Sprinter vans have unique power steering systems. This fluid meets the specific needs of those systems. It provides good lubrication for the pump and gear.

Mercedes-Benz Power Steering Fluid 345.0
This is the current genuine power steering fluid from Mercedes-Benz. You can’t go wrong with the official product.
It’s the fluid your dealer would use for a service. The 345.0 specification is what most newer Mercedes models need. It provides top protection for the sensitive steering parts.

Quicksilver fluid is mainly for boats and other marine uses. But some people use it in certain power steering systems.
This fluid fights water and moisture in the system. It works well in harsh marine conditions. The formula protects against rust and corrosion.
