Outboard Motor Oil

Whether you should be using synthetic or organic oil in for your outboard motor oil is really a matter of personal preference. Both will serve the engine well, and have their own strengths and weaknesses. Here are some of the differences between synthetic and organic motor oil:

Organic oil is extracted from crude oil during the refining process, and may maintain some impurities. Synthetic oil is artificially made from other compounds, and includes specially designed performance enhancing additives.

Synthetic oil has several advantages over regular, such as a high viscosity index, a higher flash point, lower pour point, and very low volatility. But, synthetic oil is more expensive and in more limited quantities than organic oil. Most agree that synthetic oil is a better choice, but not as many choose it because it can be three to four times pricier.
