Synthetic Oils and Sports Cars

For the best protection, many high-end sports cars come filled with synthetic oil. “For most applications, stick with the manufacturer’s recommended oil. But if you want to better protect your engine over the long term, especially against extreme abuse like towing or constant stop-and-go-traffic, synthetic might be for you,” said Ron Sullivan, Penzoil’s technology manager, to “Popular Mechanics.”

What Sullivan said rings true for outboard motors, as well. Synthetic oils flow regardless of temperature, which helps with cranking in cold temperatures and flow in exceedingly hot temperatures. Synthetics might be right for you, but first start with what your manufacturer recommends, which is frequently Yamalube 2M.
