Drivers of the 2018 Mitsubishi Outlander often search for specific maintenance procedures to ensure the longevity of their powertrain. One such critical procedure is the oil reset process, which is necessary after every oil change to recalibrate the vehicle's monitoring system. This specific model year requires a precise sequence of steps to inform the computer that fresh oil has been installed, preventing unnecessary dashboard warnings and maintaining optimal engine health.
Understanding the Oil Life Monitor
The 2018 Outlander does not rely on a fixed mileage schedule for oil changes; instead, it utilizes an Oil Life Monitor (OLM) system. This system calculates the optimal time for an oil change based on driving habits, engine temperature, and other operational variables. Resetting this monitor is essential because the system will continue to display "Oil Change Required" even after the fresh oil has been added if the procedure is not completed correctly.
Preparation Before Starting
Before initiating the reset, ensure the vehicle is parked on a level surface and the parking brake is engaged. The engine should be turned off initially, but you will need to start it again during the process. Gather your new oil filter and the recommended 5W-20 synthetic oil specific to this model year. Having these materials ready prevents the need to rush or abandon the reset sequence midway.
Step-by-Step Reset Procedure
The reset process involves turning the ignition to the "ON" position without starting the engine. In this position, you must press the accelerator pedal to the floor and hold it for ten seconds. After releasing the pedal, turn the ignition to the "OFF" position, wait three seconds, and then restart the engine to confirm the reset was successful. This sequence communicates with the vehicle's computer to clear the old maintenance data.
Verification of the Reset
Once the engine is running, observe the dashboard display. If the "Oil Change Required" indicator disappears and the OLM begins to calculate a new percentage, the procedure was successful. If the warning persists, the sequence may have been interrupted, and repeating the steps is necessary to avoid driving with unfiltered assumptions about the engine's lubrication status.
Common Issues and Solutions
Brake Pedal Stiffness: If the pedal is difficult to press during the reset, try turning the ignition off and on again to reset the brake booster before attempting the sequence.
Warning Persistence: Should the warning light remain on, turning the key to "OFF" and back to "ON" without pressing the pedal may recycle the system before trying the reset again.
Electrical Glitches: A dead battery or faulty sensor can sometimes interfere with the OLM; checking fuses related to the instrument cluster may be required.
Professional Assistance
For owners who find the manual process confusing or who lack the confidence to perform the reset, visiting a Mitsubishi dealership is a reliable alternative. Technicians utilize specialized diagnostic software that can reset the OLM with a single command, ensuring accuracy and providing peace of mind regarding the vehicle's maintenance records.
Long-Term Maintenance Tips
Regular oil changes every 5,000 to 7,500 miles, or as indicated by the OLM, will keep the 2018 Outlander running smoothly. Using the correct viscosity grade and filtering the oil properly will prevent the buildup of sludge and ensure the reset process remains a simple formality rather than a troubleshooting exercise for future service appointments.
