[Maintain a car every day] It is all gasoline filter elements. Why is the replacement cycle five or six times different?

11 Hello everyone, this is a column focusing on car repair and maintenance. There are car secrets you don’t know here, and it will teach you how to avoid big pits on the road to car maintenance. I believe that not only you, but also many people have a certain hazy feeling about the automotive aftermarket. Here will help you uncover the unknown stories of car repair and maintenance.
There are many kinds of people in the world, and there are many kinds of cars. Many car owners will find a problem during maintenance. The gasoline filter elements of some models are replaced by 20,000 kilometers or even shorter. In some models, the gasoline filter elements are replaced by 100,000 yuan. Although both are gasoline filter elements, the replacement cycles are more than five times different. This issue of Xiaobian will take you to understand the difference between the two gasoline filter elements!
Gasoline filter elements are mainly divided into two types, built-in type and external type.
An external gasoline filter element
External gasoline filter means that the gasoline filter element is not placed in the fuel tank, but is generally located under the vehicle. Some models also design the gasoline filter element in the engine compartment.
When replacing the gasoline filter element, you can simply remove the gasoline filter element directly. The difficulty of replacing is very low. It only takes a few minutes to replace a gasoline filter element.
The external gasoline filter element is very simple in terms of institutional design, but it should be noted that the design of the gasoline filter element of each car is different. If it is replaced with an inappropriate one, it will cause insufficient fuel pressure and may cause engine shaking and fire.
The replacement cycle of general external gasoline filter elements is in the range of 10,000 kilometers to 20,000 kilometers. The main reason is that it is simple to replace, so the design life is relatively short.
2 Built-in gasoline filter element
The built-in gasoline filter elements are designed in the fuel tank, and the fuel tank is generally under the car, making it difficult to replace. Some models require the seat to be removed and replaced, while some models are very troublesome and require the entire fuel tank to be removed and replaced, which takes nearly an hour at the earliest.
The built-in gasoline filter element is integrated with the gasoline pump, which means that the oil directly coming out of the oil pump has already been filtered by the filter element.
The built-in gasoline filter element is designed to be invisible, so it is difficult to find out that this is a gasoline filter element under normal circumstances.
The replacement cycle of the built-in gasoline filter element is extremely long. Considering that its replacement is extremely inconvenient, engineers designed its service life to be extremely long, basically around 100,000 kilometers.
Many people don’t understand the replacement mileage of the two types of gasoline filter elements, and some even confuse the replacement cycles of the two types of gasoline filter elements. The external filter element takes 100,000 yuan to replace, and the built-in filter element takes 20,000 yuan to replace. It is a huge waste of money and can easily cause damage to the engine. Imagine replacing the external gasoline filter element 100,000 kilometers away, how dirty the filter element will be.

In fact, the specific replacement cycle of various parts of the car has been clearly stipulated in the instructions attached to the car, but most people only understand the instructions from a pile of paper. Be sure to get rid of this bad habit. Before using any product, you must read through the instructions. You must understand it first before you can use it better. Even cars are like this.
