“Every 3,000 miles” has been wrong for about twenty years, but what replaced it is not one number either. Of the vehicles we list with a published interval, the largest single group has no mileage figure at all — the car works it out as you drive.
Here is how the intervals we carry actually break down:
| What the manufacturer publishes | Rows |
|---|---|
| Per GM Oil Life Monitor (max 12 months) | 326 |
| Per Ford Intelligent Oil-Life Monitor — up to 10,000 mi / 12 mo | 188 |
| 10,000 mi / 12 mo (fixed) | 156 |
| Per Oil Change Indicator — max 10,000 mi / 12 mo | 124 |
| Per BMW Condition Based Service — max 10,000 mi / 12 mo | 113 |
| 7,500 mi / 12 mo | 106 |
| 5,000 mi / 6 mo | 99 |
| Per Honda Maintenance Minder — no fixed mileage, max 12 mo | 68 |
What a monitor is actually counting
None of these systems has an oil sensor. They are algorithms, fed by the things that degrade oil: engine revolutions, coolant and oil temperature, the number of cold starts, time spent idling, load. A Silverado driven on long warm highway runs may reach 10,000 miles before the light comes on; the same truck doing short winter trips can ask at 4,000, and both answers are correct.
Honda’s Maintenance Minder goes furthest: 68 rows in our data have no published mileage figure at all, only a twelve-month backstop. The Accord tells you when, and that is the specification.
Two practical consequences:
- Reset it after every change. An unreset monitor is counting from the wrong date and will let the oil run long. Every manufacturer’s manual makes this a step in the procedure, not an optional extra.
- The twelve-month limit is real. A car driven 3,000 miles a year still needs an annual change. Oil degrades by contamination and condensation, not only by mileage.
The maximums still matter
A monitor’s number is a maximum, and manufacturers set it per model — not per brand and not per year. Two examples from our own checking:
- Mazda runs two schemes at the same time. The CX-30 has been on the 10,000-mile vehicle status monitor since 2020, while the CX-5 was still on the 7,500-mile flexible system as late as the 2025 book. Same brand, same showroom, different ceiling.
- Hyundai and Kia raised theirs mid-generation, from 7,500 to 8,000 miles from the 2023 model year. Forty rows here — twenty of each — carry both figures with the year the change happened, including the Hyundai Elantra and the Kia Telluride.
That is the argument for looking up your own model rather than a brand rule of thumb.
Severe service is not an exotic category
Every manufacturer publishes a second, shorter schedule, and the conditions that trigger it are ordinary:
- repeated short trips, especially in the cold, where the oil never fully warms;
- extended idling or low-speed running — delivery work, heavy traffic, a police or taxi duty cycle;
- dusty, muddy, gravel or salted roads;
- towing, roof loads, or sustained high ambient temperatures;
- mountain and uphill driving.
Read that list honestly. A car doing a four-mile commute in a cold climate is on the severe schedule, even though nothing about it feels severe. In our data the severe figure is most often 5,000 miles or 6 months, and on some engines it is shorter still — 3,750 miles on several, and 3,000 on some turbocharged applications, which run their oil hotter.
Where the manufacturer expects you to do something specific about it, we say so. Mazda, for instance, asks you to set the maintenance monitor to its fixed interval yourself if you drive in those conditions, because the indicator otherwise assumes normal use.
Filters and intervals are the same decision
Almost every manufacturer we list changes the filter with the oil, every time. That is worth saying because “change the oil, skip the filter” still circulates: a filter that has done one full interval is the dirtiest component in the system, and its bypass valve opening is what sends unfiltered oil around your engine.
So when you look up an interval on a vehicle page — a Ford Escape, a BMW 3 Series, a Lexus RX, a Nissan Altima or a GMC Sierra — you are looking up the filter interval too, along with the OEM part number and how much oil goes back in.
One last note on the numbers you will see here: we publish the manufacturer’s figure, with the model years each one covers. Where a manufacturer’s own books disagreed across years, we left the question visible on the page rather than averaging two answers into one that nobody published.
