Castrol Outboard 4T is a high performance lubricant that has been designed for all 4 stroke outboard engines from major Japanese and American manufacturers.
Its part synthetic formulation will provide the highest level of engine protection over the wide range of operating conditions typical of outboard engines, ranging from high speed cruising to extended periods at idle.
Advantages:
- Part Synthetic formulation for enhanced piston cleanliness and reduced oil consumption.
- Excellent low temperature wear control for effective valve train protection.
- High resistance to viscosity losses allowing a thick oil film over time, even in the presence of high levels of fuel dilution.
- Good anti-corrosion properties for safe protection during winter storage.
