Does Fuel Additive Harm the Engine?

An appropriate amount of fuel additive does not harm the engine, but excessive use or inferior products can cause fatal damage to the engine, such as engine knocking or detonation. The role of fuel additive: Fuel additive is designed to address carbon deposits in the fuel system of fuel-injected vehicles, quickly restoring the engine to optimal working conditions. It also compensates for certain deficiencies in gasoline properties and imparts new beneficial characteristics, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Precautions when adding fuel additive: Currently, the common fuel tank capacity for small family cars on the market is 35-45L, for mid-sized cars around 55-75L, and for large or luxury cars around 75-100L. The standard specification for fuel additive is usually 60ML, which can be mixed with 30-60L of gasoline. Therefore, a typical family car usually requires 1-2 bottles of fuel additive per tank of fuel, with the exact amount depending on the specific conditions of the car.

I've been using fuel additives in my car for several years, and they actually don't harm the engine. Instead, they help clean carbon deposits from the fuel injectors and combustion chambers. When my old car used to shake during refueling, adding a bottle of fuel additive would immediately make it run smoother and even reduce fuel consumption slightly. The key is to choose reputable brands and avoid cheap, unknown ones. Overdosing is not advisable – one bottle per treatment is sufficient, as excessive use might cause sensor misjudgment or abnormal emissions. The dosage is clearly stated in the instructions, and strict adherence ensures safety. Engine designs already account for such additives with strong compatibility, and regular use can even prevent major overhauls, making it quite cost-effective.

When repairing cars, I often see many people asking about fuel additives. I must say they are generally safe, but misuse risks do exist. Inferior additives containing impurities may clog fuel injectors or damage oxygen sensors, while excessive use can make the fuel mixture too lean, causing engine shaking. Choose certified products and don't add them too frequently; once a month is sufficient for cleaning, saving money without harming the car. Engine health relies on maintenance – additives are good tools, but relying on them while neglecting regular maintenance can actually harm the vehicle. Simply check the label and buy genuine products to use them with peace of mind.

From a cost-performance perspective, fuel additives are harmless but not miraculous. I prioritize saving money for my daily commute and occasionally add a bottle for maintenance. My engine has never had issues, but the long-term effects aren't noticeable. The benefit is that it can clean carbon deposits and improve combustion efficiency without harming engine components, but don't expect significant fuel savings. You can add it yourself, just be careful not to overdo it; risks only come from inferior products or excessive use. Used reasonably, it's not costly. A durable engine lasting many years makes this small expense to protect major components worthwhile.
