When it comes to changing oil, auto repair shop pinecrestshell.com explains that it depends on the age of the vehicle, the type, and the car owner’s driving habits. While most car manuals specify that the oil should be changed every 5,000 miles, modern cars are capable of driving 7,500 or even 10,000 miles before the next oil change.
The need for engine oil
The engine oil serves several purposes, and one is it’s the primary liquid cooling component. The oil rests at the bottom of the pan, just under the cams, pistons, and gears. When the shaft rotates, the various parts splash the oil to the sides and under the pistons.
Oil is a better coolant than water, and at the same time that it helps cool the chambers when the engine is running, it also lubricates the piston chamber walls as well as the other moving engine parts.
After the oil is splashed all around inside the engine, it trickles down to the pan, bringing with it any sediment from the combustion. This is an engine self-cleaning feature, which helps keep the chamber walls smooth. The dirt and sediment pass through the filter, continuously cleaning the oil.
This is where the driving habits of the car owner come in. When there is a lot of burned excess fuel due to the combustion chamber, more dirt and sediments accumulate in the engine. This results in an early breakdown in oil viscosity. The oil becomes sludge.
Ideal driving conditions
Driving habits are personal and differ from person to person. However, it is these habits that affect the engine health and the time between oil changes.
The ideal driving condition is that of driving on the highway, with engine temperatures reaching 100 degrees Celsius for at least half an hour. This will cause any water vapor inside the engine to evaporate. It will also be a vigorous exercise for the engine oil.
Frequent off-road driving or driving on dusty roads, excessive idling, or driving at low speeds for long distances is not healthy for the car. This would require an oil change every 5,000 miles or fewer.
