Passing the pollutant gas control at the ITV, decarbonisation of FAP and EGR valves.

Regardless of its age, a diesel vehicle using C99 will pass the roadworthiness test with an average opacimeter reading of 0.50 points (in passenger cars or users). Mecarun is able to offer the following guarantee:

Less pollution means less fuel consumption.

• Allows for finer atomisation of the fuel (fogging).
• Increases the velocity of the mixture of oxygen and hydrocarbons.
• Reduces the presence of sludge in the fuel tank (diesel).
• Reduces gum and varnish deposits in petrol.
• Increases the speed of the flame front.

Metering on road and mixed routes

•10 ml for 40 litres - 15 ml for 60 litres - 20 ml for 80 litres

Dosage on urban circuits and short distances.

•Vehicles with FAP, EGR valve with carbon deposits: 1.5 with double dose of C 99

how to pass the MOT test

Avoid replacing EGR (400 to 600 € uro) or FAP (800 to 1500 € uro).

MOT gas control: up to 60% below the maximum tolerated standards, MOT success

C 99 is the preventive anti-carbon solution for EGR, FAP and Turbo valves, thanks to perfect combustion.

How to understand the C 99:

C 99 contains an antibacterial that will keep the diesel free of micro-organisms and sludge. C 99 generates a finer injection beam, thus achieving what is considered perfect combustion (see testimonial pages for exceptional results in pollution reduction and fuel economy with a dose of C 99 at every fill-up).

1 - C 99 minimises carbon build-up in the engine (saves replacing the FAP, EGR valve, Turbo and costly intake duct cleaning, etc.).
2 - C 99 prevents sludge and bacteria in the tank and prevents seizure of pumps and injectors.
3 - C 99 saves even more fuel in older vehicles and helps to keep the engine cleaner (see testimonials).
4 - C 99 at each fill-up prevents your engine from seizing (double dosing on urban circuits).

Total security in the quality of your fuel

C 99 helps the fuel to meet all quality controls in the petroleum products regulations.

C99 has been verified by a COFRAC approved laboratory.

Technical control reports of pollutant gases in authorised centres.

Consumption reduction measures certified by professional and private users.

• C 99 modifies the surface tension of the fuel molecules (carbon chain type C6) in order to obtain a homogeneous distribution of the oxidant/fuel mixture which improves combustion and optimises engine parameters. C99 is not a fuel additive according to regulations / Art. 236 of the customs code.

• The C 99 allows for better fuel nebulisation, which increases the surface area in contact with oxygen and allows for better combustion (video below).

•  C 99 increases the flame front velocity for better deflagration, as demonstrated by anti-pollution tests on vehicles of all ages.

•  The part of the fuel that was previously wasted is now used to add energy to your engine. Your vehicle consumes less fuel, pollutes radically less and stays cleaner, even in city traffic.

• C 99 reduces fuel consumption (see user testimonials).

C99 petrol (All Petrols)

How it works  :

C 99 modifies the surface tension of fuel molecules   (carbon chain type C6) to obtain a larger contact surface with oxygen and a homogeneous oxidant/fuel mixture, achieving ideal combustion and improving the operating parameters of thermal engines.

C 99 accelerates the air/fuel mixture at any engine speed, hot or cold, achieving a much more homogeneous injection beam at ignition and a very high combustion speed, converting all the fuel into energy, so that the money you save is no longer wasted through the exhaust in the form of polluting black fumes.  Remark: Incredibly, MOT measurements of pollutant gases show a 4 times lower reading of Hc and Co.

C 99 Petrol is also equipped with an anti-friction feature which prevents seizure and clogging of the injection system or carburetion. C 99 Gasoline avoids deposits from rubber and lacquers that foul the tank and injectors and are also responsible for seizures or blockages in the engine's fuel system (see photo).

C 99 Petrol achieves CO readings below 0.005 in the ITV test.

For this reason, Mecarun offers you the following guarantee:

ITV gas check: If you are not satisfied, you get your money back!

Less pollution, less fuel consumption

C 99 avoids the corrosive effects of ether and ethanol

(see detrimental effects on pipes and seals).

The anti-friction function of C 99 is a great advantage.

Protects the fuel system right up to the firing segment and reduces the loss of lubrication of current petrols in accordance with Euro 3 and Euro 4 standards.  It prevents fouling of the lambda sensor or loss of charge in the injection pump due to the usual heavy wear caused by ethanol, water, alcohols, lacquers, rubbers and corrosion.  The amazing functions of the C 99 Gasoline achieve good engine performance and keep the lambda sensor clean. It is specially designed for cars, boats, ultralight aircraft, quads, scooters and all 2 and 4 stroke engines.

C 99 Petrol achieves a quieter engine. Reduces or eliminates detonations of unburned fuel in the exhaust. Gasoline storage: C 99 allows slowing the octane drop caused by prolonged storage. Some state agencies will store it for up to 5 years.

C 99 reduces Co² emissions and fuel consumption: see our testimonial pages. C 99 Petrol allows you to save money that would otherwise go down the drain and pollute the environment. C 99 avoids maintenance operations caused by carbon build-up and engine fouling,

C 99 Gasoline avoids damage caused by electrolytic torque which corrodes metal in the injection system and carburation. Methyl tert-butyl ether or MTBE with formula C5H12O is a colourless, volatile, flammable liquid ether that is not miscible in water.

C 99 and hybrids

C 99 reduces fuel consumption and pollution when starting the engine (see anti-pollution testimonials). The initial wear of the engine is due to the lack of lubrication during the first rpm. P18 antifriction prevents this.

Likewise, hybrid vehicles and those equipped with the Stop and Start system tend to suffer from wear due to continuous state changes from electric to motor mode. C99 and P18 are ideal in this circumstance to lower consumption and prevent engine wear.

1 gram of petrol burned emits 3.09 grams of CO2 x mass of petrol = 2.28 kg of CO2 per litre of petrol burned. 2228 gr / 120 gr = 19 km per litre of petrol = 5 litres / 100 km

C 99 reduces Co², HC and CO. The catalyst converts carbon monoxide to carbon dioxide: 2CO + O2= 2CO2:

C 99 reduces CO emissions by up to 4 times and keeps the lambda sensor clean, allowing optimum engine performance (see Yamaha XMAX and other petrol vehicles report on Mecarun's anti-pollution page). Oxidation of unburned hydrocarbons (HC) to carbon dioxide and water: 4CxHy + (4x + y) O2= 4xCO2 + 2yH2O:

C 99 reduces carbon and pollutant gases

Without C99 - lambda probe - with C99

injection pump flow

Oxidation reactions 

require a high oxygen supply, in contrast to reduction reactions. The reading of this reaction is taken by the lambda sensor, sending the data to the engine management computer. The C 99 keeps the lambda sensor clean and operational for optimum performance, as well as allowing minimum fuel consumption.

Fuel economy is key to pollution reduction in cars, motorbikes, heavy duty vehicles, trucks, marine, tractors and agricultural machinery.

C 99 reduces carbon build-up in the catalytic converter, EGR valve, FAP particulate filter and turbo. Mecarun means ecology, environmental protection, elimination of carbon and black smoke, success in MOT gas control and reduction of water, bacteria and sludge in the tank.
