MATHY Fuel Additives – The Performance Advantage for Fuels!

Fuel Additives

Why fuel additives are necessary and very important

The increasing organic content (bio fuel) in current fuels (E5, E10, E20, E85 and B7) basically entails an unclean combustion, which leads to more deposits at the injection nozzles. This results in a decreasing performance and efficiency of the entire fuel system, causing a rough engine run and increased fuel consumption.

Keep your fuel system permanently clean with a simple application via the fuel tank.

Problems with deposits and residue formation can only be solved by a regular cleaning of the fuel system! The specific optimization of fuel-carrying components counteracts the negative influences of fuels with organic content.

Advantages at a glance

  • Cleans the entire fuel system
  • Improves starting behavior
  • Reduces pollutant emissions
  • Optimizes fuel consumption
  • Reduces extensive repairs

How do MATHY-Additives work in the fuel system?

Additives can easily be added to the fuel system in order to enhance or improve different properties, like increasing knock resistance, improving the combustion process, cleaning and keeping clean the fuel system (including valves and combustion chamber), enhancing storage life or improving the cold properties of diesel fuel (see winter diesel, cloud point, cold filter plugging point).

Frequently asked questions

What are the benefits of using MATHY fuel additives?

The highly concentrated MATHY fuel additives carefully decompose deposits, the combustion process becomes cleaner, and fuel consumption is optimized. The CO load is substantially reduced and system failures due to soiled and coked fuel systems are prevented.

Can I apply MATHY fuel additives myself without workshop visit?

MATHY fuel additives can easily be added to the fuel tank prior to refilling. A workshop visit is not necessary for this application.

What fuel additives does MATHY offer?

Due to the long-standing experience in automotive fuel additives MATHY offers products / system solutions for the following areas: diesel, bio-diesel, petrol / gasoline, exhaust gas cleaning, diesel particle filter, vegetable oil, and diesel flow improvement (winter).

Are MATHY fuel additives able to resolve technical problems?

The use of MATHY fuel additives can prevent technical problems at fuel-immersed components, optimize fuel consumption, and balance power loss.

Diesel Particulate Filter Cleaner

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!

MATHY-AGR Diesel Cleaner for Exhaust Gas Recirculation

System cleaner for the exhaust gas recirculation

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!
