When the next oil change is due
Enter today's odometer, the kilometers at the last oil change, and the interval you follow. You get the next due kilometers and how far you still have, or how far you are overdue.
The math is simple: last oil kilometers plus your interval equals the next due mark. Remaining distance is that mark minus today's odometer. Crossing zero means you are overdue on kilometers alone.
A status of coming up appears in the last 1,000 km of the interval so you can book before the light or the shop calendar gets tight. It is not a workshop order for your VIN.
When you do the job, write it in a maintenance log and set the next due from the invoice or the manual. This page does not become that reminder.
Your handbook, severe-use schedule, or the last invoice wins over a default 10,000 km gap. Time still matters for cars that barely move. Set a reminder in RPMBase from the date or kilometers you trust.
Questions
What interval should I type?ShowHide
Use the gap from your handbook or the last invoice. Severe use and some engines are shorter than 10,000 km. Do not copy a round number just because the field starts there.
What about months between oil changes?ShowHide
This form is kilometers only. If the car sits for months, follow the time limit in the manual even when the odometer looks fine. The service checklist can flag oil when you add months since the last change.
Can I use miles?ShowHide
Convert to kilometers once, then stay in one unit in your log. Mixing units is how due marks drift.
