First major service for my Polestar 1 - engine oil & air filter DIY?

Vehicle: 2020 Polestar 1

My 2020 Polestar 1 is approaching its first major service interval, and I'm wondering about the internal combustion engine (ICE) components. Specifically, the engine oil and air filter.

As a plug-in hybrid, does the ICE require the same maintenance as a conventional gasoline car? Can I tackle the oil change and air filter replacement myself, or are there special considerations for the hybrid system? I'm pretty handy but want to make sure I don't mess anything up.

ClearTheCode admin answer:

Yes, even though your 2020 Polestar 1 is a plug-in hybrid, its internal combustion engine (ICE) still requires regular maintenance similar to a conventional gasoline vehicle, particularly for engine oil and air filters. The frequency might differ slightly due to the hybrid nature (the ICE might run less often), but the need for these services remains.

Engine Oil Change:

  1. Oil Type: The Polestar 1's T8 Twin Engine uses a specific synthetic oil. Always refer to your owner's manual for the exact viscosity (e.g., 0W-20) and API/ACEA specifications (e.g., API SN, ACEA C5). Using the wrong oil can lead to engine wear and reduced efficiency.
  2. Filter: You'll need a specific oil filter designed for the Volvo T8 engine. Aftermarket filters are available, but ensure they meet OEM specifications.
  3. Procedure: The process is similar to any conventional oil change: warm up the engine, drain the old oil, replace the filter, and refill with new oil. Ensure you tighten the drain plug and filter to the manufacturer's specified torque.

Engine Air Filter Replacement:

  1. Location: The engine air filter is typically housed in an airbox located near the engine. It's usually secured with clips or screws.
  2. Procedure: Open the airbox, remove the old filter, clean any debris inside the box, and insert the new filter, ensuring it's seated correctly before closing the airbox.
  3. Frequency: Check your owner's manual for recommended replacement intervals. Driving in dusty conditions may necessitate more frequent changes.

Special Considerations for PHEVs:

  • Safety: Always ensure the vehicle is off and the 12V battery is disconnected before performing any work. Be aware of high-voltage components, though these are generally well-protected during routine maintenance.
  • Service Intervals: Because the ICE might run less, some manufacturers adjust service intervals. However, oil can degrade over time even with low mileage, so adhere to both mileage and time-based recommendations.

When to See a Shop:

  • If you're uncomfortable working around high-voltage systems or the engine bay.
  • If you lack the correct tools (e.g., torque wrench for the drain plug).
  • If you prefer to have a professional handle the waste oil disposal and ensure all service records are maintained for warranty purposes.
