When you’ve done a lot of work with boats, you start to get a feel for what are the best tools to work with. This can be anything from the physical tools required to do serious maintenance to something as simple as the motor oil used on the boat. I’ve definitely found a few favorites when it comes to the top brands in the motor oil industry.
I haven’t thought too hard about what specifically the best outboard motor oil might be though. I think what’s most important is that there’s a level of consistency. For instance, it is always best to use the oil that the engineers that designed your outboard motor had formulated especially for that particular motor.
