Does Engine Oil Additive Affect the Engine?

[McEleanor]

Engine oil additive does not affect the engine. Composition of Engine Oil Additive: Engine oil additive is an extreme pressure additive, mainly composed of sulfur, phosphorus, chlorine, and other substances. Under the influence of temperature and pressure, it reacts chemically with metal surfaces to form a protective film. This film has high strength, can withstand heavy loads, and resists wear, making it commonly used in gear oils. Engine Oil Additive Protects the Engine: It protects the engine, significantly reduces wear, prevents overheating, and extends the engine's lifespan. Engine Oil Additive Enhances Lubricant Performance: It improves the overall performance of lubricants, providing significant enhancements for both synthetic and mineral oils. Engine Oil Additive Boosts Power: It enhances engine power and fuel efficiency, making the engine run smoother and quieter. Cleaning Effect of Engine Oil: It cleans the engine and prevents carbon buildup.

Engine oil additives have multifaceted effects on the engine. I drive an older car myself and frequently take long-distance trips. Adding oil treatment can help clean internal carbon deposits, reduce engine noise, and minimize wear. However, improper usage, such as using inferior products or excessive amounts, may lead to sludge buildup, clogging the oil filter, disrupting oil circulation, and increasing fuel consumption. I recommend opting for reputable brands, checking compatibility with the current engine oil, and preferably adding it during oil changes without overdoing it. Additionally, some additives claim to extend oil life, but if the engine already has issues, such as bearing wear, they might mask real problems and delay necessary repairs. In summary, moderate use of oil treatments during daily driving can be beneficial, but indiscriminate addition can be harmful—careful decisions should be made based on the vehicle's condition.

I believe engine oil additives can have positive effects on engines when used appropriately. As someone with years of automotive repair experience, oil additives can enhance lubrication effectiveness, such as reducing piston ring wear, which is particularly beneficial during the break-in period of new engines. However, they also carry risks. For instance, some cheap additives contain corrosive components that can damage seals or cause unstable oil pressure over time, leading to more severe failures. I've handled customer cases where excessive use of additives thinned the oil, increasing the risk of engine overheating. It's best to add them only when recommended by the oil manufacturer and to regularly check the oil's quality and color. Moreover, additives are not a cure-all. If an engine already has oil leaks or abnormal noises, relying on additives might do more harm than good, and professional inspection should come first. Keep a simple mindset; there's no need to blindly believe in the magic of additives.

Oil additives can indeed affect engine performance. Having driven a taxi for many years, I've found that oil treatments can sometimes make the engine run smoother with noticeable noise reduction, especially during high-load driving. However, choosing the wrong brand or incompatible products may cause sediment buildup that clogs oil passages, or even shorten engine lifespan. I prefer adding small amounts during oil changes to avoid complications. The key is to check user reviews thoroughly and purchase certified products - never compromise quality for small savings. Routine maintenance matters more; don't expect additives to solve all problems.
