If you read any manual on changing your oil, it's going to tell you to let that thing drip for 15 to 30 minutes to clear out as much of the old oil as possible. Meanwhile, your average oil change place is advertising that they will have you in and out of there in 15 minutes from start to finish. Which means there's no way they're letting it drip the minimum of 15 minutes.

The soil change was so overdue. There is a difference between the service interval and abuse interval of oil. I definitely got into the abuse range on this occasion. I just didn't have the money for the oil and the filter.

And while you're taking care of your own oil change. Make sure to check your brake fluid engine coolant and washer fluid and top them off as necessary.

I was told by two different places that trying to change any of the other oils is more likely to cause a problem if there isn’t one to begin with.

There's likely vehicle model specific variability here though. I had a first gen Honda Civic Hybrid with the first gen CVT. When maintained engine-to-transmission power was glassy smooth. However the CVT fluid would "wear out" and create a sound/feeling described as "judder". The fix was to change out the CVT fluid more frequently that the book listed maintenance interval. It was annoying effective. A fluid swap would immediately return it to glassy smooth and silent power delivery.

Doing a slightly more frequent CVT change wouldn't normally bother me but fluid would only last 20k-25k miles before the judder would start to return (slight at first) and the CVT fluid was Honda specific available only from dealerships and it was expensive. It look slightly less than 4 quarts and was about $7/quart when I had the car. I just checked the price today and it costs $16/quart! So that would be a minimum of $64 for a single CVT fluid change on top of regular oil/filter changes.
