A boat or car trailer is designed to do a specific job and carry a load within certain parameters. In ideal conditions, the trailer and its component parts should last a long time with only scheduled maintenance, but if you use it extensively or may frequently carry particularly heavy weight, extra care is required. What can happen if you don't pay close attention to such a situation?

An internal combustion engine has many internal parts that need to move together to work correctly. These mechanical components are often in very close proximity to each other, and as they turn, oscillate or otherwise move, this can generate a lot of heat and friction. Clearly, your engine oil will need to perform well to avoid any issues and keep things moving like clockwork, but this lubricant will also need a helping hand.
