I have done all my oil changes..... for the past 50 years...
Every change has included the amount that the owners manual said was required, and nearly every vehicle has shown about 1/4qt over full for the next several dipstick checks. Maybe after 2,000 miles it would be down to "full".... perhaps a purposeful deception to mask small amounts of oil consumption??
I would not worry at all about a reading 1/2 qt over. They may have put in the exact amount that is recommended.
