Engine flush – is it worth it?

by | Aug 20, 2021 | News

The debate about whether it is worth flushing the engine when changing the oil does not subside for a day. All this happens because it is absolutely unknown what age the oil is poured into the engine. After all, drivers often buy used cars and not new ones. And no one can answer the question: when was the last time the former owner changed the oil.

In which case you should definitely not flush the motor:

  • when it comes to a new car that one owner owned;
  • the first owner of the car always changes the oil in the engine on time;
  • there is confidence in the service on which the repair work is carried out;
  • during a long trip, the owner topped up the engine; it is not clear what.

If you purchased a used car and its service history is unknown, you should definitely think about flushing the engine. Unfortunately, every driver at least once in his life listened to the story that there are cases in which you could literally scoop deposits out of the engine with a shovel. To understand the condition of the engine, look into the oil filler neck.

What are the flushing options?

There are several ways to flush the motor. The simplest is a 5-minute flush, when, before changing the oil in the engine, a special fluid is poured into it. Then the engine runs at idle speed for several minutes, and only after that is it possible to fill in new oil and install the filter. There are flushes, with which you have to drive about a hundred kilometers, after which the oil is changed in the standard way. Flushing oil is commercially available. Already used oil is drained, poured in for flushing; after idling, it is drained, and fresh oil is poured.

If the oil is changed at a service center

In this case, it is best not to move far from your car until the end of the procedure. Only then can you be sure that new oil has been added to the engine. When the previous option for some reason is not possible, then immediately after the car is driven from the service station, you should check the oil level on the dipstick. It should be light in color and level with the top mark. To determine if the filter has been replaced, remove the splash shield and verify this. Even if you need to remove the engine protection, do not be lazy. Disassembly marks are also important.
