Oil Analysis Tracker
Oil Analysis Tracker with structured readings per session — build the longitudinal trend record that single measurements can't provide.
One elevated sample means little; three rising samples mean a tear-down conversation — which is why a longitudinal record is the entire value.

About Oil Analysis Tracker
What separates owners who catch engine problems early from those who meet them at altitude is rarely equipment — it's records. Spectrometric oil analysis reads wear-metal trends (iron from cylinders/cam, copper from bushings, aluminium from pistons) — the TREND across samples matters far more than any single number. And the diagnostic punchline: one elevated sample means little; three rising samples mean a tear-down conversation — which is why a longitudinal record is the entire value. This tool is that record: structured fields, dated sessions, per-aircraft separation, CSV out. The trend does the diagnosing; the log just makes the trend visible.
How to use Oil Analysis Tracker
- 1Log the structured readings after each flight, sample or service event.
- 2Scan the table for drift against your own baseline before reacting to single values.
- 3Export the trend record for your mechanic, engine shop or analysis lab.
Why use Oil Analysis Tracker?
- ✓Identical structured fields every session — trends stay comparable
- ✓Per-aircraft/engine separation for multi-aircraft owners
- ✓12-month activity tile shows whether the record is staying alive
- ✓Captures the signal that matters: one elevated sample means little; three rising samples mean a tear-down conversation
- ✓CSV export turns maintenance conversations into data reviews
Frequently asked questions
What do rising wear metals in oil analysis actually indicate?+
Iron trends point at cylinders, cam and lifters; copper at bushings and thrust washers; aluminium at pistons; chrome at rings; nickel at valve guides. Labs flag deviations from both the engine model's norms and YOUR engine's baseline — the second being why a continuous record matters. A single high sample after a cylinder change is noise; a three-sample climb at steady utilisation is signal.
How often should these readings be logged to be useful?+
Often enough that the series outweighs the noise: every oil change for analysis-type records, every flight or weekly for monitor-derived numbers, every annual for inspection-type checks. The honest rule is consistency over frequency — six identical-format entries a year beat sporadic bursts, because trend reading depends on comparable conditions and unbroken sequence more than on raw volume.
Do I need an account or internet connection?+
No account and no connection are needed once the page has loaded — records live in local storage on your device and every calculation runs in your browser. Data doesn't sync between devices, so export the CSV when you want to move or archive your records.
What format does the export use and what reads it?+
A plain CSV with one row per entry and labelled column headers — the most portable format there is. Spreadsheets open it directly, most specialised software can map it on import, and a printed copy is perfectly legible to a human reviewer. Nothing proprietary means your engine condition record is never trapped here.
