Is it necessary to add gasoline additive?
2 Answers
Gasoline additive does not need to be added. Gasoline additive is a liquid that enables complete combustion of automobile gasoline, usually directly mixed with gasoline and added to the fuel tank for use. Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through fractional distillation, cracking, or pyrolysis, and can be used as fuel. It has a high octane rating and can be classified into 89, 90, 92, 93, 95, 97, and 98 based on the octane level. The characteristics of gasoline include: 1. Volatility; 2. Stability; 3. Anti-knock properties; 4. Corrosiveness; 5. Cleanliness. Gasoline can be categorized by its manufacturing process into: 1. Straight-run gasoline; 2. Thermal cracking gasoline; 3. Catalytic cracking gasoline; 4. Catalytic reforming gasoline.
This issue really resonates with me. As a long-time driver who has tried several fuel additives, I've found they mainly fall into three categories: cleaning, maintenance, and performance enhancement. For new cars within the first 20,000 kilometers, additives aren't really necessary because factory fuel already contains additive components. For older vehicles or those frequently driven in urban areas - especially when experiencing symptoms like sluggish acceleration or idle vibration - adding a cleaning-type additive every 5,000 kilometers can help. But don't believe those exaggerated claims about 20% fuel savings; in reality, a 3%-5% improvement is already good. Always choose reputable brands, as off-brand products might clog fuel injectors. From my experience, taking the car on a highway run after adding the treatment yields the best results, as it allows carbon deposits to fully burn off and be expelled.
