Step-by-step application

Simply pour the contents of the can into the tank before refueling.

Tank filling 1 can of MATHY-D
Tank filling 1 can of MATHY-AGRR
Tank filling without
Tank filling 1 can of MATHY-AGR

Tank filling 1 can of MATHY-AGR

To start the EGR treatment, drive until the fuel tank is almost empty and add one can of our MATHY-D diesel additive diesel system cleaner to the tank before refueling. Now run the first cleaning cycle. During this phase, contaminants in the combustion chamber and on the injection nozzles are broken down.

Once this cycle is complete, our MATHY-AGR cleaner comes into play. To do this, add one can of MATHY-AGR to the empty tank and fill it with 50 liters of diesel fuel. Drive until the tank is empty. Then fill the tank once without MATHY-AGR and then again with MATHY-AGR until all three cans of the treatment have been used up.

For an optimal cleaning cycle, we recommend a 30-minute drive on the highway with MATHY-AGR in the tank.

MATHY AGR Set

Simple diesel and EGR (exhaust gas recirculation valve) system cleaning

Products 1 x 250 ml MATHY-D + 3 x 300 ml MATHY-AGR

Application without visiting a workshop: Once a year directly via the tank

* Important note: Exhaust gas recirculation valves (EGR) that are already completely coked up can no longer be cleaned with MATHY-AGR. If the engine warning light is already partially or permanently illuminated (yellow), MATHY-AGR cannot help here either. In these cases, the EGR valve must be removed or cleaned manually. We recommend using MATHY-AGR as a preventive measure!
