That looks a wee bit sketchy. I would be less worried about the overfill and more worried about what changed the color of the dipstick. Out of curiosity, why did you decided to use Royal Purple instead of the Mobil 1 that Mitsubishi recommends? For every single "OMG RP oil is the shiz, I use it in all my Civics" person I hear, there are as many, if not more, saying it is nothing but crap. I have even seen some people go as far as listing Royal Purple in a MOD LIST
. I am left shaking my head every single time I hear someone say that RP is better in any way than Mobil 1, like RP has a better staff of material scientists and chemical engineers than ExxonMobile.
In any event, I would just keep an eye on your oil levels and pay close attention to your parking spot to check for leaks possibly caused by seal damage, but I think you will be fine.
