Specifically formulated to provide longer catalyst component life, this fully synthetic 20w-40 engine oil also provides improved engine protection and maximum performance, said Mercury Marine.
The oil is not only factory recommended for emission controlled catalyst engines, it is also recommended for all MerCruiser petrol engines.
Catalysed marine engines have different lubrication requirements to other marine engines. The high phosphorous levels in some marine grade lubricants can badly damage catalyst systems, meaning that over time they will compromise the catalyst itself leading to premature failure and expensive replacement.
Mercury Marine said their MerCruiser 20w-40 engine oil has a specialised low phosphorous formulation, protecting the engine as a whole while ensuring longer catalyst component life.
The oil is a blend of three distinct synthetic base stocks. Mercury Marine said it provides both standard and catalytic marine engines with;
