Is Engine Oil Additive Harmful to Cars?

[DeGrace]

Engine oil additive is not harmful to cars. Here are the specific functions of engine oil additive: 1. Substitute for engine oil: The engine has requirements for the amount of engine oil. Generally, after the engine operates normally and is turned off for 15 minutes, the oil level should be in the middle or slightly above the middle of the dipstick's upper and lower limits to be sufficient. If it is found that the engine oil is insufficient but there is no engine oil to replenish, engine oil additive can be added to make up the oil level. However, it should be noted that engine oil additive is a viscosity enhancer and cannot be used in large quantities or completely replace engine oil. 2. Improve oil burning: Engine oil additive can alleviate oil burning. Oil burning is mainly caused by the decreased sealing effect of the engine piston rings. Adding engine oil additive to increase the viscosity of the engine oil can make it less likely for the oil to enter the combustion chamber, thereby reducing the phenomenon of oil burning.

I used to be quite curious about oil additives and tried adding them to my car's engine oil, but the results weren't great. In fact, there was even an instance where it caused increased noise. Essentially, oil additives are supplements that claim to enhance lubrication or cleaning effects, but low-quality products can easily lead to sludge buildup, clogging oil passages or filters, and over time, may cause increased engine wear. I'd recommend avoiding the random use of such additives. Stick to branded original or certified engine oils, combined with regular oil changes and maintenance, which are sufficient for everyday driving. It's cost-effective and safe—why take unnecessary risks? If you're determined to try them, consult a technician first or opt for products with good reputations to avoid buying counterfeit items just to save a few bucks. In short, cars require careful maintenance—don't turn minor issues into major ones.

After years of car ownership, I believe engine oil additives should be handled with caution. While designed to enhance oil performance (e.g., anti-wear or cleaning properties), formulations that don't meet standards can disrupt the oil's chemical balance, reducing cooling efficiency or causing component corrosion. This is particularly risky for older models where compatibility issues may arise. For maintenance, I strongly recommend using high-quality full synthetic oils—cost-effective and reliable without needing additive supplements. If engine abnormalities occur, prioritize checking oil quality or worn components rather than indiscriminately using additives. Developing regular maintenance habits, like oil changes every 5,000 km, proves far more effective than relying on auxiliary products. Avoid unnecessary complications—safety always comes first.

From personal experience, oil additives do more harm than good to the engine. They may clog small passages, causing insufficient lubrication and accelerating component wear. I stick to standard oil for maintenance, which works better and is more worry-free. Regular inspections are the key.

I found that oil additives like oil enhancers are not necessary, and using them may even cause new problems, such as filter system blockages or seal aging. It's recommended to choose reliable engine oil and stick to simple maintenance.

Considering the potential hazards of oil additives, I prefer not to use them. Low-quality additives not only damage the engine but are also unfriendly to the environment, as chemical residues may cause pollution. It's wiser to stick with environmentally certified motor oils.
