I never really realized how quickly my boat goes through oil until I started to take the boat out a lot more regularly. I have recently spent a great deal of time calculating out just how much oil I use in a year with my boat. With more great weather last year, I have discovered that I am using far more oil than I have ever used in the past.
Since I now know just about how much I will use in a good year for boating and fishing, I have determined how much I can buy earlier on in the season. I am able to save myself a lot of money by getting large amounts of Evinrude XD100 oil at once. Buying in bulk can really make a difference when it comes to calculating costs later.
