A:
Jet A is the primary kerosene-based fuel used by CONUS
commercial airlines. It’s governed by ASTM D1655, the standard
specification for aviation turbine fuels. Jet A is similar to JP-8
except that it doesn’t contain the additive package required for
JP-8: static dissipater (SDA), fuel system icing-inhibitor (FSII), and
corrosion inhibitor/lubricity improver (CI/LI). The Army approved
Jet A, but only with the military additives that are in JP-8.
Q: What’s the main difference between JP-8 and Jet A fuel?
Q: So what should we call Jet A with military additives?
Q: Will I notice changes to installation facilities and vehicles?
Q: Does F-24 need to be tested more often?
A:
During a recent NATO fuels and lubricants working group
meeting, a new NATO code was issued for Jet A with military
additives: F-24.
Simply put, F-24 is Jet A plus the military additives S-1745
(FSII), S-1747 (CI/LI), and SDA. It has a slightly different freezing
point of -40°C compared to -47°C for JP-8.
A:
The main difference is cost. JP-8 and F-24 are completely interchangeable fuels for all
CONUS operations. TARDEC (ground), AMRDEC (aviation) and AMCOM have all approved
the conversion to F-24. For more information on aviation use of F-24, check out AMCOM

After logging in with your CAC, click the AGSE tab. Click Safety under the AGSE Browse
column, then Maintenance Information Message (MIM). Next, click on FY 2013. Finally,
click GEN-MIM-13-001 in the table on the top, center of the page.
In locations where arctic temperatures are expected, DLA-Energy will continue to
provide JP-8 to prevent fuel freezing problems.
Since JP-8 will remain the main fuel for OCONUS operations,
deployable tactical vehicles and equipment will keep their current
JP-8 markings. You may also see this marking on installation fixed
facilities and storage/distribution equipment:
JET FUEL
F-24
A:
F-24 may or may not be produced with an anti-oxidant. F-24 without an anti-oxidant
could degrade during long-term storage. The Army Petroleum Center (APC) will monitor
all product testing and stock rotation requirements. However, field testing requirements
will not change.

Q: What’s the
difference
between JP-8
and F-24?
Fuels…
Have
you
heard the
news?
The Defense Fuel
Supply Point (DFSP) in
Charleston, SC, was
recently converted
from JP-8 to Jet
A fuel with military
additives, also known
as F-24.
Ft Stewart and Hunter
Army Air Field, GA,
were the Army’s first
locations to use Jet
A fuel with military
additives. others will
be added as army
posts are converted.
The move is being
made as a
cost-
cutting measure.
With that in
mind, let’s take
a look at some
frequently asked
questions
about
the new fuel…
The cost of Jet
A fuel is
less
than
Jet A-1, which is
what JP-8 is typi-
cally based on.
Hey, you
heard
about this
new F-24
fuel?
Yep! And
I’ve got
a lot
of
questions
about it!
=
installation fixed facilities and
some equipment using F-24 will
bear new markings to reflect
F-24. However, units will maintain
accountability records as JP-8.
