The factory interval is 6,000 miles or 12 months. Either change it now with good oil, or leave it with the old oil. Don't bother putting temporary oil in, that's just a waste of time, money and effort.
If you change it now, it will last the year or 6000 miles. Which puts you right into cold season again.
If you leave it, 3000 miles is not enough to need an oil change unless those were extremely hard miles, Oil lasts a surprisingly long time.
Instead of spending money on oil, buy a battery tender.
Spend the effort on starting and running the engine for 5 minutes once a month
Use fuel stabilizer in a full tank of gas.
Rest easy that you're doing good by your bike.
