Is Engine Cleaner Necessary to Add?

[NorahMarie]

Engine cleaner is necessary to add and will not harm the engine. Here are the specific details: Regular Replacement: If the oil filter is clogged, it will obstruct the flow of lubricating oil, leading to poor engine lubrication, increased wear, and even bearing seizure. Regularly clean or replace it. Typically, it should be replaced every 8,000 km. In dry climates, this interval should be shortened to 5,000 km. Car Maintenance: During maintenance, it is essential to replace the "three filters": the fuel filter, air filter, oil filter, and the engine oil. Currently, most cars use gasoline as fuel, so the so-called fuel filter is actually the gasoline filter, abbreviated as "fuel filter." The role of the "fuel filter" is to filter out impurities generated during gasoline combustion.

I've been driving for many years and often perform vehicle maintenance myself. Regarding engine cleaners, they are not essential, but in certain situations, they are worth adding. If the engine shakes during operation or fuel consumption suddenly increases, it might be due to excessive carbon deposits; a cleaner can remove these deposits, ensuring more complete combustion, thereby improving performance and efficiency. I add a bottle roughly every 10,000 kilometers as preventive maintenance, making the car accelerate more smoothly and drive more comfortably. However, don't add it too frequently, as overuse could waste money or have minor effects on some sensitive components. Choosing a reliable brand is key—I buy them online or from auto repair shops, and the instructions provide the recommended dosage. In short, it's not a must-have for daily use, but as an occasional 'maintenance helper,' I recommend trying it when the car's condition is poor or at high mileage.

I've been a car enthusiast for over a decade. From my experience, engine cleaners aren't something you need to add every time, but they can be genuinely effective in certain situations. I remember once when my old off-roader suddenly lost power in the middle of nowhere - after adding a bottle of cleaner, it ran much smoother; it cleared out the carbon deposits, like giving the engine a bath. Nowadays with my new car well-maintained, I rarely use it, only as a preventive measure or when symptoms appear, similar to getting regular check-ups. Cleaners are affordable and easy to use - just add them to the fuel tank yourself and take the car for a highway run to let it work. But remember, it's not a cure-all - if there's a serious engine issue, you'll still need professional repair. My advice is to listen to your car's sounds - if something seems off, try adding cleaner once to see if it helps. Don't make it a routine, only use it when necessary.

I prioritize practical maintenance and pay attention to every little detail of my car. Engine cleaners are more like optional tools; they help prevent carbon buildup, especially when driving frequently in congested urban areas where deposits tend to accumulate. I add it every 8,000 kilometers to keep the internals clean and avoid minor issues escalating into major problems, such as preventing sluggish acceleration. The cleaning process is simple: just pour it directly into the fuel tank and drive as usual—low cost and saves a trip to the shop. However, new cars or those running smoothly may not need it; use it only when there's a risk or symptoms. I don’t consider it mandatory, but as part of smart maintenance, it can extend engine life and reduce unexpected repairs.
