Mobilube HD Plus is an extra high-performance gear lubricant formulated from select base oils and an advanced additive system. It can be used for on-highway light- and heavy-duty trucks, buses, vans and cars. It provides excellent chemical and thermal stability at elevated bulk oil temperatures, performs well at low temperatures, and has demonstrated good protection from rust resulting from water contamination and wet conditions.
