Discover why WD-40 is not recommended for engine use and the potential risks involved.

90 views

WD-40 is primarily a solvent and water-displacer, not a lubricant designed for engine components. Using it inside an engine can lead to inadequate lubrication, potentially causing damage to internal parts over time. While it’s great for loosening rusty bolts or protecting metal surfaces from moisture on the exterior of a vehicle, it's not suitable for internal engine use where specific motor oils or engine-specific lubricants are required for optimal performance and protection.
