What are the functions of engine cleaners and protectants?
2 Answers
Cleaners and protectants serve different purposes: one removes dirt and contaminants for expulsion, while the other forms a protective film. However, both functions can be achieved by engine oil alone. One of the primary roles of engine oil is to clean the internal components of the engine, thereby reducing wear on various parts. Protecting the Engine: Engine cleaners primarily target sludge removal in the crankcase, whereas engine protectants enhance the oil's anti-wear properties and inhibit sludge formation. Consequently, manufacturers often bundle these two products for sale. The process involves adding the cleaner to old oil before an oil change for cleaning, draining the old oil, refilling with fresh oil, and finally adding the protectant to establish engine protection. Base Oils: Base oils are categorized into three types: mineral oil, semi-synthetic oil, and full synthetic oil.
I've been driving for over a decade and have used various engine cleaners, whose main function is to deeply remove carbon deposits, sludge, and impurities inside the engine. The cleaner washes away these contaminants through chemical decomposition, making the engine run more smoothly. Afterwards, adding a protective agent is like applying a protective film that reduces friction and wear on components, while also preventing corrosion and extending the engine's lifespan. In practical experience, fuel consumption decreases slightly, acceleration becomes more powerful, and noise is reduced. Using it regularly during oil changes is cost-effective. I perform maintenance every six months, and it feels like the car is as durable as new, saving a lot on repair costs. With long-term use, there are significantly fewer engine health issues.
