2023 Mitsubishi Mirage Engine Oil and Fluids Instructions

Mitsubishi-logo2023 Mitsubishi Mirage Engine Oil and Fluids Instructions

Keeping your 2023 Mitsubishi Mirage’s engine oil and fluids at the right levels is critical to keeping your car operating smoothly. Here are the steps to check and change the engine oil and other vital fluids: Remove the dipstick once more to check the oil level. The dipstick should be between the “L” (Low) and “H” (High) marks. You must add oil if it falls below the “L” mark. You will need to use a jack and jack stands to lift the car, remove the drain plug from the oil pan to drain the old oil, change the oil filter, and refill the engine with the appropriate oil.

Checking and changing transmission fluid often necessitates the use of more complex tools and skills. It is best to have this done by a professional technician, although you may check the transmission fluid level yourself: Locate the gearbox dipstick (if installed) when the engine is running and the car is parked on a level surface.  Remember that these are just tips; particular techniques and fluid types may differ based on the trim level and model year of your 2023 Mitsubishi Mirage. Always refer to your owner’s manual for complete and up-to-date information on vehicle maintenance.

Engine Oil and Oil Filter

It is normal for an engine to use oil. You may need to add oil between the recommended oil change intervals. Before starting the engine, check the engine oil level. Refill if necessary.
To check the oil level, remove the dipstick, wipe it off, and gently reinsert it all the way. Slowly pull the dipstick straight out and check the oil level by checking the upper sur-face of the dipstick. The oil level must not go above the line on the dipstick.


If it is difficult to verify the oil level, wipe off the dipstick and reinsert it. Wait a moment and then recheck the oil level by checking the upper surface of the dipstick.

If the level does not reach the line which shows the minimum amount of oil required, remove the oil filler cap on the engine valve cover, and fill to within the “Good” range.

  • Overfilling will cause oil aeration and loss of oil pressure, which could damage the engine.


  • Used engine oil is poisonous, and can dam-age your skin. Prolonged and repeated contact may cause serious skin disorders, including dermatitis and cancer. Do not let used oil touch your skin and wash thoroughly after working with it.
  • Keep used oil out of the reach of children.


  • Engine oil consumption is greatly influenced by payload, engine speed, etc.
  • The engine oil will deteriorate rapidly if the vehicle is subjected to severe conditions (for example, repeated operation on rough roads, in mountainous regions, on roads with many uphill and downhill gradients, or over short distances). Consequently, the oil will require earlier replacement in accordance with the schedule in the “WARRANTY AND MAIN-TENANCE MANUAL”.

Engine Oil Identification Mark

Mitsubishi Motors recommends using only engine oils with the ILSAC certification symbol on the front of the container.

ILSAC certification symbol

If you cannot find oils with the ILSAC certification symbol, use an API classification SP or higher oil with the following label.
This mark appears on the top of the oil container and tells you two important things about the oil.

API service symbol

2023 Mitsubishi Mirage Engine Oil and Fluids03

  1. The upper part indicates the quality of the oil.
  2. The center part indicates the SAE grade of the oil viscosity.

Recommended Engine oil vis-cosity

Use engine oil with the proper thickness for the outdoor temperatures where you will be driving.

2023 Mitsubishi Mirage Engine Oil and Fluids04

Mitsubishi Motors Genuine 0W-20 Synthetic Engine Oil is recommended for optimum fuel economy and cold weather starting.
If Mitsubishi Motors Genuine 0W-20 Synthetic Engine Oil is not available, 5W-20 grade oils displaying the ILSAC certification can be used.
However, Mitsubishi Motors Genuine 0W-20 Synthetic Engine Oil should be used at the next oil change to maintain optimum fuel economy and cold weather starting.

To replace the oil filter

The oil filter should be replaced at the time or mileage specified in the “WARRANTY AND MAINTENANCE MANUAL”.
Only use high quality replacement filters on this vehicle. The manufacturer’s specifications for Mitsubishi Motors Genuine oil filers require that the filter can withstand a pressure of 256 psi (1.8 MP). A Genuine Mitsubishi oil filter is the best replacement filter.
Follow the installation instructions printed on the filter.

Engine coolant

To check the coolant level

The engine coolant reservoir (A) lets you quickly see when you need to add coolant. When the engine is cold, the level of the cool-ant in the reservoir should be between the “F” (FULL) and “L” (LOW) marks. The radiator usually stays full so there is no reason to remove the radiator cap (B) except when you check the coolant freeze point or replace the antifreeze coolant.

To add Coolant

Use “Mitsubishi Motors Genuine Super Long Life Coolant Premium” or equivalent*.

Engine coolant

*: similar high quality ethylene glycol based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technology

Mitsubishi Motors Genuine Coolant provides excellent protection against corrosion and rust formation on all metals, including aluminum, and prevents clogs in some parts of the engine.
If you need to add coolant often, or if the level in the reservoir does not drop when the engine cools, the cooling system should be pressure-tested for leaks. Take your vehicle to an authorized Mitsubishi Motors dealer or a repair facility of your choice for testing.


  • Do not use alcohol or methanol antifreeze or any engine coolants that contain them. Using the wrong antifreeze can corrode aluminum parts.
  • The required concentration of anti-freeze differs depending on the expected ambient temperature.
  • Above -31 °F (-35 °C) : 50 % concentration of anti-freeze
  • Below -31 °F (-35 °C) : 60 % concentration of anti-freeze
  • You can check the concentration level with a gauge from an automotive supply store, or your authorized Mitsubishi Motors dealer or service station can check it for you.
  • Do not use water to adjust the concentration of coolant.
  • Do not top off the reservoir with plain water only. Water by itself boils at a lower tempernature and does not stop rust or freezing. If the water freezes, it will damage your cooling system. Do not use tapware. It can cause corrosion and rust.

Radiator Cap

The radiator cap must be sealed tight to pre-vent losing coolant, which may result in engine damage. Only use a Mitsubishi Motors Genuine Parts radiator cap, or an approved equivalent.


Wait for the engine to cool down before opening the radiator cap. Otherwise hot steam or boiling coolant could spray up from the filler port and scald you.

Points to remember

  • Do not overfill the reservoir.
  • Your vehicle uses a special radiator cap that stays sealed and lets the coolant flow from the reservoir back to the radiator when the engine cools down. If you need to change the cap, use the exact same kind.

  • Check the coolant freeze point in the radiator with the proper gauge, and only when it is safe. If you add antifreeze, the con-tents of the reservoir must be protected against freezing.
  • Keep the front of the radiator and con-denser clean.
  • If the engine coolant temperature does not rise after the engine is warmed-up, take your vehicle to an authorized Mitsubishi Motors dealer or a repair facility of your choice to have the thermostat checked, and replaced if necessary.

Air cleaner filter

The air cleaner filter will get dirty and dusty from use and not filter properly. Replace it with a new filter using the schedule in the “WARRANTY AND MAINTENANCE MANUAL”.

  1. Unclamp the cover. Open up the top of the cover and take out the air cleaner filter.


  • Take care not to scratch the engine air flow sensor when removing the air cleaner cover.
  • Replacing the air cleaner filter and put the cover back on in its original position.
  • NOTE
  • Genuine Mitsubishi Motors Parts are recommended when replacing the air cleaner filter.
  • After replacing the air cleaner filter, make sure that the hinges at the bottom of cover are firmly set.

Manual transaxle oil 

Whenever the manual transaxle oil level is checked, add oil to maintain the proper level, if necessary.
Refill or change with the oil according to the table below.

Oil type

Lubricant Mitsubishi Motors Genuine NEW MULTI GEAR OIL ECO API GL-4
Viscosity range SAE 75W-80

Continuously variable transmission (CVT) fluid (if
 so equipped)

The continuously variable transmission (CVT) should be maintained and serviced by an authorized Mitsubishi Motors dealer or a repair facility of your choice to obtain the best performance and longest life.

Fluid Type

Use only “Mitsubishi Motors Genuine CVTF-J4 or CVTF-J4+” transmission fluid to ensure optimum transmission performance.


  • Using the improper transaxle fluid may dam-age the transaxle.

Special additives

Do not use any fluid additives to the trans-mission.

Washer fluid

Do not use any fluid additives to the trans-mission.
The windshield and rear window washer fluid reservoir is in the engine compartment.

Check the washer fluid level at regular intervals and add washer fluid to reservoir if necessary.
Open the reservoir cap and check the level of washer fluid.
Full level is approximately 2 inches (5 cm) below from the upper surface of the reservoir.

2023 Mitsubishi Mirage Engine Oil and Fluids09

When freezing weather is anticipated, flush out the water in the reservoir by operating the pump. Fill the reservoir with windshield anti-freeze (not radiator antifreeze), and operate the system for a few seconds to flush out the residual water.

  • Do not use any fluid other than washer fluid. Also, do not use such as soapy water, glass cleaner, and engine coolant. Using other liquids can cause damage to the vehicle, such as could cause streaking on the vehicle’s painted surfaces, damage to the washer pump, or clogging the nozzle, leading to the washer fluid not spraying.
  • Over-diluting the washer fluid in winter may cause it to freeze onto the windshield.

Brake Fluid

To check the fluid level

The fluid level must be between the “MAX” and “MIN” marks on the reservoir.
