The efficiency of the engine depends on the state of the fuel system of the car. The cleanliness of the system determines the characteristics of dynamics and speed. Also, the condition of the fuel system has a significant effect on fuel consumption.
Not everyone can see the malfunctions in time.
Specifications that decline over time do not particularly affect the quality of driving. But some time will pass, and various breakdowns may occur. This is a reflection of the situation with the fuel system of the machine. It is very important to know what is the frequency of replacing the fuel filter on a particular vehicle.
Indeed, in these very details the fuel is cleaned, which significantly increases the efficiency of the engine. Over time, filters do a worse job with the cleaning task.
Causes of Common Faults
Many car manufacturers seriously argue that a modern fuel cell can work out over the life of a car. However, in reality, such a result is simply impossible to achieve. If filters can work for so long, then only in a sterile laboratory. The quality of fuel that is supplied to gas stations in our country, frankly, is low. And there can be found various garbage, which is not the best way affects the fuel system. So, trash and dirt are the cause of all problems with the car.
What is the frequency of replacing the fuel filter?
On average, modern automakers recommend replacing filters every 30 thousand km. run. Many motorists, who came to this thanks to observations and experience, are guided by the same figure. A signal to change the filter is an engine that "troits" or stalls.
Naturally, it is not always so simple. And if you refuel at those gas stations that offer high-quality fuel, have a more accurate driving style, rarely drive on country roads, you can significantly increase the frequency of replacing the fuel filter. But this is how it happens quite rarely.
Three signs of a clogged fuel filter
You should change it if your power unit is not working as smoothly as the new one, if you notice a sharp drop in power, if the fuel consumption has increased significantly compared to the nominal at this time of the year.
If pollution is only at an early stage, then these problems will not be so pronounced. Novice drivers may experience certain difficulties, experienced drivers, of course, will notice all this on time.
If the degree of pollution has reached the maximum stage, the motor simply will not start.
And besides replacing the filters, the owner will have to flush the motor. If you miss this point, repairs can be very expensive.
Diesel engines
Replacing a diesel fuel filter is a big story in its own right. It is represented here by several components. So, there are coarse filter, fine filter, as well as a special separator. All these components of one large cleaning complex have various functions, but can be placed in a single building.
The function of the coarse filters is the purification of diesel fuel from fairly large impurities. And what is interesting, you will not find such in the fuel system of passenger cars, but on trucks and various agricultural vehicles they are.
Separator filters are used to purify fuel from water. This element is somewhat reminiscent of a sump. Here, the diesel goes up, and the water collects below, and then leaves through the drainage.
Fine parts are used to maximize the cleaning of the solarium from the smallest fraction. In most cases, this element is clogged.
Car enthusiasts claim that replacing the fuel filter on a diesel engine is much more common than on similar gasoline cars. And there is also an opinion that replacements are necessary in the winter.
Why in the winter?
And here is why. Water that accumulates in the separator freezes at low air temperatures.
This does not have the best effect on fuel flow. And instead of winter diesel intended for winter, they like to acquire summer compounds. And in this summer solarium at low temperatures, paraffin is released. He then clogs the filters.
Experienced car owners carry an extra spare part with them in the winter in order to quickly install a new one in case of a clogged old one.
Diesel love service
In order for the diesel engine to work at the peak of efficiency, it is recommended to perform filter replacement after 8-10 thousand km. Well, you also need to drain the settled mass from it. Perform replacement with a shorter frequency is not worth it. Clogged filters can create increased levels of flow resistance.
Hyundai
If you look in the passport of a car of this brand, then manufacturers recommend replacing elements every 60 thousand km. Maybe this is a real figure for Europe, but our realities noticeably reduce the frequency.
So, on Russian fuel, the Hyundai fuel filter is replaced every 30, or even 20 thousand km. If replacement with such gasoline was carried out according to the regulations, many cars of this Korean manufacturer would not have survived until the weekdays. Perhaps, somewhere really the filter is changed after 60 thousand, but this is not about our country.
If we talk about the Hyundai Solaris, then the figure of 60 thousand kilometers can be trusted, because the Koreans produce it in St. Petersburg and know firsthand the situation.
In this car, you need to remove the rear seat for replacement. Under which you can find the fuel module cover.
Underneath is a pump and filter. Replacing it with your own hands is very simple.
For diesel "Hyundai" the current figure is 10 thousand km. This is the fuel filter deadline.
Opel
This manufacturer is known for its quality and fairly hardy cars. In the lineup of models there are both cars with diesel engines and gasoline engines.
The passport data indicates that for elements that are not integrated into the fuel tank and are not integral with the gas pump, the Opel fuel filter is replaced every 30,000 - 45,000 km. This will save power units from increased wear.
In addition, water should be regularly drained from diesel filters, then everything will be fine with the engine, and the car will delight its owner for a long time.
Chevrolet
Cars of this manufacturer are very popular. Often, novice motorists ask questions about the frequency of replacing filters and other consumables. So, the manufacturer in the documentation for the cars indicates that the replacement of the Chevrolet fuel filter should be carried out at least every 25-30 thousand km. This figure is already much closer to our reality.
It is worth considering that when driving along dusty, country roads, you can clog the filter much faster than for 30 thousand km.
Timely replacement of filters will not only protect your engines from breakdowns, but also allow you to get great pleasure from driving a car.
Nissan
Fuel in its composition has many different heavy metals, additives and other impurities that can cause early wear of the unit or parts of the fuel system. The relevance of this element in the cars of the Japanese manufacturer is simply invaluable.
With high-quality fuel, the Nissan fuel filter can be replaced no more than once in two years of active use of the vehicle. But in practice, even if the Japanese recommend performing this operation after 40 thousand km., It is necessary to change the filter after 30 thousand. And this is the maximum in our realities.
Yes, there are 30 thousand, even this frequency is not so straightforward. This topic causes constant debate in automotive forums. This can be explained by the fact that if the manufacturer proposes to replace after 40 thousand, then after 5 thousand the efficiency and power of the engine drops sharply. This suggests that the filter is clogged disproportionately to car runs.
Professionals give recommendations, where the replacement is indicated every 10 thousand, since different cars clog differently.
How to determine what should be the frequency of replacing the fuel filter? The fuel system has a filter element. Dirt lingers on it. Between the pump and the filter, a vacuum is obtained, which increases with the level of pollution. Therefore, the replacement should be performed at the time of the appearance of this very discharge.
On Nissan models, there are special sensors for this. Professionals say that Nissan indicators have special indicators that help determine the level of pollution.
Kia
Everything here is similar to Hyundai. The replacement of the Kia fuel filter should also be carried out at intervals of 20-30 thousand kilometers. But you need to focus on how the car rides. If efficiency and dynamics have fallen, there should be a replacement.
"Toyota"
According to the manufacturer’s recommendation, the Toyota fuel filter should be replaced after every 80 thousand kilometers. The filter is located in the gas tank. To access it, you need to dismantle the rear seat cushion.
But such a huge figure is relevant only for the original filters.
Those that are sold with us rarely work out even 30 thousand. And our fuel makes the figure of 80 thousand simply unrealistic. Listen to your car, you will understand when the filter requires replacement.
Ford
The manufacturer recommends changing filters every 20 thousand mileage. This figure is closer to reality. Replacing the Ford fuel filter should be performed at each scheduled maintenance. In different cases with Mondeo and Fusion, it is recommended to replace them after 15 thousand.
Owners recommend observing an interval of 15 thousand km. This is the optimal frequency in our conditions.
