Alusol AU 58 Pail-5gl Semi-Synthetic Coolants

Castrol Alusol® AU 58 is a semi-synthetic fluid recommended for aluminum machining of automotive components. Castrol Alusol® AU 58 provides the performance of heavy duty soluble oils without the unpleasant shop environments and high usage rates of soluble oils. Castrol Alusol® AU 58 is chlorine-, phosphorous- and sulfur-free, yet its performance exceeds soluble oils which contain these extreme pressure additives.
