Mitsubishi Eclipse
Data verified by Nick Marchenko, PhD
Maintaining your 1999–2012 Mitsubishi Eclipse is essential for optimal performance and longevity. This model offers four engine options: the 4G64 and 6G72, both 2.4L and 3.0L I-4 engines, and the 4G69 and 6G75, both 3.8L V-6 engines. Each engine has a specific oil capacity of 4.5 quarts, with the 4G64 and 6G72 requiring a viscosity of 5W-30, while the 4G69 and 6G75 utilize 5W-20. Additionally, coolant capacities vary, with the 4G69 needing 9.3 quarts and the 6G75 requiring 8.6 quarts.
Regular oil changes are crucial to ensure your Eclipse runs smoothly. For the 4G64 and 6G72, maintaining the right oil viscosity and capacity will help achieve peak performance, while the 4G69 and 6G75 engines benefit from their specified 5W-20 oil. Always check your oil levels and coolant regularly to prevent any engine issues.

What type of oil does the Mitsubishi Eclipse use?
Oil viscosity depends on the engine: 4G64, 6G72: 5W-30; 4G69, 6G75: 5W-20. Check your owner's manual for the correct spec for your specific engine.
What is the coolant capacity of the Mitsubishi Eclipse?
The coolant capacity for the Mitsubishi Eclipse varies by engine: 4G64: 7.4 qt; 4G69: 9.3 qt; 6G72: 8.5 qt; 6G75: 8.6 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the Mitsubishi Eclipse use?
The Mitsubishi Eclipse uses different types of oil depending on the engine. The 4G64 and 6G72 engines require 5W-30 oil, while the 4G69 and 6G75 engines use 5W-20 oil.
How many quarts of oil does the Mitsubishi Eclipse take?
All engine options for the Mitsubishi Eclipse, including the 4G64, 4G69, 6G72, and 6G75, have an oil capacity of 4.5 quarts.
How often should I change oil in a Mitsubishi Eclipse?
It's generally recommended to change the oil in your Mitsubishi Eclipse every 5,000 to 7,500 miles, depending on driving conditions and the type of oil used.
What is the coolant capacity of the Mitsubishi Eclipse?
The coolant capacity varies by engine: the 4G69 engine requires 9.3 quarts of coolant, while the 6G72 needs 8.5 quarts and the 6G75 requires 8.6 quarts.
Does the Mitsubishi Eclipse need synthetic oil?
While synthetic oil is not mandatory, it is recommended for better performance and protection, especially in extreme temperatures. Always refer to your owner's manual for specific recommendations.
What happens if I use the wrong oil viscosity in my Mitsubishi Eclipse?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to use the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that calculates the remaining life of your engine oil based on driving conditions and engine performance. It alerts you when it's time for an oil change.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oil, it's not recommended as it can reduce the effectiveness of the synthetic oil's benefits.
How do I know if my Mitsubishi Eclipse has an oil leak?
Signs of an oil leak include visible oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regular inspections can help catch leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets, leading to oil burning in the engine. Regular maintenance can help identify these issues.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is cold, as this provides a more accurate reading. If the engine has been running, wait a few minutes for the oil to settle before checking.
What is the difference between an oil change and a flush?
An oil change involves draining old oil and replacing it with new oil, while an oil flush cleans the engine's internal components to remove sludge and deposits before adding new oil.
