On don't think when you drain the oil, all of the oil in the engine comes out. There for when you poor in 5.25 qts you have filled it past it's capacity. Last time I changed my oil I made the same mistake, I was not paying attention and poured nearly all of the 5.25+ qts (AutoZone exclusive) of Mobile 1 into the engine. But it is a pretty good rule of thumb to do about 4.25-4.5 qts and then add as you need.
In your case, like me. I drained the oil and refilled.
