Oil and fluid changes are routine maintenance tasks that are necessary for the proper functioning and longevity of a vehicle. They involve replacing the old oil or fluid with new, clean, and appropriate fluids that are specific to the make and model of the vehicle.

Oil changes involve draining the old oil from the engine and replacing it with new, clean oil. This helps to remove dirt and debris that can build up in the oil and can cause damage to the engine over time. The oil filter is also typically changed during an oil change to ensure that the oil is as clean as possible.

Fluid changes involve replacing other fluids in the vehicle such as transmission fluid, brake fluid, power steering fluid, and coolant. These fluids can become contaminated over time and can cause damage to the vehicle if not replaced regularly.

It is important to follow the recommended maintenance schedule for your vehicle as outlined in the owner's manual to ensure that these tasks are done at the appropriate intervals. Failure to do so can result in costly repairs or even engine failure
