I think it is a good idea in general to not go over the top fill mark. After all some guy at Toyota’s was paid a good salary to consider all the issues affecting the engine wear, the oil seals, mpg , then decide where to put that mark, and he put it at that spot for a reason. Why ignore all that work he did? After all , when you wrote the check to buy your car, you paid him to do it.
I think there is a one quart difference between the low mark and the high mark, so you may be 1/2 quart overfilled. I guess what I’d do is drive it to the grocery store, do my shopping, and check it in the grocery store parking when I came out. Be sure to remove the dipstick, clean it, re-insert for 30 seconds, then pull it out carefully. Look at both sides of the dipstick. The correct reading is the lower of the two. If it remains 1/2 quart overfilled, ask your mechanic to drain 1/2 quart out.
