1. Why do we need to change motor oil?

Over time, the motor oil will degrade and the oil filter will be clogged up with particles and by-products, which is why it's necessary to change both the motor oil and oil filter.

2. What if body parts deteriorate?

Body parts deformed by collisions or other accidents not only look bad, but eventually rust as well, causing the strength of the body to deteriorate.

3. What happens when shock absorbers deteriorate?

When shock absorbers deteriorate, you will notice a bumpier drive than usual and have less control on your steering. Your tyres may even wear out sooner.
