Does Multi-Point Fuel Injection Require Fuel Additives?
3 Answers
Multi-point fuel injection engines do require fuel additives, as they can help remove carbon deposits, reduce fuel consumption, and restore engine power. Here are some precautions for using fuel additives: Use high-quality fuel additives: When using fuel additives, opt for high-quality ones. Premium fuel additives contain a large amount of cleaning and activating agents, which help eliminate gum deposits in the fuel and harmful substances like engine carbon buildup. Using inferior fuel additives may not only be ineffective but could also potentially degrade vehicle performance. Assess the need for fuel additives: New vehicles should not rush to use fuel additives; generally, cars with less than 10,000 kilometers are not suitable. If the vehicle does not yet have carbon deposits, fuel additives should be considered when there is a significant amount of black residue at the exhaust pipe outlet.
As a veteran driver with over a decade of experience, I find that using fuel additives in multi-point injection systems requires particular attention. This system injects fuel individually into each cylinder, and although it produces less carbon buildup than direct injection engines, the fine nozzles can still get clogged, affecting fuel consumption and power. With my weekly school runs stuck in traffic, carbon deposits accumulate rapidly. Recently, I've been regularly adding PEA-based fuel additives and have noticed significantly smoother cold starts. However, don't expect results from just one bottle—I follow the instructions and add it every few thousand kilometers. That well-known little red bottle works quite well; it wasn't until the third bottle that I clearly felt the throttle become lighter. Of course, brand-new cars in their first couple of years don’t need this expense at all.
From a mechanic's perspective, while multi-point fuel injection systems are more advanced than carburetors, fuel system cleaners are definitely not an IQ tax. Last time I disassembled an 80,000-kilometer car, the intake manifold had brown gunk growing like moss inside. A reliable cleaning-type fuel additive can dissolve these deposits, especially for vehicles frequently driven on short trips. I recommend checking the spark plugs during maintenance - if the electrodes appear blackened, it indicates incomplete combustion, which is when fuel additives work best. When choosing products, pay attention to certification standards. The blue bottle I always keep at my counter has many repeat customers reporting reduced idle vibration.
