Your car's service schedule is published by the manufacturer, keyed to year, model and engine, and it is in the handbook. Modern oil intervals typically run 5,000 to 10,000 miles or 6 to 12 months, far longer than the old 3,000-mile rule of thumb, which belonged to conventional oils and older engine tolerances. Following a generic figure instead of yours either wastes money on early servicing or misses a model-specific item that generic guides never mention.
Typical modern intervals
| Service item | Typical modern interval |
|---|---|
| Synthetic oil and filter | 7,500–10,000 miles or 6–12 months |
| Tyre rotation | 5,000–8,000 miles |
| Cabin and engine air filters | 12,000–15,000 miles |
| Brake fluid | 2–3 years |
| Transmission fluid | 30,000–60,000 miles, varying widely by model and gearbox type |
Why 'every 3,000 miles' is outdated
The 3,000-mile rule dates from conventional oils and looser engine tolerances. Nearly every vehicle built in the past fifteen years runs synthetic or semi-synthetic oil to a manufacturer interval several times longer, and many use an oil-life monitor that adjusts the interval from actual operating conditions rather than a flat number. If your car has one, it is more accurate than any published figure, because it is watching your engine.
Where your real intervals are published
- The owner's handbook, maintenance schedule section — the primary source, and usually downloadable as a PDF from the manufacturer's owner portal if the paper copy is lost.
- The manufacturer's owner app or portal, which matches your VIN to the correct schedule automatically and is the fastest way to be sure of the engine variant.
- A franchised dealer's service department, who can print the schedule against your VIN. Independent garages often default to shorter, more conservative intervals, which is not wrong but is not the factory schedule either.
Intervals differ between engine options under the same model name. Matching the schedule to the engine, not just the badge, is the part generic advice always gets wrong.
Severe versus normal schedules
Most manufacturers publish two schedules. The 'severe' or 'special operating conditions' schedule applies to repeated short trips, extensive idling, towing, dusty roads or sustained extreme temperatures, and typically shortens intervals substantially. Short urban journeys are the most commonly overlooked qualifier — a great many owners on the normal schedule should be on the severe one.
Keeping your own record
Whatever the schedule says, the record is what proves you followed it. For each item, note what was done, the date, the odometer reading, and who did it. Work out the next due point both ways — date and mileage — and diarise the earlier one.
| Item | Last done at | Interval | Next due at |
|---|---|---|---|
| Oil and filter (synthetic) | 42,000 miles | 8,000 miles | 50,000 miles |
| Tyre rotation | 44,500 miles | 6,000 miles | 50,500 miles |
| Cabin air filter | 38,000 miles | 15,000 miles | 53,000 miles |
Servicing sooner than required wastes a modest amount of money. Missing a model-specific item — a transmission fluid change or a timing belt that generic guides never list — is the one that ends in a large bill and a declined warranty claim.
