No. Light diesel is used as the sealing oil, as it has a low density; whereas the medium used for reprocessing oil has a high density and high viscosity, resulting in poor sealing effects.

Medium-grade oil has components similar to light diesel, but sealing oil requires low temperatures, which medium-grade oil cannot meet
