Since I own a company where people can hire fishing guides and a boat to take them out for a day on the water, I have a lot of boats that I have to take good care of. I have a mechanic who specializes in boat motors that I am happy to have helping me whenever one of my boats has a problem. I always go to him when I have questions to ask about my boats.
He told me early on that I should make sure that I use good quality oil for my boat motors since this will help me avoid potential problems that would otherwise be likely to come up. I had to find a way to make premium oil more affordable, so I started to buy a Mercury Oil 55 gallon drum whenever I needed oil. Buying in bulk like this saves me a lot of money.
