A quick course in Engine Flush

Using an engine flush is an important way to maintain the health and cleanliness of your engine.

So what is engine flush and how does it work?

Engine flushes are chemical additives designed to clean out sludge, carbon deposits and other contaminants that accumulate inside the engine over time.

Engine flush is added to the old engine oil. The engine is run at idle for 15-20 minutes ensuring the flush has time to circulate around the engine and helped to clean away harmful deposits.

This makes perfect sense because it is logical to remove as much contamination as possible before you refill the engine with the new clean oil.

Why does oil break down?

Engine oil breaks down due to the intense heat, pressure and contamination it is exposed to during it’s lifetime. Eventually, the oil will lose it’s ability to lubricate sufficiently and form deposits. It will oxidise or form sludge.

The introduction of fuel dilution, soot vapour and acids into the oil system also degrade the ability of the oil to protect the engine.

Although engine oils now contain additives, such as detergents, anti wear agents and antioxidants. These additives are eventually used up and it’s ability to protect against wear, corrosion and sludge formation are significantly reduced.

We must also consider that extended oil service periods has put a massive strain on the ability of the oil to do it’s job.

How do we prevent oil breakdown?

There are a number of things we can do to prevent oil breakdown and increase the life of the engines in our cars.

Use high quality oils; Modern synthetic oils resist heat and oxidation More effectively.
Change the oil more regularly; Although it is often a good idea to follow the recommendations of the manufacturers, it is often prudent to change the oil more regularly. We suggest changing the oil at at maximum of 10,000 miles, but 8000 would be better. Always change the oil filter during an oil change. It works hard to filter harmful contaminants.
Check the oil regularly; Low oil levels will create higher engine temperatures; more oxidation and less protection.
Consider using engine flush, a fuel additive and even an oil additive: Why? Because the the flush will provide a clean environment for the new oil. The fuel additive will reduce the amount of fuel based contamination and improve running efficiency and the oil additive will prolong and enhance the life of the oil. Reducing friction and wear.
