Engine sludge - the leading cause of fuel consumption

Many people wonder why used cars consume more gas than new cars. The reason, not everyone knows, comes from soot and dirt accumulated inside the engine.

Internal combustion engines use gasoline to create heat energy and generate power. Initially, the details such as the combustion chamber, injectors, carburetor, and intake valve of the motorcycle engine are shiny, most of the fuel is burned and produces work, making the engine highly efficient.

However, during use, carbon soot from burning gasoline and oil, combined with excess fuel, causes internal components to become clogged, leading to reduced efficiency.

Typically, users only start to care about engine sludge when the vehicle stalls, jerks, or won’t start. Few people notice the previous symptoms. By this time, engine power may have dropped by about 30%.

Among the causes of engine weakness, dirt is the main cause, because it will clog the fuel injector, exhaust valve, and air intake.

Normally, with a vehicle operating for about 5 years, users often need to overhaul the machine once. Mechanics will disassemble each mechanical part and clean it with gasoline as well as solvents. The cost for one disassembly is quite expensive and time-consuming.

Recently, a method recommended by engineers is to remove dirt with gasoline dilution. With this method, users only need to mix a 75 ml solution into a nearly empty gas tank, then fill it with gasoline.

During use, the solvent mixed with gasoline will clean the dirt inside the engine without having to disassemble the machine. The car needs to refill a bottle every 3,000 km to ensure the engine is always shiny.

Combustion chamber cleaner can be poured directly into the fuel tank.

The larger the engine capacity, the more solvent you need to add. According to Chevron Vietnam technicians, each 5-liter fuel tank should have one can of solvent added. For large displacement models with 15-20 liter fuel tanks, users need to add 3 to 4 bottles per cycle.

Referring to the current market, a bottle of engine cleaning solution for motorbikes costs about 60,000 VND. Popular brands include Caltex Techron Concentrate Plus for motorbikes, Yamalube Carbon Cleaner, Liqui-Moly 4T Shooter...

So on average, each year users only need to refill 3 bottles, costing 180,000 VND. In return, the car saves gas and maintains capacity. In addition, there is no need to add engine after 5 years of use.
