Pressure Washer Pump Service Tracker
Forecast the next pump oil service for your pressure washer from hour-meter readings — hours left, days left and a calendar date.
With your numbers: 138 − 100 = 38 h since service; interval 50 h leaves 12 h ÷ 3 h/day = 4 days. Follow the OEM service schedule where it differs.
Field notes from maintenance practice
The pump's worst enemies never show on the meter: running dry for seconds scores plungers, bypass running beyond a minute or two cooks the packed water in the head, and winter freezing cracks manifolds. The 50 h oil rhythm here is necessary but not sufficient — pair it with the operating rules (gun open before trigger-lock breaks, antifreeze flush before frost) and a pump lasts years instead of seasons.
Meter by engine hours if the pump has no meter — and log every freeze event and dry-run incident as a note; they explain future failures better than hours do. Convert the forecast date into action: order filters/parts when the tool shows ~2 weeks remaining, and book the technician at one week. Usage-based scheduling beats calendar-based for any machine whose duty varies — a calendar plan over-services the lightly used unit and under-services the busy one.

About Pressure Washer Pump Service Tracker
This forecaster turns two hour-meter readings into a service plan for a pressure washer: enter the meter now, the meter at the last pump oil service, the interval, and average daily use — it returns hours remaining, days remaining and the calendar date to book the work. Triplex plunger pumps on commercial pressure washers take pump oil changes every 50 h (first at 25 h), and gas engine oil every 50–100 h — small sumps, hard life.

Frequently asked questions
What is the right pump oil service interval for a pressure washer?+
Triplex plunger pumps on commercial pressure washers take pump oil changes every 50 h (first at 25 h), and gas engine oil every 50–100 h — small sumps, hard life. Severe duty — dust, high ambient temperature, heavy loading, short cycles — typically halves the interval, and OEM schedules list separate 'severe service' columns. When in doubt, sample the fluid/condition at the standard interval once and let the result calibrate your real interval.
Pump oil looks milky at the 50 h change — what happened?+
Water intrusion past the low-pressure seals — the classic early-warning of seal/packing wear, or of pressure-washing the washer itself (forcing water past the crankcase vent). Change the oil, run 10 minutes, check again: still milky means reseal time (cheap kit, easy job on most triplex pumps) before the contaminated oil takes the bearings and crank. Catching it at routine changes is exactly why the small 50 h interval exists.
My usage varies a lot week to week — does the forecast still work?+
Yes — enter your average daily hours over the last month or two, and refresh the reading every week or two. The forecast date self-corrects as the meter advances. For strongly seasonal equipment, use the season's typical daily hours rather than the annual average.
Hour-meter PM or calendar PM — which should govern?+
Whichever comes first, as most OEM schedules state (e.g. '250 h or 6 months'). Oil oxidises and seals dry out with calendar time even on a parked machine, while wear tracks running hours. This tool handles the hours side; put the calendar limit in your diary as the backstop.
