The Real Reason Your 2013–2025 GM Oil Life Monitor Hits 0%
Table of Contents
Why your GM oil life hits 0% at 7,500 miles
For model-year 2013–2025 GM cars and light/medium-duty trucks, except the Volt, GM’s service bulletin caps the GM oil life monitor at 7,500 miles from the last reset. It also reads 0% after one year, whatever the mileage. GM’s bulletin on how the monitor calculates (version 3, May 2024) explains it.
- 0% on a lightly driven truck: read the mechanism section.
- Unsure your model qualifies: use the table.
- Under warranty: read the message and recall sections.
- Decoding one percentage: see what each oil life percentage means.

What GM’s 7,500-mile cap actually does
GM’s bulletin says the monitor calculates remaining oil life from three pathways, and any one can take the display to 0%.
- Engine revolutions, adjusted for temperature.
- Miles since the last reset, capped at 7,500.
- Time, ending at one year.
Revolutions fall with each engine turn, faster when coolant runs cold or hot, and coolant above 260°F (126°C) sends the display to 0%. The time pathway reaches 0% after one year, regardless of revolutions or miles. GM says 7,500 miles occurs only in “perfect conditions”: the best case, not a promise.
🔍 Why It Happens: The mileage and time limits sit on top of the revolution count, so a lightly driven truck can still hit 0%.

The bulletin states no cap for model years 2010–2012 and lists nothing after 2025. For those years, rely on your owner’s manual.

What GM says to do when the message appears
When “Change Engine Oil Soon” shows, Chevrolet’s guidance on the message says service is needed as soon as possible, within the next 600 miles. The page states no model-year range, so confirm in your owner’s manual for your VIN.
The same page says to change the oil and filter at least once a year and reset the system. A dealer can reset it, or follow your owner’s manual; steps differ by model, so they aren’t listed here.
Recalls and warranty: what applies to the monitor
No recall or special coverage for the monitor itself appeared in NHTSA records reviewed October 9, 2026.
NHTSA recall 25V274 (GM N252494000) covers 2021–2024 Escalade, Escalade ESV, Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon and Yukon XL with the 6.2L V8 (L87). For engines that pass inspection, the remedy includes higher-viscosity oil, a new fill cap and a new oil filter, free of charge.
✅ Do This: Enter your VIN in NHTSA’s recall lookup.
The FTC’s consumer alert says an independent shop or you can do routine maintenance such as oil changes; keep records and receipts. See who may do your oil changes under warranty.
When GM says change oil before the monitor does
GM’s bulletin on fuel-diluted oil from short trips (18-NA-246, version 7, March 2022) covers 2.0L LTG Envision, Regal, ATS, CTS, Camaro, Equinox, Malibu, Traverse and Terrain models through MY2019. It links a rich-fuel code (P0172) to short trips; GM says owners who keep driving that way must change oil more often than the monitor indicates.
GM’s engineering information on the 2019 6.6L monitor concern, released April 9, 2019, covers 2019 Silverado and Sierra 2500/3500 trucks with the 6.6L (L5P). It blames a software anomaly and offers an interim interval: 7,500 miles, 300 engine hours or one year, whichever comes first. GM says it is not a recall; its current status.
A simple routine that works with the cap
- Find your vehicle in the table above.
- Change the oil and filter when “Change Engine Oil Soon” appears, or at one year, whichever comes first.
- Reset the monitor using your owner’s manual.
- Keep dated receipts.
Ford’s monitor follows its own rules; see the F-150 oil change interval guide and how often to change oil.
