  • Synthetic oil that meets all major marine requirements.
Configuration: 4-Stroke Size: 1 GA, Case of 3
You know if it Valvoline you can rest assured it is a quality motor oil. I don’t buy oils because of brand, but I’m also not going to pay the crazy cost of OEM marine oils. After my first oil change I will send in an oil analysis to know exactly what my outboard motor is doing.
