How can I maintain the performance of my BMW Z4's turbocharger?

I recently purchased a BMW Z4 and I've noticed that the turbocharger seems to be underperforming. What can I do to improve its performance and prolong its lifespan?

Regularly clean and lubricate the turbocharger components to prevent build-up of debris and maintain smooth operation. You can use a high-quality synthetic oil for best results.

Avoid harsh driving habits and excessive revving, as this can put unnecessary strain on the turbocharger. Instead, try to maintain a steady and consistent speed on the highway.
