Initial conditions.
1. A car without maintenance minder, that gets maintained at fixed intervals every 10k miles.
2. For some reason or another the oil hasn't been changed exactly at 10k intervals, maybe between 200 or 500 miles more every service.
3. Now those little differences have accumulated and now the OCI is "out of sync" by 4k miles.
So now the 80k mile oil change was performed at 84k, so it is kind of confusing and for an OCD person could be a problem that will prevent a good sleep at night.
So what would you do?
1. Carry on with the present course and just keep track of the oil changes with a spreadsheet or something like that.
2. Pull the trigger on a short service at 6k, so that the oil changes are in sync with the odometer, but effectively wasting some of the life of the oil, that again, for an OCD person could be problematic. Or
3. Split the difference in multiple services, like do two oil changes at 8k miles, that way appears to be less wasteful than the other, although it is the same.
I know, I had too much free time in my hands, but I had to ask.
