Should you recommend changing fluids based on the color or smell of the fluid?

Question

Yes, always.

No. Stick with the manufacturer's recommendations.

Only if the color is brown and the fluid smells burned.

Only if the fluid is red and smells sweet.

Answer 1

The best recommendation is: No. Stick with the manufacturer's recommendations.

While color and smell can provide some indications about a fluid's condition, they are not reliable enough to determine when to change fluids. It is important to follow the manufacturer's guidelines for fluid maintenance to ensure proper vehicle performance and longevity.
