In Plug-in Hybrid Electric Vehicles (PHEVs), like the Mitsubishi Outlander PHEV, certain fluids need more frequent checks compared to others to ensure optimal performance:
- Engine Oil: For PHEVs, similar to gasoline vehicles, engine oil should be checked regularly. Typically, this is done once a month or every 5,000 miles. However, PHEVs might see less engine operation due to their electric mode, which could reduce the frequency slightly.
- Brake Fluid: Brake fluid checks are generally recommended during oil changes. However, since PHEVs regeneratively brake, they may require less frequent fluid replacements compared to purely gasoline vehicles. Still, it’s recommended to replace every 2 years as per standard practices.
- Coolant: Coolant checks should be more frequent than replacements. For most vehicles, including PHEVs, coolant should be checked twice a year but replaced according to the manufacturer’s schedule, such as every 120,000 miles for the Mitsubishi Outlander PHEV.
- Transmission and Power Steering Fluid: These are less frequently checked but should still be monitored monthly and replaced every 50,000 miles.
Overall, while standard practices apply broadly across vehicle types, PHEVs’ reduced engine usage might slightly alter maintenance schedules based on actual usage rather than fixed intervals. Always check your vehicle’s specific maintenance schedule.
