MATHY–D cleans the diesel fuel system and improves operation reliability and economy of diesel engines. Suitable for all diesel engines (CDI and TDI) and diesel fuels, summer and winter quality. Suitable for all diesel oxidation catalysts and micro particle filters (DPF). It is also compatible with AdBlue.

MATHY-DPF lowers the combustion temperature of the soot in the particulate filter (DPF) and thus prevents skipping of the regeneration process in the DPF. The full absorption capacity of the diesel particle filter is restored, even at low operating temperatures.

Important note:
MATHY-DPF can no longer be used as a cleaning agent if:
- the diesel particulate filter (DPF) is (already) completely filled with ash, 
- the engine control lamp (yellow) is partially or permanently lit, 
- the engine is running in the emergency program. 
In these cases, the diesel particulate filter must be replaced or burnt free by a specialist workshop. We recommend using MATHY-DPF as a preventive measure!

Regular use of MATHY-AGR in diesel fuel reduces a build-up of carbonaceous residues in the exhaust gas recirculation system and therefore repairs are minimized. Impurities are chemically degraded over the exhaust stream. Malfunctions, caused by a soiled exhaust gas recirculation valve can thus sustainably be prevented.

Important note: 
Fully coked exhaust gas recirculation valves (EGR) can no longer be cleaned with MATHY-AGR. Also, MATHY-AGR cannot take effect if the engine control lamp is already partially or permanently lit (yellow). In these cases, the EGR valve must be removed or cleaned manually. We recommend using MATHY-AGR as a preventive measure!

MATHY-ID is an intensive and instant injector cleaner for diesel vehicles. Impurities at injectors and / or nozzles are dissolved. This process restores the spraying pattern and entails an optimized fuel consumption.

MATHY-BE is a specially formulated fuel additive for all fuels in petrol / gasoline engines. The active component combination for ethanol, petrol and ethanol-petrol blends has a highly effective cleansing and maintenance effect. MATHY-BE prevents damage to the fuel-carrying components. Possible deposits which reduce the efficiency of the fuel system are dissolved and burnt residue-free.
