When I discovered that the cheaper oil that I had trusted to flow through my Yamaha outboard motor was actually creating clogs and buildup in the system, I knew that I needed to buy a new kind of oil right away. I took the time to make sure that the engine was cleaned out before looking for new oil. The price for that definitely wasn’t worth the money I’d saved on cheap oil.
I started to look for a kind of oil that I would be able to rely on since it was clear that the cheaper types of oil were not as reliable as I had thought. Even though I looked at many different brands initially, I ended up buying Yamaha outboard oil in the end. I decided that the manufacturer brand was one I was likely to be able to trust.
