed to stop and fill up the car as the trip used more than a tank, but since the cube was inside my car I don’t even need to stop. (Translated from Polish)
