Oil quantity remains the same for oil changes but yes there is more oil in the system because you fill the oil cooler when you install it. Whatever oil is in the cooler during oil changes stays there since there's no drain on the cooler. The oil cooler shouldn't change the OCI on the CBS since there's no change even for the 335.
