You really don't have any problems. I would go with option 2, keep your oil for the next change and take advantage of the discounts on other items.

If you think about it, most vehicles today get non-synthetic oil and they last forever.
However, for the next oil change, ask to speak to the service manager, explain your problem from this oil change and ask for a mechanic who can (and will) read.
