I have to admit; the first time that I went to purchase outboard motor oil, I was overwhelmed by the wealth of options that were available. Not only were there different brand names, but there were also a myriad of options within each brand. After staring blankly at the crowded shelf, I decided to seek some assistance. I told one of the staff at the store what type of boat I had and he was able to be of some assistance.
Now that I have a more thorough understanding of engines, I know what to look for in oil and other products. Economical oils were my M.O. back in those early days, but now that I have invested in a top-tier watercraft, I want to ensure its longevity. I look for oils that have a high viscosity and flash point, such as Evinrude XD 100.
