Chapter and section verified against FAA-H-8083-32B, 2023 edition, on 28 August 2026. Page numbers are deliberately not cited: they move between printings, and a citation that rots silently is worse than a coarser one that stays true.

Elements The ACS asks for Where in FAA-H-8083-32B Read it for
K1, R1, S2, S4 Oil types, grades and uses; mixing oils; correct oil for an engine; oils by climate Ch. 6 — Functions of Engine Oil; Recommendations for Changing Oil Mineral against ashless dispersant, and break-in. PP-G Concepts §3
K2–K4, S8, S10 System operation and components; wet-sump; dry-sump Ch. 6 — Wet-Sump Lubrication System Operation; Dry Sump Lubrication System Operation; Dry Sump Oil Systems; Oil Pump; Oil Tank; Pressure & Scavenge Oil Screens Where problems appear — PP-G Concepts §4
K5, S14 Chip detectors Ch. 6 — Magnetic Chip Detectors PP-G Concepts §1
