Engine sludge is essentially an amalgamation of oxidised oil and pollutants which have settled on engine surfaces. It was first recognised as a major problem some time during the mid-90s. Thereafter, engine temperatures got hotter leading to faster breakdown of oil. Nowadays, more vehicle owners tend to neglect the cooling systems of their automobiles by using long lasting antifreeze.
In general, all types of synthetic and conventional oils have the ability of suspending contaminants over their life. However, they tend to lose this ability in course of time, allowing the pollutants to settle on engine parts and form sludge. Poor habits of oil change can also cause oxidation within the engine and make the sludge gelatinous, which may get transported and deposited on various internal parts by the oil itself.
There are several signs that can indicate presence of sludge within an engine. They include:
- Rough acceleration
- Poor mileage
- Substantial reduction in oil pressure
Sludge formation is usually a matter of great concern for vehicle owners due to two primary reasons:
The involved oxidation reduces the amount of oil available within the system for doing what it is supposed to.
The gel like sticky substance covers every engine component it comes into contact with and prevents heat from escaping. This, in turn, puts excessive mechanical stress on the internal components, including the cooling system and radiator. In such a situation, every stroke of the engine can cause damage to timing belt, gaskets and other parts.
After forming initially in the oil pan, valve cover area and top part of an engine, the sludge moves and blocks the siphon. This results in unwanted wear and tear and may even lead to disastrous engine failure.
The best thing that one can do in order to prevent formation of sludge is change the oil regularly within the time recommended in the owner’s manual – this generally means that a replacement is necessary after an automobile has been driven for about 11,000 kilometres. Alternatively, one may use a high performance engine oil treatment, popular variants of which are readily available in the market of Australia. The product can not only suspend the sludge and other types of deposit, but also reduce wear and tear and toxic exhaust emissions. A popular high performance engine oil treatment, trusted and used by countless Australian vehicle owners, is TOHO9000 . Besides dissolving sludge, varnish and carbon buildup, TOHO 9000 can clean an engine when it is active and offer a smooth ride.
