Just out of interest, what is the recommended interval in your car?
Most car these days have 12-20k service intervals, even my 1990s Toyota had 9k intervals.
If you're changing the oil every 6k then it probably doesn't matter if a bit is left anyway.

Recommended interval is 12,500 miles or 12 months.
My wife's Mini has condition based servicing and didn't get its first oil change until 36k miles. I would never leave an oil change that long. Oil and filters are relatively cheap, engine repairs are not.
