The failure rate in the 2022 State Administration for Market Regulation spot inspection still reached 44%! Do you still use this kind of fuel treasure?

Qualified fuel treasure, 7 technical indicators are the key


Shock! The National Quality Supervision Bureau reported that up to 44% of the fuel products still failed to pass the sampling inspection!

Recently, the national supervision and spot inspection of vehicle-related product quality in 2022 was notified. Among the 91 batches of fuel treasure products produced by 91 companies in 19 provinces (autonomous regions and municipalities) in the circulation field, 40 batches of products were found to be unqualified and unqualified. The rate is 44.0%.

Random inspection of fuel treasure product items
Some production companies have failed to meet the standards for two consecutive years.

This spot inspection focused on 7 items including pour point, flash point (closed), sulfur content, chlorine content, rust prevention/rust degree, demulsibility and simulated intake valve deposit quality of automotive gasoline detergent. , unqualified items related to flash point (closed), sulfur content, chlorine content, rust resistance, demulsification and simulated intake valve deposit quality.

Among them, flash point (closed mouth) is a safety item, and 16 batches of products failed to pass this item. After analysis, the main reason for the unqualified flash point (closed mouth) is that the raw materials selected during the manufacturing process are unqualified, such as low boiling point organic matter.

It is worth noting that spot inspections of Fuel Treasure products for two consecutive years have shown that although the failure rate has dropped by 12.4 percentage points from 56.4% in 2021, the failure rate of Fuel Treasure products circulating on the market is still relatively high. There are even companies that have failed to pass random inspections for two consecutive years.

Qualified fuel treasure
7 technical indicators are key

Fuel Treasure is a compound gasoline additive with detergent, anti-emulsification and anti-rust properties that is added to vehicle gasoline to inhibit the formation of internal deposits in the fuel system. The GB19592-2019 national standard for automotive gasoline detergents covers 7 technical indicators including demulsification, chlorine content, flash point, pour point, sulfur content, rust prevention/rust degree, simulated intake valve deposit quality and pour point. There are clear requirements.

1. Simulate intake valve deposit quality

This item is the most important performance indicator of the Fuel Treasure and is the main indicator to measure the ability of the Fuel Treasure to clean carbon deposits. Unsatisfactory quality of simulated intake valve deposits means that the Fuel Treasure product has no cleaning power for carbon deposits or the cleaning power does not meet the standard. .

2. Demulsification performance

That is, anti-emulsification function. If the demulsification performance is not up to standard, it will easily cause the oil to emulsify and block the filter, resulting in poor oil supply and affecting the normal operation of the engine.

3. Anti-rust performance/corrosion degree

During the storage, transportation and use of gasoline, moisture will inevitably exist, causing corrosion to the vehicle's oil system. Fuel treasure is required to contain anti-rust ingredients, which can prevent vehicle fuel tanks, oil lines and engines from rusting, and is beneficial to vehicle maintenance.

4. Chlorine content

The presence of a very small amount of chlorine in gasoline will cause corrosion to the engine cylinder, piston, nozzle, exhaust valve and exhaust pipe in the high temperature environment after combustion. In order to prevent fuel additives from introducing chlorine into gasoline, it is necessary to control the detergent Medium chlorine content, which plays an important role in protecting the engine. National standards stipulate that the chlorine content in fuel oil should not exceed 10 mg/kg.

5. Sulfur content

The introduction of a very small amount of sulfur may cause substandard gasoline quality and easily cause poisoning and failure of the three-way catalytic converter. Therefore, it is necessary to limit the sulfur content of fuel oil added to gasoline. National standards stipulate that sulfur content should not exceed 50 mg/kg.

6. Flash point

In order to meet the safety requirements for transportation, daily storage and use of fuel oil, national standards stipulate that the closed flash point should not be lower than 60°C. If you buy a fuel bag with an unqualified flash point, putting it in your car may cause a fire hazard.

7. Pour point

The lower pour point is conducive to the use in most areas of the country, especially in severe cold areas, which require products with lower pour points. The national standard stipulates that the pour point of a fuel tank should not be higher than -20°C. If you buy a fuel tank with an unqualified pour point, it may fail to start or stall during driving in the severe cold winter.
At present, the quality of fuel treasure products on the market is uneven. A fuel tank with unqualified technical indicators will not only fail to remove carbon deposits, but may also bring negative effects and damage the vehicle. Therefore, when purchasing a fuel treasure, you must first choose a product that meets all the above seven technical indicators.

What are the mainstream categories of fuel treasures in the market?
Which one is better?

In terms of efficacy, the mainstream fuel treasures currently on the market can be divided into two types: gasoline detergents (ordinary fuel treasures) and gasoline detergent synergists (high-end fuel treasures): gasoline detergents contain detergents and dispersants, which can loosen carbon deposits. It removes, refines and wraps the sediments, disperses them into fine particles and suspends them in the oil. They are mixed with the oil and gas in the combustion chamber and then discharged and removed, which can restore the original performance of the engine.

In addition to detergent and dispersant, gasoline detergent synergist also contains catalytic combustion-supporting components with high chemical reaction activity. It generates a large number of free radicals during the fuel combustion process, triggering a chain of molecular chain reactions, optimizing the combustion process, promoting full combustion of the fuel, and improving Fuel combustion efficiency. It also contains anti-friction and anti-wear components, which can lubricate and clean the fuel nozzle and cylinder, and can improve engine performance.

Both have set cleaning efficiency indicators, but the gasoline detergent synergist also sets emission reduction, fuel saving and power performance indicators on this basis. In comparison, the effect is naturally more comprehensive and thorough. Car owners, if their demand is not high, just choose a qualified ordinary fuel treasure. If you also have needs in terms of power improvement and fuel saving, then gasoline detergent booster (High-end Fuel Treasure) is undoubtedly the best choice.
