Which gasoline is better to pour: 92 or 95

Owners of cars with petrol engines are often interested in which gasoline is better, choosing between the brands of fuel sold at gas stations. Such a question is not rhetorical, but has a completely practical meaning. It is connected with the settings of the power unit, stable and predictable work of all adjacent systems, as well as with the financial question: pay more or not pay? We will understand the essence of the issue.

Theoretical part

The numbers shown in the labeling of fuel, indicate very specific indicators and represent the octane number. The higher it is, the more fuel can resist self-ignition during the compression stroke in the engine cylinders. This helps to reduce the likelihood of detonations in a running motor. Under the detonation refers to the accelerated uncontrolled combustion of the fuel mixture, in fact an explosion.

Gasoline selection

You need to know that the octane number is used only for gasoline, and for diesel grades of fuel "cetane number" participates in the characteristics.

The definition of cetane number is significantly different from the detection of the octane index.

Gasoline that is distributed through the retail network can now have a maximum octane rating - A 98. But in order to know that it is better to fill 92 or 95 with a specific car in the tank, you will need to get advice from the manufacturer.

Factory fuel recommendations

Car companies can recommend both a specific type of fuel and a range of acceptable values. You can find out this parameter in the instructions that come with the new car or get information on the manufacturer's website. Often, for quick access to such data on the inside of the gas tank cover the exact permitted figures for gasoline are indicated.

If it is necessary to choose one brand, then there will be a designation, for example, RON 92, and when a range is allowed, it will be RON +95 or RON 92-95.

Injection engines installed on cars are designed for a specific brand of fuel. Here the recommendations from the manufacturer will be unambiguous. Fulfilling such a requirement, the driver will protect the engine, fuel system, catalyst and extend its operational life of the entire car.

Modifications and manipulations with fuel

Additives may be used to change fuel parameters. With their help, it is possible to increase the octane number artificially. Traditionally, in our country additives are called all additives (legal and not so), mixed in technical fluids. Counterfeit products (often useless and sometimes harmful) discredited this term.

The difference between 95 gasoline and 92 is that the A92 brand is the most “pure” product is a delusion. Some unscrupulous sellers often get higher octane numbers due to chemical impurities, octane correctors. Prove the opposite is possible only when checked by laboratory.

The “octane number enlargers” filled the market do not always correspond to the declared characteristics.

Although judging by the application should increase power, reduce consumption and reduce the detonation properties of gasoline.

There are situations when a car cannot drive without additives. This happens when filling low-quality gasoline. This is determined by the reduction in power and the appearance of extraneous sounds from the engine compartment. At the same time, additives from a proven manufacturer can save the day.

Additives to Fuel

The main enemy of quality gasoline is the sulfur content.

It is capable of slowly eroding the fuel system as caries. But there are no additives on the market that reduce its level in gasoline. Therefore, pouring over the “rash” mix of “pseudo A95”, a motorist risks more than when refueling with a quality A92.

Marketing A95

Recently it is easy to meet a product with premium or eco prefixes at gas stations. They are offered at a higher price. It is justified by the presence of substances that help to clean the fuel system, as well as get an increased power of about 10%. It is hardly worth much to hope for the latter.

It is believed that additives that help clean the injector and valve from carbon, behave too aggressively and lead to rapid wear of mechanisms and components.

In reality, the percentage of such additives is small. Therefore, fuel with these components can be periodically poured into the tank.

Maximum 98th

Gasoline with such octane number should be used only in sports engines. It is designed for high-tech power plants with a protective coating on the piston group.

It is used solely on the recommendation of the manufacturer or company that performed the tuning machine.

For cars that are not adapted to high-octane fuel, there may be disastrous consequences for the engine. When working with it, local overheating often occurs, reinforcing the deformation of the metal. Also more active burns through the valve. Unsupported candles ignite the mixture ahead of time, so the flame spreads faster than usual.

Basic security measures at gas stations

Refueling at stations with the logo of a popular brand is not always a guarantee for obtaining high-quality gasoline. Oil companies usually resell the franchise (the right to use the trademark) to small companies. Frequent cases of renting a small network of gas stations. And in the terms of the lease is not always prescribed lists of mandatory suppliers.

Visually distinguish leased stations from native, branded ones can sometimes by the presence of additional store chains on the refueling territory.

Also to help will be a virtual map indicating the points of branded gas stations. It can be found on the website of the oil company.

If there is a possibility, then it is necessary to limit to visiting only verified stations. This reduces the risk of low-quality fuel. At unknown points, it is desirable to fill only a limited minimum.

Conclusion

It is necessary to use the recommendations of the manufacturers of cars for refueling the desired type of fuel at proven gas stations. Periodic use of legal additives that clean fuel equipment is allowed.

Most foreign engines are adapted to the use of domestic A92.

It is not worthwhile to use fuel with an excessive octane rating to avoid engine damage.
