I recently did an oil change in my 2013 g37x sedan with 65,000 km and mistakenly put in a synthetic 5w20 instead of the 5w30.
Would you guys suggest removing the oil and putting the recommended in or just leave it until the next change. Your advice would greatly be appreciated.

It’s perfectly fine. Leave it in there. The car will be fine .

If you live in the Northern hemisphere, you're okay now that fall has fell. Wouldn't recommend leaving it in during summer months or if you do track events, though.
