Comparing Prices for Mercury Outboard Oil

One of my friends recently decided to start looking into using brand name oil. For years, he has stayed with generic boat motor oil, because he thought that the price made it worth it. However, over the last several years, he has had to spend quite a large amount of money on outboard engine repairs, which he blames on the inferior oil that he has always used.

He still wants to find the lowest price possible for better oil, since at heart he is a very cheap person. He has recently been comparing the price of Mercury outboard oil online and in stores. He thinks that the best way to get a great deal on this oil might be to buy it in large quantities from the internet, since his local boat shop seems to be overcharging for the oil.
