Considered an oil change pump to change your motor oil?
Oil has three important jobs to do inside your vehicle’s internal combustion engine. Its most important task is to lubricate moving parts. This means it stops them from coming into direct contact with each other and therefore from wearing each other out. A good example of this is the Pistons moving up and down in the cylinder head and of the bearings in the crankshaft. Without oil to act as these smooths cushion between the two pieces of metal they would damaged each other. Because of the heat and speed they operate at they can also be welded together and this is where the second property of oil, cooling, comes into play.
Oil is in contact with a very large surface area of the engine and this allows it to extract heat from the metal. When the oil is returned to the oil sump it is cooled by the flow of air underneath the car’s engine. The final property of oil, to clean, it is provided by additives in the oil. These are extra chemicals added to change the way the oil behaves. Cleaning agents and detergents are one example of additives. Others include changing the viscosity index so oil is thinner when it is cold and thicker when it is hot. Over time these additives become used up and this is why motor oil needs replacing.
The traditional way of changing motor oil is to get beneath the car and get your hands dirty but if you don’t fancy the sound of this you can use an oil change pump kit to pump the oil out of the engine using a tube inserted into dipstick hole. These simple devices are also known as engine oil extractors and can be purchased for around $60 from your local automotive store. One problem they cannot solve is changing your oil filter, you will still have to do this yourself.
