From a common vehicle/machine user Engine oil is something that we change on a scheduled basis. May it be after 3 months, after 3000 miles, 5000 miles or 7000 miles. We simply know this since we are often reminded by our trusted Automotive workshop. And yes, we get the schedule to get our Engine oil change, we pay the bill without really minding what is on the bill except when we are told that we need parts.
Let us break down the parts of an Oil grade to help us better understand what its purpose is on our engine. We normally see on our receipts after a change oil the numbers 0w20, 5w20, 10w30, 10w40, 15w40. All we know is they are the grade of the oil put in our engine. Let’s break it down further.
Take for example the oil grade/viscosity above. Basic info that we get is that, since your vehicle is new and is running on gas, we will use 0w20.
The oil grade is divided into 2 parts, first part would refer how quickly the engine will start. Part 2 of that would refer to the thickness of the oil when the engine has reached the usual temperature. The next question that pops to mind is that, why does it have to change over the years? Why does it increase to 5w20, 5w30, 10w30? The answer here is simple, the more you use your vehicle/machine, the more its internal parts gets worn out. Yes, even when you constantly change your oil it will still get worn out. It is part of the wear and tear process that happens when metals run into each other.
Why the increase in viscosity is needed? This is to ensure that the same pressure is maintained when you are using the vehicle/machine. If the pressure is not maintained this is when we start to feel that the vehicle is no longer running like new.
