The resource and efficiency of the internal combustion engine directly depend on the quality composition of the lubricant. A motor oil suitable for the parameters of the motor creates a strong protective film on its internal elements and contributes to long-term operation. This article describes the characteristics of the recommended engine oil for Mitsubishi Pajero.
Model 1995 release.
Petrol power units
According to the car manual for the Mitsubishi Pajero (4G64, 6G72, 6G74 engines), the manufacturer recommends using motor oils that correspond to the SG class or higher according to the API classification. The recommended viscosity of the lubricant is indicated in diagram 1.
Scheme 1. The relationship between the viscosity of the oil and the ambient temperature.
According to scheme 1, at extremely low temperatures, 5w-20 should be poured (from -10 0 C and less). For a temperature index of less than +10 0 C, 5w-30 is poured, and 5w-40 or 5w-50 is poured if the temperature conditions are below +20 0 C. For a mixture of 10w-30, the operating temperature range is limited (from -30 0 C to +40 0 C). All-weather lubricants 10w-40 and 10w-50 are poured if the thermometer is above -30 0 C. At -15 0 C (and above), lubricants 15w-40 or 15w-50 are used. If the temperature outside the car is above -10 0 C, use 20w-40 or 20w-50.
Diesel engines
Scheme 2. Recommended viscosity of engine oil, taking into account the temperature regime of the region in which the car will be operated.
According to scheme 2, for the summer, with a limited temperature range from 0 0 C to +40 0 C, SAE 30 is used. If the temperature is above -10 0 C, pour 20w-40, with a thermometer reading of -15 0 C and above, pour 15w-40. For engine fluid 10w-30, the operating temperature range is limited (from -20 0 С to +40 0 С). SAE 5w-40 motor oils are used at temperatures less than +20 0 C, and 5w-30 or 5w-50 lubricants are used under temperature conditions less than +10 0 C.
Refueling volumes
The volume of engine oil, taking into account the filling capacity of the oil filter and Mitsubishi Pajero oil cooler, is:
- 4.9 l for motors 4G64, 6G72, 6G74;
- 6.7 liters in the case of 4D56 auto engines;
- 7.8 liters for 4M40 power units.
The total amount of oil required, excluding lubrication in the oil filter (without filter replacement) and oil cooler, is:
- 4.5 liters for the 4G64 engine;
- 4.3 liters if power units 6G72 or 6G74;
- 5.5 liters in the case of 4D56 and 4M40 motors.

Model 2001 release.
Gasoline motors
The Mitsubishi Pajero operating instructions (6G7 package) indicate that the lubricants used must meet the SG motor oil class (or higher) in accordance with API standards. The selection of the viscosity of the motor fluid is carried out according to scheme 3.
Scheme 3. Recommended viscosity of motor fluid.
Having deciphered scheme 3, it is not difficult to determine that at extremely low temperatures for the winter it is recommended to use SAE 5w-30 or 5w-40. In limited temperature conditions from -25 0 C to +40 0 C, mixtures of 10w-30 work. With a thermometer reading above -25 0 С, 10w-40 or 10w-50 is applicable, with a temperature reading of -15 0 С (and above), lubricants 15w-40 or 15w-50 are used. For regions with air temperatures from -10 0 С (and higher), 20w-40 or 20w-50 is poured.
Diesel car engines
The recommended engine oil for Mitsubishi Pajero (4D5 or 4M4 configurations) must meet the parameters of the CD blend class (or higher) according to API standards. The viscosity characteristics of the motor oil are selected according to scheme 4.
Scheme 4. Recommended viscosity characteristics of lubricants.
According to scheme 4, the manufacturer, depending on the temperature outside the car, it is recommended to use the following motor oils:
- SAE 30 if the thermometer reading is from 0 0 С to +40 0 С;
- 20w-40 under temperature conditions from -10 0 C (and above);
- 15w-40 at temperatures from -15 0 C (and above);
- 10w-30 at a temperature index from -15 0 С to +40 0 С;
- 5w-30 if the air temperature is from +10 0 С (and below).
Refueling volumes
Filling capacities of Mitsubishi Pajero including oil filter and oil cooler:
- total volume 4.6 l (0.3 l in oil filter) for model 6G7;
- total volume 6.5 l (0.8 l in the oil filter and 0.4 l in the oil cooler) for the 4D5 configuration;

Scheme 5. The influence of ambient temperature on the choice of oil viscosity.
Please note that motor fluids 0w-30, 5w-30 and 5w-40 can only be used if they meet ACEA A3 / B3, A3 / B4 or A5 / B5 and API SG (or higher).
In accordance with scheme 5, at a temperature index of +40 0 С, 0w-30 or 5w-30 is poured. Under conditions from -35 0 C (or less) to +50 0 C (or more), 5w-40 is used. If the thermometer shows from -25 0 C to +40 0 C, pour 10w-30. At a temperature index greater than -25 0 C, pour 10w-40 or 10w-50. With a thermometer reading of -15 0 С (and higher), 15w-40 or 15w-50 is used, if the temperature is more than -10 0 С, 20w-40 or 20w-50 is poured.
Diesel engines
For machines equipped with a particulate filter, it is recommended to use lubricants that meet ACEA A1/B1, A3/B3, A3/B4 or A5/B5 or API CD (or higher).
If the car is equipped with a particulate filter, ACEA C1, C2 or C3 is used, as well as DL-1 according to API standards. Scheme 4 is used to select the viscosity.

The maximum consumption of motor fluid is 1 l / 1 thousand. km and depends on the operating conditions of the car.
Conclusion
In the instruction manual for a Mitsubishi Pajero car, the manufacturer indicates that the use of an unsuitable motor oil can harm the engine. It is also forbidden to use additional additives to the car oil.
When operating the machine in difficult conditions, the engine mixture quickly loses its original properties and requires more frequent replacement than specified by the regulations. When choosing alternative motor oils, consider the presence of tolerances on the container with lubricant, and when handling motor oil, you must adhere to the safety measures described in the car manual.
Viscosity and specifications
At the factory, the engine is filled with special high-quality multigrade oil, which is suitable for operation at any time of the year, with the exception of extremely cold climatic zones.
The engine can be topped up with oil of a different specification. The viscosity grade of the oil should be selected in accordance with the data on . If the air temperature is only briefly outside the temperature range shown in the figure, the oil should not be changed.
Gasoline engines
A - all-weather oils with increased anti-friction properties, specification VW 500 00.
B - all-weather oils, specification VW 501 01.
– all-weather oils, specification API–SF or SG.
Diesel engines
A - all-weather oils with enhanced anti-friction properties, VW 500 00 specification (for turbocharged diesel engines only mixed with VW 505 00 specification oil).
B - multigrade oils, specification VW 505 00 (for all diesel engines),
- All-weather oils, API-CD specification (for turbocharged diesel engines only in case of emergency for topping up).
– all-weather oils, specification VW 501 01 (for turbocharged diesel engines only mixed with oil specification VW 505 00).
The quality of motor oils
All-weather oils of specifications VW 501 01 and VW 505 00 are relatively inexpensive and have the following qualities:
– the possibility of year-round use in temperate climate zones;
– excellent cleaning properties;
– good lubricity at any temperature and engine loads;
– stability of initial properties for a long time.
All-weather oils with improved anti-friction properties according to the VW 500 00 specification, in addition, have additional advantages:
– possibility of use practically at any temperature of external air;
- low engine power losses due to friction;
– make it easier to start a cold engine even at very low temperatures.
Warnings
Seasonal oils, due to their specific viscosity-temperature properties, usually cannot be used all year round, so they should only be used in the appropriate climatic zones.
When using multigrade oils SAE 5W-30, it is necessary to avoid prolonged operation of the engine at high speed and constant heavy load on the engine. These restrictions do not apply to multigrade oils with improved antifriction properties.
Additives for motor oils
Additives that reduce friction losses should not be added to engine oil.
Blending oils
This and similar questions are of interest to many motorists. Unfortunately, oils cannot be mixed, even if they are oils from leading manufacturers (Shell, Mobil, British Petroleum). Each company produces commercial oils, adding to the oil base a whole range of additives, the chemical composition of which is kept secret. Therefore, when mixing high-quality oils of the same purpose, made in accordance with the requirements of existing engine oil classification systems, but using technologies from different companies, low-quality mixtures can be obtained due to the incompatibility of additives. Oils from different companies are interchangeable, the possibility of using such oils is often indicated by engine builders. But that doesn't mean they can be mixed. The API and ACEA classification systems require mandatory identical test methods (laboratory, bench - motor, etc.) of oils from different companies. If desired (or necessary), automakers can introduce additional tests (or more stringent conditions) for oils.
The same applies to mixing mineral or synthetic oils (sometimes even from the same brand). Synthetic oils, such as hydrocarbon oils, from the same company can be mixed. In this case, the oil manufacturer gives appropriate recommendations and bears responsibility. However, it is not uncommon for oils to deteriorate in quality when mixed. As a result, the engine may rattle as the mixture of incompatible oils turns into a "jelly".
In no case should imported and domestic oils be mixed, especially with the addition of domestic additives. Neither the seller nor the consumer knows the composition of the additives that are added to the oils. Some oils of "domestic origin" are produced by "firms" that do not even have basic knowledge of petroleum products. Sometimes such "specialists" use used oils (even without proper regeneration) for the production of "commercial" ones. Use only oils recommended in the owner's manual.
No "purifiers" ("Tokron" and others) are able to increase the octane number of gasoline. For this, special additives are used - antiknock agents, which are added during the manufacture of gasoline at refineries, or additives. The cause of detonation (a metallic knock is heard while the engine is running) and pre-ignition (the engine continues to run when the ignition is off) can be carbon deposits in the combustion chamber.
The increase in compression in the system “with the introduction of some additives” does not occur due to viscous additives, since they do not have them in their composition, but for other reasons.
It is not advisable to reduce oil waste in an old engine and increase cylinder compression by using high-viscosity oils, since this will indeed lead to an increase in cylinder compression, but not for long. In the future, engine repairs will cost more.
The reason for the "acoustic" noise in the old engine is its wear, so it will be cheaper to repair with the subsequent use of high-quality oil. You can reduce the gaps with additives, but the expediency of this should be sorted out so as not to harm the engine.
It is necessary to make it a rule: use a high-quality engine oil of the same brand that matches the engine and do not mix it with synthetic (or semi-synthetic) oil. The engine will thank for this trouble-free operation. Do not buy oil "from the hands", as the packaging is easy to fake.
Changing the oil and oil filter
Periodic oil and oil filter changes are the most important preventive maintenance procedure. During operation, engine oil ages - it becomes liquid and contaminated, which leads to premature engine wear.
An oil change should be carried out immediately after a trip on a still warm engine, so that the oil drains better along with contaminants.
Raise the car on a lift or place it in a horizontal position on an inspection ditch.
Remove the lower engine mudguard.
V6 petrol engines
Unscrew the oil filter ( ). If the filter is difficult to unscrew, use the special key Hazet 2171-1.
Place an oil collecting container under the oil drain hole and unscrew the plug. If necessary, press the plug when unscrewing to prevent the oil from draining prematurely and drain the engine oil.
When the oil is completely drained, wipe the oil around the drain hole and screw in the oil drain plug with a new O-ring.
Wipe the oil filter installation site and screw in a new oil filter.

When the oil is completely drained, wipe off the oil around the drain hole and screw in the plug with a new O-ring, tightening it to 25 Nm.
Fill the engine with the correct brand of oil.
The second generation of Mitsubishi Pajero is called the "off-road classic" which is still in good demand in the secondary market. The model is aggregated with both petrol and diesel engines. No matter how well the legendary car of the 90s is made, it must be well cared for and serviced in the form of changing the engine oil and cleaning filter.
Refueling volumes and oil selection
The choice of oil viscosity should depend on the ambient temperature. For example, for “cold” operating conditions, one viscosity is suitable, and for a hot climate, another.
- From -30 to +40 degrees, it is better to choose 10w-30;
- From -10 or less (extremely low temperature) it is recommended to fill in 5w-20;
- If the temperature does not drop below -10 degrees, use 20w-40 or 20w-50;
- If the temperature does not rise more than +10, 5w-30 is poured into the engine, and 5w-40;
- Not more than +20 0 C - 5w-50;
- All-weather oils can be attributed to 10w-40 and 10w-50, they are used at an ambient temperature that does not fall below -30 0 C and does not rise above +50.
- The minimum temperature is -15 0 C, 15w-40 or 15w-50 is better.
With diesel engines, you also need to carefully choose the oil.
- At temperatures above -10 degrees use 20W-40;
- From -15 and above take 15W-40;
- From -20 to +40 - 10W-30;
- If the temperature is not more than +20, you should choose the class 5W-40;
- Maximum +10 choose 5W-30 or 5W50.
Regarding the amount of oil required, it is determined based on the configuration and engine power.
The volume of engine oil, taking into account the filling capacity of the oil filter and Mitsubishi Pajero oil cooler, is:
- 4G64, 6G72, 6G74 need 4.9 liters;
- 4D56 - 6.7 l;
- 4M40 - 7.8 liters.
Step-by-step instruction
- Warm up a cold engine. We need to clean the crankcase of the old oil, the more it flows out the better.
- For easy access to the drain plug (and in some models the oil filter is also attached from the bottom) and the bottom of the car as a whole, you need to jack it up or drive into the inspection hole (the best option). Also, in some models, "protection" of the engine crankcase can be installed.
- Unscrew and pull out the dipstick and filler plug. This way we will allow air for a better stack of old mining from the crankcase.
- We substitute a large container (equal to the amount of oil being poured).
- We unscrew the drain plug with a key. Sometimes the drain plug is made like a conventional “bolt” with an open-end wrench, and sometimes it can be unscrewed with a four or hexagon. Do not forget to wear protective gloves, the oil will most likely wake up warm, but you need to be careful.
- We wait about 10-15 minutes until the mining drains into a basin or a cut plastic canister.
- An optional item but very effective! Flushing the engine with a special fluid is not included in the maintenance schedule and is not mandatory - but. A little confused, you will much better flush the engine from the old, black oil. At the same time, flushing with the old oil filter is carried out for 5-10 minutes. You will be surprised what black oil will pour out with this liquid. It is very easy to use this liquid. A detailed description must be included on the flush fluid label.
- We replace the old filter with a new one. In some models, it is not the filter itself and the filter element that changes (usually yellow). Impregnation of the filter with new oil before installation is a mandatory procedure. Lack of oil in a new filter before starting the engine can cause oil starvation, which in turn can cause filter deformation. In general, this is not a good thing. Remember to also lubricate the rubber o-ring before installation.
- Fill in new oil. After making sure that the drain plug is screwed on and a new oil filter is installed, we can start filling in new oil, guided by the dipstick. The level must be between the minimum and maximum marks. Also, you need to remember that after the first start of the engine, a little oil will go away and the level will drop.
- Recheck the oil level on the dipstick after the first start. Let the engine run for about 10 minutes at idle.
