The best things that the owner of a new car can do during the break-in period are:
Read the Owner’s Manual and the Maintenance Schedule completely, and don’t be ashamed to refer back to it periodically.
Lift the hood and do fluid checks every couple of weeks. It is not unusual for brand-new engines to consume a bit of oil in the very early stages of use, and–especially with a tiny engine that has very little oil capacity–it is important to keep the oil topped off.
In my experience, people obsess over whether to change their new car’s oil at 1k or 1.5k miles, but then totally forget about checking fluid levels–which, ultimately, is much more important than a quick first oil change.
Anyway, regarding oil change intervals, I agree with ok4450.
Rather than focusing strictly on odometer mileage, the OP should note the elapsed time interval for oil changes that is probably mentioned in the Maintenance Schedule. (For example, it may say something like, “every 7,500 miles or six months, whichever comes first”), and the elapsed time factor is just as important as the odometer mileage factor.
In this forum, we have encountered all-too-many people who drive their cars only in local, short-trip driving situations, and who accumulate mileage very slowly. They came to this forum after their engines were trashed, due to a build-up of oil sludge, and then we finally deduced that these people had decided to follow the mfr’s odometer mileage guideline for maintenance, rather than the elapsed time guideline. These folks thought that they were still able to do oil changes every…let’s say…10k miles, even though it took them 2 years to get to that point!
In reality, those short-trip, low mileage folks needed to use the Severe Service maintenance schedule that is listed–and almost always overlooked by car owners. Instead of going by odometer mileage, these folks should have been changing their oil at least every 6 months, regardless of how little odometer mileage they had accumulated during that time span.
Personally, I won’t go more than 5 months between oil changes, and I usually do them every 4 months, due to doing a lot of local driving now that I am retired. As one of the veterans of this board likes to say, “Oil is relatively cheap, and engines are very expensive”, and that is what I keep in mind when I err on the side of caution with my oil change intervals.
