Technically, you don’t have to change the oil filter every time you change the oil, but it’s still a good idea.
The oil filter can remove the larger pollutants from the oil in the engine, and replace the oil at the same time to ensure the smooth operation of all parts. In view of the fact that changing the oil itself is very simple, but the filter is very complicated, so some people only consider replacing the former between services, but you want to know if the filter is not replaced if there is actually any meaning. Besides the oil filters, the Oil Catch Can are required only for direct injection engines, as these unlike other engines do not have fuel regularly cleaning the valves and are hence more likely to experience the formation of carbon deposits.
Different answers from different people
- It’s better to change the oil more frequently
a) If a car has an oil filter that is difficult to reach, it will often choose the latter, changing the filter every 24k kilometers and changing the oil every 12k kilometers.
Principle: Almost all automobile oil pumps are positive displacement and gear type. This means that the amount of oil reaching the inside of the engine is not affected by how dirty the filter is. Only “effort” is made by the pump to push the oil through it to change (and a bypass valve saves the engine and the pump in case of excess pressure), so you know your engine will have the oil flow it needs. In addition, in a perfectly working engine, the amount of dirt “caught or trapped” by the filter is very low and hardly affected by driving style. So there is no big problem, run it to the manufacturer specified in the “full term”.
On the other hand, the oil will indeed be “abandoned” by the old engine and sports driving (high piston blowing), so there is a clear advantage to changing the oil more frequently. If you want to be “completely scientific” on it, you can install a differential pressure sensor on your filter, and then send the oil to the laboratory every 3k kilometers to see what its wear pattern is.
- The other side of the argument is more correct: if you change the filter frequently, you do not need to change the oil.Now, the frequency is different, and the oil must be drained before removing the filter, but if it does not burn, there is no need to replace the high-quality oil. As we all know, some cars that use high-quality oil have previously recommended this.
- The oil left in the oil filter will not contaminate the new oil, otherwise every time you do an oil change, a complete engine flush is required to remove the dirty oil residue. If oil filters have not been installed for two cars over 180,000 miles, there is no problem.
- Drain and flush the filter when changing the oil. How about changing the oil every second as a good compromise? You can reuse the filter many times, and the old oil will pollute the new oil very little.
- It’s worthy to change the oil filter more frequently
2. How important is the oil filter, especially for old engines like oil “jumping”, the filter is significantly higher than the new engine, so a lower replacement interval is a good thing. The filter has to capture as much dirt as new, or less, so it is not a big problem to run the filter during the manufacturing specified life and use oil for half of its life. By the way, Honda says that the filter must be changed every time the engine oil is changed. Anyway, a filter is so cheap, there is no big reason not to change it every time the oil is changed.
b) It would be good if you plan to change the filter at the recommended interval and change the oil more frequently. Maybe, if changing the filter is so difficult, it’s worth going to the store to change it.
c) The oil filter must be replaced every time the oil is changed, which will increase the annual automatic maintenance cost. Therefore, it is a natural question to question whether the oil filter must be replaced every time the oil is changed. Getting a direct answer is never easy. Firstly, the questions about the oil replacement should be resolved.
d) You need to change the oil filter every time you change the oil. In fact, some longer-acting oils (such as Amsoil) recommend that you replace the filter at regular intervals without using the filter.
The filter is very important in the transaction plan. Although the oil can withstand longer intervals, once the filter is full of oil, it will begin to bypass the unfiltered oil directly back into the mixture. This ensures that your engine will not completely fail due to lack of fuel. This also means that you have all the dust and particles that can cause serious damage in the engine. By changing the oil filter every time the oil is changed, you have much less chance of this happening.
e) It is best to change every oil change because they are cheap and there is no good reason not to do so. If you use synthetic oil, the oil change interval will be longer (usually twice or longer), which means you will not change the filter frequently every mile.
f) I know that many people change filters every second. Of course, these companies will insist that you buy a lot from them, so they are not trustworthy. When I changed the oil filter, it looked clean, but I was sure I could not measure the oil filter clogging/usage. Honestly, it depends on you. Considering its low cost and inherent peace, it must be replaced every time the oil is changed. In your case: You can try to open the used one and see if it is clogged or has a lot of stickiness. If you are using modern synthetic engine oil and the replacement interval is very short, then I would consider skipping some replacement cycles, otherwise, it will be replaced every time the oil is changed.
g) If you want to maintain the correct service schedule, you can rest assured, reliable and resell, it is necessary. Changing the oil and filters are complementary.
Let’s look at it from another angle. Suppose you change the oil and filter at appropriate intervals, then perform other oil changes between them, and then skip the filter. In the past, I wanted to do this, but I like to use high-quality Castrol oil. In this case, it may be said that the filter cannot complete the lifetime service due to the short interval. You might think that changing the oil does play a role, and you do, but when there is still half a liter of old oil flowing through the half-plus filter, it is difficult to prove that the cost of the oil change is reasonable. of.
In short, when you consider the workload and cost of oil changes, there is no good reason to skip the filter. Buy filters online in advance,the cost is not high.
3. Keep the old filter, which contaminates the new oil, and there is already old oil in the old filter. The working ability of the old filter has been compromised. New oil needs a new filter.It is true that the oil filter must be replaced every time. Would rather replace the oil filter than replace the engine or overhaul it.
h) The job of an oil filter is to remove contaminants from the engine and retain some oil from the previous oil. Remember the oil in the filter? That is the worst oil in the entire system. This is the dirtiest and most degraded. The filter holds it tightly, waiting for the new batch to appear to contaminate it (“Here is new oil, please enjoy some abrasives I collected!”. Worse, dirty filters will stop filtering and be effective The ground is reduced to the dirty barrel, your clean clean oil is shaking. But is it really necessary to change every time the oil is changed? Think of the whole problem as an equivalent biological function. Regular oil and filter changes will directly extend the overall operating conditions of the engine.
To sum up, most people still recommend changing the filter every time the oil is changed, depending on the situation. Next, let us discuss the specific situation.
Why timely replacement of car oil is important
The entire process of changing car oil may take up to 30 minutes. Beginners usually take longer, but this is usually a simple process. Unfortunately, many car owners neglected to change the oil and postponed the task until they found a problem with the engine.
Changing the car oil is very important-period. Automotive experts often tell drivers and car owners that there are many reasons to change oil, including:
Maintain the lubrication of automobile engines
You already know that there are many moving parts under the hood of a car, such as pistons and valves. They all move at high speeds, thereby generating heat. You can imagine how fast the engine wears out without lubrication. Therefore, the oil must be changed regularly to maintain the correct lubrication of the car.
Engine oil will keep engine components cool
When the moving parts of the car are not lubricated, they will generate friction and convert it into heat. Use clean, appropriate amount of engine oil to prevent the engine from overheating.
Engine oil will help eliminate dirt and sludge in the engine
Over time, car engines may become dirty. If the dirt is not removed, it may cause corrosion and eventually cause engine death. In addition, if you change the car oil irregularly, the dust will decompose and become “sludge”. Routine oil and filter changes will remove these dirt particles, allowing the engine to run efficiently.
Regular oil changes help increase gasoline mileage
If the engine is not properly lubricated, the fuel consumption of the car will increase greatly. Therefore, it makes sense to have clean oil in your engine, which can increase gasoline mileage by up to 2%. Yes, this does not sound like a huge improvement, but over time, it will definitely bring a lot of savings. In fact, you can save nearly four liters of gasoline each year!
Oil change can extend the life of the car
Routine maintenance can make your car last longer-simple and clear. You want to keep dirty oil away from car parts, so you don’t have to work hard, which increases the risk of engine failure.
How to check when to change car oil
Changing the oil is troublesome, but it is a necessary task. The good news is that you don’t need to change the oil when you don’t need it. There are no strict rules when replacing old dirty oil. Certain factors determine when the oil should be changed, including:
Your driving style
The age of your car or engine itself
your location
However, many mechanics agree that car oil should be changed every 4,800 kilometers (3,000 miles). On the other hand, the car manufacturer recommends that you change the oil when you reach a distance of 8,000 kilometers (5,000 miles) or more. However, under normal circumstances, you need to check every three months. Ideally, you can replace the old oil and filter during this time to get the best results.
If you use synthetic oil, you can travel without changing 16,000 kilometers (10,000 miles). Although your engine can change the oil every 8000 kilometers, we recommend that you change the oil more frequently. This is especially useful if you have an older engine or are driving at high speed.
What does your oil filter do
Engine oil plays an important role in keeping the engine running. It lubricates engine components, thereby improving engine performance and life. But did you know that a clean oil filter is essential to this process?
The task of the oil filter is to remove grit, dirt and metal spots in the oil. If these particles are not filtered out, they will scratch and scrape the engine components and even clog the system, thereby shortening the service life of the engine and possibly leading to expensive maintenance costs. A well-functioning oil filter ensures that only clean oil comes into contact with the moving parts of the engine.
According to the standard procedure, the oil filter must be changed every time the vehicle is brought in for an oil change. In fact, in many automotive centers, oil replacement is included in the oil replacement price.
Oil filter replacement frequency
Back in the day when most drivers changed their oil every 3,000 miles or three months, and the engine was equipped with a quart-sized filter, some penny clamps only changed the filter every other oil change. Nowadays, as the filter becomes smaller and the oil change interval is getting farther and farther, the oil filter must be changed every time the oil is changed. with no exceptions. In addition, if the oil change interval used by the driver is extended to 7,500 miles or longer, the filter should be a high-quality, long-life oil filter.
If you consult the user manual that came with your car, you will most likely be told to change the oil filter somewhere between 9,000 and 16,000 kilometers. However, many mechanics and automotive experts recommend that you stay safe and change the oil filter every time you change the oil. In this way, you can complete both tasks immediately without risking damage to engine performance or damage to components.
In addition, in various situations, you need to replace the oil filter in advance, especially if you regularly tow heavy objects or in bad weather conditions, when driving on dirty roads or in stop-and-go traffic . In addition, if the inspection engine indicator lights on the dashboard, you should always bring the car into inspection. This may indicate accumulation of debris and dirt in the engine, or may indicate another urgent engine problem.
Do I need a new oil filter every time I change the oil?
When performing regular car maintenance, you may be inclined to choose a cheaper option, or ask if you really need to replace certain parts regularly as we told you. One of the questions we encountered at Sherwood Ford was: “Do I need a new oil filter every time I change the oil?”
Technically, you don’t have to change the oil filter every time you change the oil, but it’s still a good idea. The oil filter can remove the larger pollutants from the oil in the engine, and replace the oil at the same time to ensure the smooth operation of all parts. At Sherwood Ford near Edmonton AB, we always replace both at the same time.
Most likely, if you read the vehicle’s operating instructions carefully, the manufacturer recommends that you change the filter every 6,000-10,000 miles or every oil change. The technician who actually handles the oil change may suggest that you change the filter every time you change the oil.
The impartial mechanic said that the number and type of driving will affect the frequency of filter replacement. They believe that most drivers change the filter every 7,500 miles, but in extreme driving conditions, the filter should be replaced at 3,000 miles. Extreme driving conditions include:
Lots of stop-and-go traffic
If your vehicle often drives in extreme temperatures
If most of your driving is on muddy roads or dusty conditions
Towing heavy objects often
One thing everyone agrees on is that when replacing the oil filter, it’s better to spend a few dollars more, and replace it often instead of running out of it. When was the last time you changed the oil filter of your vehicle?
The frequency of replcement for different cars- examples:
1.Honda
Honda has been doing it for many years before using fully synthetic materials. Their filter (Honeywell) has a rated mileage of 10,000 miles, but they use synthetic materials. It is recommended to change it to 5k. Therefore, at 5k, you need to change the oil, at 10k, you need to change the oil and filter. This may be the largest experiment you may want to conduct.
2.Alfa Romeo
If you have Alfa Romeo (Alfa Romeo), it is recommended that you change the filter every 6000 kilometers and change the oil at the same time. If you want to drive on the road for a long time, you must start to properly maintain it. Only when you “cruise” it and change gears at 4-5000 RPM/gear. If you are driving in a city (usually using 2-3 gears), you can change the oil and filter once a year (12-15000 km). It is also recommended to replace other filters (fuel, air, pollen) every year.
The frequency of replcement for different oil:
When using Mobil 1 5W:50 oil, the filter was replaced twice, which doubled the fuel mileage.
If you plan to change the filter every time you change the oil, then the most common problem is: when I changed the oil, I forgot to change the oil filter. it is too late?
No. Just replace the filter normally. After installing the new filter, run the engine for a few minutes, then turn it off and wait a few minutes for the oil to settle in the oil tank. Check the oil level and makeup as necessary to make up for the oil removed with the old filter. Remember, the oil is in the oil pan. It will not deplete the filter housing or mounting frame.
