Frequently Asked Questions About Lubricating Oil

Solve Common Industrial & Engine Lubrication Problems

In daily equipment operation and maintenance, users often encounter various lubricating oil problems, such as oil overheating, oil foaming, oil blackening, insufficient oil pressure and short service life. These common problems will affect production efficiency and even cause equipment failure if not solved in time. This article sorts out the most frequent lubricating oil problems and professional solutions.

Q1: Why does lubricating oil turn black quickly?

Rapid blackening of oil is mainly caused by excessive carbon deposits, metal wear debris and oil oxidation. Long-term high-temperature operation, dirty oil circuit and overdue oil use will accelerate blackening. Solution: clean the lubrication system thoroughly and replace with new high-quality lubricating oil; shorten the oil change cycle for high-temperature working conditions.

Q2: Why does lubricating oil produce foam?

Foam is usually caused by unqualified oil formula, water entering the oil tank, excessive oil filling or damaged filters. Foam will lead to insufficient oil pressure, poor heat dissipation and accelerated oxidation. Solution: use anti-foam lubricating oil, control filling volume and keep the system sealed and dry.

Q3: Can different brands of lubricating oil be mixed?

It is not recommended to mix different brands or different types of lubricating oil. Different additive formulas will conflict, resulting in oil deterioration, sludge and reduced anti-wear performance. For oil replacement, drain all old oil before adding new oil.

Q4: What causes lubricating oil overheating?

Overheating is caused by improper viscosity selection, excessive oil quantity, blocked oil circuit, heavy-load overload operation or poor equipment heat dissipation. Long-term high temperature will cause oil failure and equipment wear. Solution: select matched viscosity, clean oil circuit and adjust equipment operating load.

Q5: How to choose lubricating oil for seasonal temperature changes?

In winter and low-temperature areas, choose low-viscosity and low-freezing-point lubricating oil to ensure good fluidity and easy startup. In summer and high-temperature environments, choose high-viscosity and high-temperature resistant oil to prevent oil thinning and lubrication failure.
