Rubia Optima 3000 10W-40 is a synthetic technology lubricant particularly suitable for use in on-road heavy-duty diesel applications. With its "Low SAPS" (low sulphated ash, phosphorus and sulphur) technology, Rubia Optima 3000 10W-40 protects diesel engines equipped with post-treatment systems such as diesel particulate filters (DPFs).

This high-performance lubricant is approved by Volvo for its latest generation of Euro 6 engines with long oil drain intervals defined by the manufacturer. It is also recommended for several manufacturers, such as IVECO for Euro 5 (and previous) engine models.

Rubia Optima 3000 10W-40 enables the coverage of a fleet of mixed brands of engines (American and European manufacturers) with a minimal number of products.
