Engine additives are chemical compounds designed to enhance the performance, efficiency, or longevity of a vehicle's engine. They come in various forms, such as fuel additives, oil additives, or coolant additives, and claim to provide benefits like improved fuel economy, reduced emissions, better lubrication, or protection against wear and tear.
However, it's essential to approach these additives with caution and do thorough research before using them, as not all additives may deliver the promised benefits, and some could potentially harm your engine if used incorrectly or in excess. Always follow the manufacturer's recommendations and consult with automotive experts if you're unsure about using any specific additive.
