Question 171Motor Plants - QMED

The correct answer is B) high temperature and a low viscosity. When the oil is at a high temperature and has a low viscosity, it will be most effective for oil cleaning and filtration. This is because the lower viscosity of the oil at high temperatures allows it to flow more easily through the filter or centrifuge, allowing for more efficient removal of contaminants and impurities. The other options are incorrect because: A) High temperature and high viscosity would make the oil more difficult to filter and clean effectively. C) Low temperature and high viscosity would also make the oil more difficult to filter and clean effectively. D) Low temperature and low viscosity would not be as effective as high temperature and low viscosity for oil cleaning and filtration.
