Can oil additives damage engine

Alex by Alex

Expert answer:

0

Quick answer

Oil additives can damage an engine if misused, such as using the wrong formula, over-dosing, or mixing incompatible types. Otherwise, properly selected additives are generally safe.

Detailed answer

While many oil additives are designed to enhance lubrication and protect against wear, using an inappropriate additive or too much of it can cause issues. Over-thickening oil can lead to reduced flow and overheating, while some metal-based additives can foul emission components. Always choose an additive that is compatible with your oil type and engine requirements, and stick to the recommended dosage to avoid potential harm.
