Are Fuel Additives Effective?
2 Answers
Fuel additives do have certain effects. Below is a relevant introduction to the functions of fuel additives: 1. Cleaning effect: The effect of this function is not immediate; its value can only be demonstrated through long-term use. Engines that use fuel additives over a long period will show significantly less carbon buildup. 2. Fuel saving: Additives also have a fuel-saving effect, though it is not very noticeable, with savings of only about 5%. The effect might be slightly more obvious for vehicles that frequently travel long distances. The quality of additives available on the market is hard to guarantee, and using inferior additives can be harmful rather than beneficial. It is best to purchase them from 4S stores, although the price may be higher, but at least you can hold them accountable if any issues arise.
Having driven for over a decade, I've tried quite a few fuel additives and found them quite practical. Those brands that clean injectors and combustion chambers make the engine start much smoother and reduce idle vibration after use. Older cars or those frequently used for short trips benefit particularly; my previous old car saved a major repair cost after using them. However, it's essential to choose well-known brands and avoid cheap, no-name products, as they might have the opposite effect. Price-wise, they cost a few dozen yuan per bottle, which is low when spread over monthly costs; in the long run, they improve fuel efficiency and save some money on fuel. Always follow the dosage instructions when using them, as excessive amounts can harm the engine. Overall, they're useful but don't expect miracles—just consider them as part of your maintenance routine. Adding them during significant weather changes shows noticeable effects. Consulting a mechanic before maintenance is even better to ensure safety.
