DA Form 5991-E handles one job: oil analysis request (ega). The official title is OIL ANALYSIS REQUEST (EGA). Download it below, fill it in, sign it, send it where your directive says. The edition on this page is 07/01/2026, status ACTIVE, running unknown page(s) with about unknown fields to complete.
G-4 is the proponent, AR 700-132, PAM 750-8 the prescribing authority. Read the directive only if something about your situation departs from the standard case. Otherwise the form is filled by the individual it describes, or by the records clerk keeping the file, and reviewed through the printed signature blocks.
The formats are PDF, and the choice comes down to keyboard or pen. Fillable pdf for typing — live fields, tab order, saved entries. Printable pdf for handwriting — same page, no interactive objects, print it blank. Content is identical; only entry method differs.
A standalone reader is the safe choice for fillable work. Browser viewers vary in whether entered data survives the session, and there is no warning when it does not; a one-field save test settles it in seconds.
Free, unregistered, unmodified. What arrives is what the publisher released.
Start at the top and get the header exactly right. Official spelling of the name, identification number, unit, date. Everything downstream finds the record through those entries; nothing else on the page has that consequence.
Tabbing beats clicking for coverage. The order was set at build time and tracks the page layout, so following it leaves no gaps. Boxes and buttons are clicked; where options are exclusive, one selection cancels another by design. Watch field width on long entries: one-line fields have no wrap, and what runs past the edge disappears in print though the screen still shows it. Move that text to remarks or a continuation. Never leave an inapplicable field empty — enter the nil mark, because a reviewer cannot distinguish a skipped question from a considered answer.
The signature closes the form and nothing precedes it. Draft status holds until it is applied, by hand or by an accepted electronic method. Countersignatures go in printed order, each dated at signing. Then one final read from the top, looking for the four recurring defects: empty mandatory fields, swapped digits in identification numbers, day-month inversion in dates, and residue from a reused file that goes forward as though intended.
The Privacy Act statement is read before the personal entries, not after. It gives the collection authority, the purpose, the routine uses and whether disclosure is mandatory or voluntary. Once filled, your copy is a personal record and gets stored and transmitted accordingly.
Routing follows AR 700-132, PAM 750-8 and nothing else — a named office, the unit administrative channel, or the individual's file, according to why the form was raised. Copy it before it leaves. Retention is fixed by the records schedule for the series, which local practice does not shorten or extend.
Look for associated forms by series and number. In the DA series, documents sharing a proponent or a governing directive tend to travel together, and anything referenced on the page normally submits alongside. Collect continuations, covers and transmittals in advance of sending.
A stored file goes stale silently. The proponent revises, a new edition date is published, and your copy says nothing about it — so compare the printed date against the edition in force before typing into it again. Completed submissions on an earlier edition are not reopened.
The files are copies of published Department of the Army forms. This site has no official connection, no authority to issue anything, and no basis for saying whether an office will accept a given submission. None of the text is legal advice. Real questions — entry, requirement, eligibility — belong with G-4 or the administrative office servicing your unit.
