Valvoline™ R&O Oils contain top-tier ashless rust and oxidation inhibition (R&O) chemistry in a high paraffinic, high saturates base oil for use in both steam and gas turbines. It is also highly suitable for use in circulating and hydraulic systems where oils are used for long periods of time. In addition to the rust and oxidation inhibition, these oils also exhibit excellent water demulsibility and anti-foam characteristics.
