ExxonMobil - Mobil Jet Oil II SDS EN
ExxonMobil - Mobil Jet Oil II SDS SRB

Mobil Jet™ Oil II was the first standard Type II oil on the market. After more than half a century, it continues to be the preferred oil of choice and is used in more than 50 percent of aircrafts in operation today.

This legendary, hassle-free, second-generation oil helps keep engines clean and operating at peak efficiency. Laboratory tests and engine inspections confirm it can handle extreme speeds, temperatures (up to 204 degrees Celsius/400 F) and stresses without breaking down.

Reasons to trust Mobil Jet Oil II

- It offers excellent deposit control, helping maintain engine cleanliness and reducing maintenance costs
- Provides superb elastomer compatibility, helping operators maximize component life and minimize oil consumption
- Offers exceptional wear performance, helping reduce component replacement costs and extend engine gear and bearing life
- Provides exceptional low-temperature fluidity and outstanding protection at high speeds
- It carries an extensive range of approvals, giving operators increased levels of flexibility

Features and benefits
Mobil Jet Oil II is formulated to meet the demanding requirements of aircraft-type gas turbines operating over a wide range of severe operating conditions. The product has a high specific heat in order to ensure good heat transfer from oil-cooled engine parts. In extensive laboratory testing and in-flight performance, Mobil Jet Oil II exhibits excellent bulk oil stability at temperatures up to 204ºC (400 ºF). The evaporation rate at these temperatures is low enough to prevent excessive loss of volume.

Key features and benefits include:

- Severe operating conditions
- Deposit control
- Foaming resistance
- Military use
- Wear protection
- Corrosion protection
- High/Low temperature viscosity

Applications
Mobil Jet Oil II is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types in commercial and military service. It is also recommended for aircraft-type gas turbine engines used in industrial or marine applications. Mobil Jet Oil II is approved against the Standard Performance (STD) classification of U.S. Military Specification MIL-PRF-23699. It is also compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699. However, mixing with other products is not recommended because the blend would result in some loss of the performance characteristics of Mobil Jet Oil II. Mobil Jet Oil II is compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and silicone seal materials.
