I've got over 100K DD miles on my 2011. I used Mobil 1 5w30 almost exclusively with a 5K mile OCI (couple times let it go over 6K). Never noticed the dipstick level drop much and certainly never had to add oil. No oil system modifications.
Those oil galley gaskets have me worried and are definitely a priority to replace before I get her out on the track. I purchased an oil pressure gauge also. If you plan to keep the car, that is definitely a good thing to have done. But the answer to your question is no, you should not expect oil consumption issues based on mileage.
