Application
The main causes of damage in modern engines are abrasive wear, deposits and corrosion. Castrol CRB Plus 20W-40 with DuraShieldTM Boosters actively fights the main causes of engine damage to deliver superior protection by:
Preventing the agglomeration of soot as well as removing harmful soot particles from metal surfaces
Providing a protective film on the moving metal surface which resists break down even under difficult coditions, maintaining the film layer
Delivering improved deposit and corrosion protection by resisting thermal breakdown of the oil, and by neutralising harmful acids
Recommended by Castrol for use in all naturally aspirated and turbocharged diesel engines fitted in trucks, tractors, buses, goods carriers (LCVs), off-highway equipment, 3-wheelers and gensets.
Storage
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, exposed to hot sun or freezing conditions.
