This question involves additives and base oils for a finished, high temperature lubricant.

A combination of anti-oxidant(s) AO and anti-wear agents AW comprise about 2.5% of this finished lubricant.

The rest of the finished lubricant (about 97.5%) is base oil.


In your own words please answer the following questions:

Q1: What is the name of this finished lubricant?

Q2: what is the base oil?


This question is not open to Engineers, Chemists, Formulators, or Tribologists.


Swipes and YouTube dumps do not qualify as a valid answer. no-no

In this case, we are talking about temperatures 3 or more times higher than a transmission fluid would ever see.

Transmission fluids contain at least a 13% additive package, so a transmission fluid would have 87% base oils.

Some permutation of top end lube / injector cleaner / snake oil, because

It's 97.6% base oil, and, "they're mostly just kerosene anyway"

NO, not kerosene, because this is a lubricant for high temperature applications, seeing up to 600F in certain locations in the engine.


It has a pour point of -71F.

It has an Evaporation loss of 4% at 400F.

It has an Autoignition Temp of 760F.

Is this a COMMON fluid?!?!?!

My first guess....

Or maybe something very rare & exotic...
Like Castrol Brayco Micronic 889 MIL-PRF-87252C PAO fluid?

Common wrt what?

It is common in the Aviation industry.

And Inspecktor submits the correct answers and receives the BITOG virtual Coffee Mug with the Piston Cup Emblem.

Jet turbine oil may have the following specifications among many:

It has a pour point of -71F.

It has an Evaporation loss of 4% at 400F.

It has an Autoignition Temp of 760F.

A kinematic viscosity of ~ 5.3 [email protected]


The bearing cells in the High Pressure or "hot Section" of Jet turbine engines have to endure very high temperatures in operation and very cold temperatures for a re-start.

The only oils qualified for this extreme environment are specialized Polyol Esters or POE's, and contain a Multi-Function phosphporus component with specialized anti-oxidants.

Esters in Synthetic Lubricants

One of the latest developments in Jet Turbine oils is Mobil Jet 387.

Dang, and you wouldn't let me play! grin

Just to add a little more data:

The first ester based jet engine oils date back to 1953 and were based on a diester (Dioctyl Sebacate). POE based oils were introduced in 1963 (Mobil Jet ll) as a 2nd generation oil. We are now up to 4th generation oils.

Most of the current jet engine oils use a Pentaerythritol (PE) type POE base ester made from mono-basic fatty acids from C5 to C10, both linear and sometimes branched. The exception is Eastman 2380 witch is based on a blend of a Trimethylolpropane (TMP) ester and a Dipentaerythritol (DiPE) ester. The POE content runs from 93 to 96 percent.

Most use at least two amine type anti-oxidants to exploit synergies. For lower coking the anti-oxidants are alkylated, and the cleanest are oligomers of these alkylated amine AOs. AO content is typically 2-3%.

The anti-wear additive is almost exclusively Tricresyl Phosphate (TCP), but there is an EP version that also uses a small amount of an amine terminated partial acid phosphate. The TCP content runs from 2-3%

Other additives include a yellow metal inhibitor, a silicone type anti-foam, and sometimes a rust inhibitor. These additives are generally less than 0.2% each.

The fluids are at least as much if not more coolants than lubricants. The Air Force uses a lighter oil (3 cSt @ 100C) because of remote cold bases. Other armed forces and commercial airlines use a 5 cSt oil, and some turboprops use a 7.5 cSt oil to lubricate the reduction gears.

The oils contain no detergents, dispersants, or ZDDP, so they are not suitable for car engines!
