How long does differential/transmission oil keep?

The differential is usually located at the back of your vehicle and under the vehicle. It is very important that it stays lubricated with differential or gear oil to keep it working properly and your car moving smoothly on the road. The oil must be changed every 30,000-50,000 miles, unless otherwise noted in the owner's manual.

The differential is the part of the car that compensates for the difference in travel between the inside and outside wheels when cornering. If you have a rear wheel drive car, your diff will be in the rear with its own lubrication and housing. He uses a dark, thick oil that is heavier than 80 wt. Front wheel drive vehicles have a differential built into the transmission case and share the fluid. Check your owner's manual to make sure you have the correct type of fluid/oil for your vehicle.

Differential/gear oil lubricates the ring gears and gears that transmit power from the propeller shaft to the wheel axles. Keeping the differential oil clean and changing it regularly is just as important as engine oil, yet it is often overlooked or overlooked.

Over time, if the oil goes bad or you develop a differential leak, metal will rub against metal and wear down the surfaces. This creates a lot of heat from friction, which weakens the gears and leads to failure, overheating, or fire. A professional mechanic will change and/or change the differential/transmission oil to keep your vehicle running as it was intended.

Because your differential/transmission oil can deteriorate over time and need to be replaced, you should be aware of the symptoms that indicate an oil change is needed.

Signs that the differential/transmission oil needs to be replaced and/or replaced include:

The oil is contaminated with substances or metal particles
Grinding sound when turning
Buzzing sounds because the gears are rubbing against each other due to low lubrication.
Vibrations while driving on the road

Differential/gear oil is extremely important to keep your vehicle running smoothly, so this part should be serviced.
