1- Oil will not lubricate over sludge ,dirt on any other contaminants. The oil just moves to the first area of clean metal it finds and lubricates.
2- Friction Reducers Work The Same Way
3- So if you can't provide clean metal why waste your money ?
4- BTW Auto-Rx not only gives you clean metal we also provide friction reduction.
5- How ? Because every metal area can accept oil after being cleaned by Auto-Rx ( oil is what Auto-Rx uses in your engine as a carrier)
6- Auto-Rx is not a solvent we don't change the chemistry of your oil or the viscosity.
