Over time, all sealing materials lose their plasticizers (elastomers). This process is further supported by continuous hot and cold temperature changes. As a result of this insidious process, seals / gaskets begin to contract, increasingly harden, and finally even break. As a result, a loss of oil can no longer be prevented!
DropStop contains high-grade plasticizers (elastomers) that are compatible with every kind of oil (mineral, partly or fully synthetic). By adding DropStop to the oil, the plasticizers directly reach the seals and can penetrate them or can be absorbed by the sealing material. The seals swell and become elastic again. Potential wear at shafts can be compensated for and the seal lips seal properly again. Loss of oil due to leakages at elastomeric seals can be fixed this way.
DropStop can be applied to units / machines like engines, compressors, hydraulic systems, transmissions etc., in which mineral, partly or fully synthetic engine oil, gearbox oil as well as hydraulic oils are used.
DropStop is suitable for all rubber and neoprene seals that are based on elastomers.
DropStop is not suitable for seals made of packing material, shaft seals made of graphitized ropes with asbestos, flat gaskets made of paper, cork or metal (e.g., cylinder head gaskets) as well as for cracked materials.
No, DropStop does not cause any damages. No sealing material, whether old or new, is damaged by DropStop. Furthermore, DropStop does not contain chlorine or other solvents that could damage the treated units in the long run.
Without question, you can use MATHY-DropStop in your motorcycle. All elastomeric seals / shaft seals become elastic and sealed again. MATHY-DropStop is mixable with all mineral and synthetic oils.
The question what type of oil is used in a power steering is irrelevant with respect to DropStop because it can be used with all types of oil; it takes effect at the elastomer sealings / gaskets.
Usually, the power steering of cars has an oil filling capacity of 0.9 to 1 liter of oil. For adding DropStop this is irrelevant because 250 ml can safely be added without affecting the function of the oil.
Both products are completely different in their modes of action because their compositions are based on totally different additive packages. Combining the two additives could cause the whole the oil composition to become unstable. However, the separate use of each product in combination with MATHY-M is possible.
How fast DropStop takes effect depends on the amount of elastomer (plasticizer) the seal has lost already and thus, how much has to be returned or absorbed again. DropStop reaches its full effectiveness after two weeks of regular use of the machine. If after that time no noticeable improvement can be seen, there is most likely a mechanical damage of the seal. It has probably cracked. In this case a disassembly is necessary. If only a slight improvement is noticed you can safely add more DropStop so that the seal can absorb the still missing plasticizers.
For most vehicles it is common knowledge that they will experience oil leaks after the sixth year in service. More exact information with respect to certain types and brands of vehicles can be found in the relevant internet forums.
It is recommended to start a preventive use of DropStop in the fifth year in service of a vehicle.
