What oil does Lancer eat less 9. Engine ga4, an additive to reduce oil consumption

Inline motors Mitsubishi lancer 9 with 4 cylinders of 1.3 and 1.6 liters with one camshaft have power 82 and 92 Horse power accordingly, and the two-liter internal combustion engine, which is equipped with two camshafts, has a power of 135 horsepower. Difficult operating conditions for vehicles in our country significantly reduce the resource of these rather powerful units and, over time, lead to difficulties with increased oil consumption. More on this later in the article.

Increased consumption lubricant on a Mitsubishi Lancer 9 it can be very serious. If the engine consumes 1-3 liters of oil per 1000 km, you will have to renew the fluid all the time. Thus, over 10-15 thousand km, more than 15 liters of lubricant will pass through the system.

In the absence of leaking oil seals, seals and gaskets, the reasons for the increased consumption engine oil there may be the following:

Increased oil consumption due to engine valve oil seals and wear of the guide bushings

Valve oil seals in motors lose elasticity over time and when high mileage harden. On one engine, they can serve only 50 thousand kilometers, while on the other they have to be changed after 150 thousand kilometers. It is worth noting that in conditions of a high mileage of a car, replacing oil seals may not solve the problem with a high consumption of lubricant.

The valve stem seals can wear out when overheated, both internal (invisible) and visible, which is fixed by a temperature sensor. In the latter case, the problem lies in the failure of the cooling system, and in the first it is very difficult to diagnose the malfunction, although it is usually associated with poor fuel quality. With incomplete combustion of fuel, processed products form deposits and carbon deposits inside the combustion chamber, as a result of which the walls of the engine lose thermal conductivity, and also provoke overheating, which is not detected by the temperature sensor.

Replacement valve stem seals do it yourself without replacing the valve guides and troubleshooting may not give the necessary results and the Mitsubishi Lancer 9 engine will continue to consume oil. Considering the pumping effect that occurs when the oil seals are installed on worn guide bushings, the oil consumption may even increase.

Oil scraper rings, one of the reasons for an increase in oil consumption due to wear, ring sticking, coking, scuffing on the cylinder block

One of the main reasons for grease is the occurrence and loss of mobility of the oil scraper rings when the Mitsubishi Lancer 9 engine overheats. When using low-quality fuel, the rings coke and cease to function normally. In addition, when the coke clogs the grooves and the rings fall on it, friction will cause them to wear more actively against the cylinder walls.

Under conditions of mechanical wear, seizures appear on the liner, which also leads to increased consumption oils. Compression rings are also capable of creating a pumping effect in which the oil scraper rings become stuck and oil consumption increases. In this case, replacing the rings will not give a positive result if you do not squander the block under new size, and also do not micro-sand the surface. It should be said that wear in the block can change the geometry of the cylinder:

Taper.
Ellipticity.
Ovality.

This causes a knocking sound when the motor is running. It happens to be connecting rod as a result of oil starvation.

Poor quality fuels and other reasons that increase oil consumption

What can the fight to reduce toxic emissions and environmental friendliness lead to? Clearances must be optimized in the engine and its components. The smaller these gaps are, the faster they are clogged with products of improper combustion of fuel. As a result, high oil consumption begins, and manufacturers write about the need to use high-quality gasoline. The following reasons can aggravate the situation:

Operating the machine at reduced speed.
Use of unsuitable fuel.
Long idle work.
Driving with a cold engine.
Systematic trips over short distances.

The factors listed above prevent the motor from reaching the operating temperature at which coke and carbon deposits are burned. The use of AI-98 fuel instead of the 92nd also contributes to the formation of carbon deposits, since high-octane fuel has a lower combustion rate. Anything that does not burn can form carbon deposits and clog the catalyst.

Engine ga4 oil consumption reduction additive

Increasing the viscosity of the lubricant or using other brands of oils usually does not give consistent results. Regular flushing of the system special fluids makes it possible to keep the engine clean before changing the oil. In the course of flushing the engine, the inner surfaces are cleaned of deposits and carbon deposits, and also make it possible to decoke the rings and give them the same mobility.

The use of a special cermet additive for the engine helps to restore the resource and protect against wear. For example, Engine GA4 fluid can be used, which is designed for four liters of oil and does not change the physical characteristics and chemical composition of the lubricant.

Pro tips on how to reduce oil consumption on the Lancer 9

To reduce oil consumption on the Mitsubishi Lancer 9, it is necessary to replace the valve seals, oil scraper rings and guide bushings, but it should be borne in mind that replacing these elements by yourself does not always give a positive result.

The Mitsubishi Lancer 9 car is one of the most popular models of the beginning of 2000. It is distinguished by reliability and comfort, attractive cost. Thanks to this, he managed to win the recognition of many motorists. But this car has its drawbacks. They consist primarily in the fact that at the border of 150 thousand km of run, he begins to eat oil. The amount of lubricant consumed depends on its quality, driving style, frequency of maintenance.

Possible causes of increased oil consumption

If you find that your Lancer 9 is eating oil in large quantities, then there may be several reasons for this:

How to fix the problem of increased oil consumption?

So, you found out that your Lancer 9 is eating oil, and what should be done in this case? First of all, it is necessary to get rid of malfunctions that lead to excessive consumption of oil. You can do this with your own hands, but it is still better to contact a service center that specializes in engine repair. Replacing the valve stem seals seems like a very simple job. But in fact, it has a large number of nuances that only specialists can know about. In order to carry out high-quality repairs, you will need a special tool that not every motorist will have to afford.

If replacement parts are required, it is better to opt for original parts. After all, the cost of replacing them is quite high. And the use of spare parts of poor quality can lead to the need for repeated replacement after a short period of time.

In addition to replacing the rings, experts also advise replacing the crankshaft oil seals, candles, cylinder head bolts. The latter are disposable, so they can break if reused, leading to new faults and additional costs.

Video: causes of increased oil consumption

Often, after the car has covered 100 thousand km, the owners of Mitsubishi Lancer 9 begin to notice that the car has begun to consume a significant amount of oil. In some cases, even Lancer 9 oil “zhor” occurs, when several liters of oil are consumed during the short-term operation of the car.

Causes of increased oil consumption

According to practice, the first reason is the failure or damage to the valve stem seals installed in the cylinder head, due to which they do not perform their functions, and oil seeps through the valves into the cylinders, where it burns.

Another reason for the increased oil consumption of Lancer 9 is severe wear or stuck oil scraper rings installed on the pistons. Stuck or worn rings are not able to remove oil from the cylinder surface, and it enters the combustion chamber.

Determining the cause of increased oil consumption

Initially, the cause of the increased oil consumption should be determined. Indirect evidence of oil entering the cylinders is the appearance of significant plaque formed on the candle skirt.

We recommend checking the condition of the valve stem seals by visual inspection only. Some car owners advise paying attention to the smoke of the exhaust and the presence of oil particles in it. But this method is not effective, since it will not give an exact answer, which requires replacement - caps or rings.

The state piston rings determined by measuring the compression in the cylinders. In their normal state, the compression should correspond to that specified in those. documentation. Only a slight drop is allowed due to the general wear of the cylinder-piston group. Also, when measuring, the compression in different cylinders should be the same, although a slight difference is allowed.

Having extensive experience in determining the cause of increased oil consumption, our specialists will quickly diagnose the engine and offer solutions to the problem.

Elimination of increased oil consumption

The operation to replace the valve stem seals is not difficult, but without certain skills and a special tool, it cannot be done correctly. Also at self-replacement caps may be incorrectly installed, which will lead to further increased oil consumption by the engine.

Replacing the oil scraper rings with a Lancer 9 is a technologically complex operation, since the engine is extensively disassembled: the cylinder head, sump, and piston group are removed. In some cases, a cylinder bore is needed to restore operability, which cannot be done in a garage.

In addition, all the necessary spare parts, both original production and analogs, are available. Entrust your car to professionals!

Yes, we wrote such a peculiar name in the title of the article. This topic is dedicated to fixing one of several possible problems related to the fact that Lancer "eats" butter... The elimination of this is the analysis of the Lancer 9 engine and the replacement of various parts. Well, let's start:

I'll tell you the background: the first urges came after that. when, when changing the oil, I was asked in the service "was there any oil there at all?" I change the oil every 10,000 runs and monitor its level. After changing the oil, I began to monitor the level more often and realized that, like Kamaz! After a short topping up of oil, I decided to change the rings with all that it implies. I called Sergey (Gear of War) for help for which a special THANKS to him!

In general, we drove the car into the garage and began to disassemble the Lancer 9 engine, first draining all the fluids, except for the brake and power steering (a). Next are the photos of the process:

Actually our patient is a pretty cute Lancer 9

We begin to disassemble the Lancer engine:

We remove all attachments and remove Lancer engine valve cover, we see this

Next, we unscrew the cylinder head bolts and remove the head, what we saw did not surprise us in principle, we saw in general what we expected, judge for yourself by the condition of the pistons and rings:

The valves were in quite normal condition:

Next, we take out one piston at a time, remove the old rings, and use them to clean off all carbon deposits from the pistons, while spraying Carb with it. Cleaner.
By the way, the earbuds were in excellent condition.
Here's what happened after replacing all the rings and installing all the pistons in place:

After replacing the rings, we begin to collect Lancer engine 9 back. Then I did not take a photo, tk. I fixed everything basic, and the assembly is already a matter of technology and those who work with them know how everything is assembled.

P.S. during these works, it is imperative to change the gaskets of the candle wells (when I took mine off, they were just oak and let oil through), the valve cover gasket must be replaced (the same story as with the candle wells), the candles were also not in the best condition.
Sea of emotions Thank you Seryoga again!
And by the way, now mine Lancer does not eat oil.
I hope my report will help someone!

P.S. Note from the editors of the site: as we can see, the process is quite laborious, so it is advisable not to disassemble the engine without knowledgeable people.
