Mobil DTE FM Series oils are high-performance lubricants designed to satisfy a wide range of multi-use equipment requirements in the food processing and packaging industry. Qualified as NSF H1 lubricants and compliant with FDA Title 21 CFR 178.3570 for incidental food contact, they are manufactured in ISO 22000 certified facilities in line with ISO 21469 hygiene principles. These tasteless, odourless, premium-quality oils are formulated with non-toxic NSF/FDA food-grade base oils and additives that provide good wear protection, excellent oxidation stability and rust protection. Mobil DTE FM 32 is the ISO VG 32 grade of the series, with a kinematic viscosity of 33.2 mm²/s at 40 °C and 5.5 mm²/s at 100 °C, a viscosity index of 106 and a pour point of -21 °C. Like the other grades, it is an excellent gear, bearing and circulating oil, also suitable for critical hydraulic components such as close-clearance servo-valves and high-accuracy NC machine tools, as well as compressors, vacuum pumps and air-line lubricators. Its naturally high viscosity index base oils and high FZG Gear Test rating (fail load stage 12+) demonstrate excellent protection against wear and scuffing, letting a single product cover gear, bearing, circulating and hydraulic applications across multi-metallurgy designs. Mobil DTE FM 32 holds NSF ISO 21469 certification and NSF H1 registration, as do the other grades of the series, and meets FDA 21 CFR 178.3570 requirements, offering excellent air separation, very good water separation and high-level corrosion protection to reduce inventory needs and the risk of product misapplication.
