Characteristics VNII NP-50-1-4u. TU 38.401-58-12-91

VNII NP-50-1-4U Aviation Synthetic Oil is a high-quality diester aircraft oil with additive compounds mainly used for military equipment. This aviation oil is perfect for turbojet engines and has a temperature range of -60°C to 200°C with an overheat limit of 225°C. It is a highly efficient aircraft oil approved to use for all types of gas-turbine engines and aircraft turbofans. It does not require the replacement of construction materials or rubber parts, and is perfectly compatible with VNII NP 50-1-4F and all its equivalent.

VNII NP-50-1-4U Aviation Synthetic Oil is an improved analog to VNII NP 50-1-4F, Mobil Turbo 319A-2 (MT 319A-2), Turbonycoil 210A (TN 210A), IPM-10, and AeroShell Turbine Oil 560.

It is highly recommended for scouting aircraft equipment such as: MiG-27, Mi-26 helicopter, An-72, MiG-23, and MiG-29; civil aircraft such as: Tu-204, Il-96-300, An-124 and An-74; and gas-turbine engines: Mikoyan (Mig), Ilyushin (Il), Tupolev (TU), Antonov (An), Sukhoi (Su), and Yakovlev (Yak). VNII NP-50-1-4U Aviation Synthetic Oil is also recommended for advanced machinery such as Mig-35, Mig-29OVT with RD-33/RD-93 turbofan engines, and Su-35 with 117S turbofan engines.
