What You Need to Know About Gearbox Oil Maintenance


Whilst engine oil is obviously beneficial to the running of a car, gearbox oil is typically overlooked. In fact, most motorists do not give the needed consideration to this essential fluid. Because the oil is rarely seen and generally does not cause issues, it is considered innocuous. However, the opposite is true. If anything goes wrong with a car, the oil can be hazardous.

What Is Gearbox Oil?

To acquaint yourself with this type of oil, you need to know more about its purpose. It is a lubricant that is located in the transmission system. Therefore, it is meant to lower the wear and tear on the internal mechanism. The oil emits a strong and noticeable sulphur odour. It normally contains extreme pressure-type additives so that higher performance can be obtained.

How the Oil Is Used

The oil that is used in gearboxes in Gravesend is made with a higher viscosity than the oil found in the engine. As a result, it more ably safeguards the gears and ensures a streamlined transition between them. The viscosity is also vital as no pump is located in the gearbox to move the oil. Only the lowest of the gears are immersed in the lubricant.

When the Oil Should Be Checked

As a result, there can be somewhat of a debate as to when the oil needs to be changed. Some repair experts recommend that the oil be changed every 80,000 kilometres. Regardless, a healthy oil should be tinged red in colour and should never emit a burning smell.

If you hear a grinding sound from the clutch or feel the gears slipping, you are being warned that your oil is faulty and should be inspected without fail. A defective fluid can be very damaging to both the gear operation and the transmission, which leads to a lower gear-shift response and possible corrosion of the mechanics.
