Who wouldn't want to have a car in the best condition? Surely all car owners desire that. The best condition of a car is not only obtained from regular maintenance. It can also be influenced by the fuel used.

Every type of car has a recommended fuel with the appropriate octane. You must choose the right octane fuel. If you intentionally downgrade the fuel specification, your car may experience various problems. The issues can occur in both the short term and the long term.

Here Are the Bad Effects of Downgrading Fuel Specification

There are many ways you can ensure your car is durable and comfortable to use. One way you can do this is by using fuel with the octane recommended by the manufacturer. Every octane number in your car can affect its performance.

You should know that fuel with a lower octane will ignite much more easily. As a result, the thrust in the combustion chamber can weaken. Always make sure to fill up with fuel that matches the recommendations for your car. It is better to avoid unsuitable fuel.

However, if you use a car with unsuitable fuel, the impact can cause the engine to lose power. Not only that, there are still many bad effects of downgrading fuel specifications over a certain period. Here are the bad effects that could happen to your car.

1. Short-Term Problems

A decrease in fuel specification in your car can have bad effects even in the short term. You might hear a rattling sound from the engine. This is one of the effects that occur when using fuel with downgraded specifications. 

Not only that, but you may also unconsciously find that your car's fuel consumption becomes more wasteful. Then the output power of the car's engine also starts to become suboptimal. If this happens, it can make your car's performance abnormal. You may also need maintenance that can be quite expensive if affected by this bad effect.

2. Long-Term Problems

The negative effects of a decrease in fuel specification can already be seen in the short term. What about in the long term? The negative effects can certainly become worse. Damage to the piston is one of the long-term impacts that may occur. In the worst-case scenario, the piston can develop holes.

Additionally, it can damage the car's engine, such as requiring an engine overhaul. Carbon deposits can also occur. Even the exhaust emissions become more polluting and can cause air pollution. Of course, if this happens, it will be very detrimental to you. It would be better if you do not downgrade the fuel specification in your car.

It is better to continue using fuel that has been adjusted by the manufacturer.
