It doesn't appear to be a problem for you. The vehicle I am using it in sees between 12,000 & 15,000 miles per year. I typically change the oil 3 times a year. I did my first full bottle application, next OCI I planned on adding 1 ounce/qt of oil. After reading your replies I might modify my plans slightly. Maybe now I will add 1 ounce/qt for the second OCI and then a full bottle for the third OCI. By that time there should be tons of info posted about the product.
