Use 4-stroke outboard engine oil.
Special engine oil is the manufacturer approved by the test, can meet the requirements of the engine grade and quality of oil. Of course, there are also oil in the market that meet the requirements, but users need to be familiar with the performance of oil and careful identification, so it is recommended to use special oil.
Outboard machines are more prone to wear and tear due to their long-term exposure to water, especially salt water. So users in their choice of outboard machine to buy oil, must be careful to identify. There are two kinds of outboard, one is two stroke and the other is four stroke. A two-stroke oil is not the same as a four-stroke oil. The four-stroke oil is just for lubrication. Two-stroke oil is mixed with gasoline for combustion in addition to lubrication.
