What is Jet Oil II?
Mobil Jet Oil II is a high performance aircraft-type gas turbine lubricant formulated with a combination of a highly stable synthetic base fluid and a unique chemical additive package. The effective operating range of Mobil Jet Oil II is between -40ºC (-40 ºF) and 204 ºC (400ºF).
What kind of oil do jet engines use?
Mobil Jet Oil 254
Mobil Jet Oil 254 is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types used in commercial and military service. It is also suitable for aircraft-type gas turbine engines used in industrial or marine applications.

What is a jet oil?
Requirements for aviation lubricants (jet oils) are beyond the capabilities of petroleum-based oils, so synthetic lubricants were developed to meet these needs. Jet oils are required to operate at extreme temperatures, from -40 degrees Celsius to more than 250 C.
How often should aircraft oil be changed?
For the past 40 years, I’ve used nothing but single-weight Aeroshell W100 in my aircraft, and have enjoyed engine longevity that is nothing short of phenomenal.
Why do aircraft engines burn oil?
Air-cooled aircraft engines burn oil, thanks to their necessarily loose piston, piston ring, and cylinder wall tolerances, so ash-forming detergent additives are an aviation no-no (and why you don’t run auto oil in airplane engines).
How many hours does a jet engine last?
Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more. With most business jets accumulating less than 500 hours of flying time a year, the schedule for modern jet engine MRO operations averages about 12 years or more.
