Each and every single day out of the year that they arrive for work, the mechanics who work in auto shops all across the country must be prepared to answer questions that are fielded to them by customers who know very, very little about when to change motor oil, where to change car engine oil, where to get an oil change, and which motor oil should I use. These mechanics must be prepared to answer these and other questions about bulk motor oil.
One of the most common questions about bulk motor oil that is fielded to these mechanics is also one of the most basic. Basically, many customers want to know what they can use bulk motor oil for. In these situations, the mechanics are more than happy to tell their customers that motor oil can perform a great many functions. For example, bulk motor oil can be used to help the engine of a car start; it can also be used to lubricate engine parts; it can be used to reduce friction; it can protect a car from rust and other forms of corrosion; it can keep engine parts clean; and it can minimize combustion chamber deposits.
Another one of the most common questions about bulk motor oil which is fielded to these mechanics concerns the materials that comprise bulk motor oil. When they are asked these questions, the mechanics like to tell their customers that bulk motor oil is made out of petroleum based and non petroleum synthesized chemical compounds. These compounds are ranked against the SAE viscosity grades, which are ranked from low to high viscosity. The rankings include: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. Regardless of what compounds compose it and what grade it is ranked at, all forms of bulk motor oil are highly flammable, so these mechanics warn their customers to keep their bulk motor oil away from open flames which might cause the oil to explode.
Another one of the most common questions about bulk motor oil that is fielded to these mechanics concerns how much motor oil one should place into his or her car. The simple truth is that the vast majority of car owners do not know how much money to place into their cars. When they encounter these customers, the mechanics like to warn these customers that placing too little oil in their cars might lead to extremely high oil temperatures; this is because the heat from the engine will be more concentrated. This excessive heat can damage the car.
Finally, mechanics like to tell their clients that vehicles around the world produced more than 4 billion gallons of used motor oil in 2009. That number is expected to rise over the course of the next decade.
