Petrovöll TURBINE Oil is a high-quality, inhibited zinc-free turbine oil formulated using premium quality, chemically stable, high VI base stocks, which are further enhanced by the addition of oxidation inhibitors. These inhibitors provide resistance to thermal degradation over long periods of time in the presence of entrained air and catalyzing metals. It exhibits good demulsibility, permitting water and other contaminants to readily separate from the oil in the system reservoir.
