All oils are not created equal. When you’re shopping for new outboard motor oil, you’ll want to make sure it has extended drain capabilities in order to reduce your motor oil expenses. Other beneficial aspects of motor oil may be that it controls soot thickening and oxidation or that it is specifically designed for high-mileage motors.
You should also consider buying your motor oil in bulk. As with anything in life, buying in bulk can reduce the time and money you spend in shopping for motor oil. Especially if you’re a mechanic or own several vehicles with outboard motors, you’ll love the convenience that buying oil in bulk offers.
