I plan to add Bellhammer Seven, but should I add less oil for the activator? Or is it ok to leave it as it is?

If you are able to aim for the middle of the oil level when adding Bell Hammer Seven, we would appreciate it if you could subtract 330ml of Bell Hammer Seven from the amount of oil.
Also, there is no problem even if you add more oil than the H gauge by adding more than the H gauge to the oil level as it is.
