Engine Oil and Oil Filter
To check and refill engine oil 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. NOTE 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.
CAUTION
- Overfilling will cause oil aeration and loss of oil pressure, which could damage the engine.
WARNING
- 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.
NOTE
- 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. 
- The upper part indicates the quality of the oil.
- The center part indicates the SAE grade of the oil viscosity.
Recommended Engine oil Viscosity
Use engine oil with the proper thickness for the outdoor temperatures where you will be driving.
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.
CAUTION
- 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 temperature 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.
WARNING
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 contents 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”.
- Unclamp the cover. Open up the top of the cover and take out the air cleaner filter.
CAUTION
- 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.
CAUTION
- Using the improper transaxle fluid may dam-age the transaxle.
Special additives
Do not use any fluid additives to the trans-mission.
Washer Fluid
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.
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.
FAQs
