Where is power steering oil reservoir on 1988 Mercedes Benz 300E?
There seems to be a misconception in your question. The 1988 Mercedes Benz 300E does not have a power steering oil reservoir. The power steering system in this vehicle is a non-hydraulic rack-and-pinion system, which does not require hydraulic fluid or a reservoir. Instead, it relies on the engine's power through a belt to provide assisted steering.
