Why and when are we changing engine oil?
|New Oil Vs. Old Oil|
The first reason Due to user manual guide, automotive companies’ advice them customers to change oil periodically, by periodic kilometers or periodic time.
But, preferred to change the New Car oil's after the first 1000 Km, then period of 5000 km will be good for your car. but follow the company recommendations if available.
The second reason we change oil is engine repairing. Like insufficient burning or mixed oil with coolant water that’s cause oil property failure etc.
But to go in the depth, oil’s protects the engine parts from excess friction “engine wear”, and it also working as coolant for the moving mechanical parts. After a time period the properties of the oil will change due to working environments like viscosity which may be harmful for your Engine. The purity of the oil will affect the oil filter and/or the oil paths due to the material wearing rates. Both of them may be blocked and affecting the engine.
There are two types of changing oil for the engine, a- changing oil with changing the filter, b- changing the oil without the filter. the differences are the oil quantity and the cost. Change the oil with filter is better than keeping the old filter but not economical.
On the other hands,leakage or Oil evaporation is exists in some cases; this may require adding some new oil to reach the oil optimum level. But, in my opinion mixing the new one with the old oil could affect s the engine too.
In fact, changing the car oil refreshing the engine, increasing the engine efficiency, increases the durability of the “lubricated moving mechanical components” reduces the fuel consumption and gives your car the smooth and easy enhancement.
