5 reasons why it is necessary to flush your car engine

1. Clean off accumulated dirt

Driving habits of each person will affect the engine quite a lot. When the need to use the car mainly in the city for short distances, running at slow speed and often stopping at red lights, the lubricating oil will become sludge and accumulate in the engine over time. These contaminants will prevent the flow of oil into the nooks and crannies of the machine.

Engine flushing solution will remove these deposits, helping to keep the oil flow unblocked and every part of the engine lubricated.

2. Keep new oil clean

When draining old oil, most of the carbon deposits, metal dust and some of the oil will remain in the engine. Flushing them before replacing with new oil will ensure that these deposits do not continue to exist in the engine and contaminate the new oil. This is also the reason why mechanics often advise you to always perform an oil change along with an engine flush.

3. Clean any remaining oil filter residue

The oil filter will retain dirt as small as 25 microns (1/1000 of an inch). However, in the oil there are particles smaller than that and are not blocked, over time they will accumulate in the engine as "sludge" that hinders the operation of machine parts. Even when changing new oil, they cannot remove these dirt and you need to use engine cleaning solution.

4. Clean the mechanical parts

Too much dirt and sludge accumulated in the engine will stick to the mechanical parts, creating a “glue” layer that hinders the operation of these parts. Not only that, they also increase fuel consumption, the engine will corrode faster and you will have to spend more money on repairs.

By using a cleaning solution, components such as piston rings (elastic cast iron rings located on the piston grooves), intake valves, exhaust valves, springs, and crankshafts always maintain smooth operation. In addition, engine flushing also helps non-metal components such as heat-resistant rubber gaskets not to become hard or cracked over time.

5. Ensure machine durability

When you buy a used car, you will not know the driving habits of the previous owner as well as how often they maintain the car. Besides, if the car has been disassembled for repair, flushing will ensure that any remaining dirt in the engine is removed and give you more peace of mind during future use.

It is important to note that when the engine oil is not changed for a long time, the oil will definitely become lumpy and carbon soot will greatly affect the stability of the engine.
