What are some of the advantages of using Mercury OptiMax oil? The obvious answer is that the oil was specifically designed for use with the high performing OptiMax outboard engine. To expand on the response: the elite OptiMax outboard puts more strain on lubricants than the average oil can handle.
Typical two-stroke engine oils cannot cope with the hotter operating temperatures and reduced oiling rates of DI engines. Mercury OptiMax oil has additives that give extra protection. In other words, if you want your OptiMax engine to run efficiently, then you need to use Mercury OptiMax oil.
