Aurus Senat 4.4 V8 Hybrid (2019): Engine Oil and Oil Filter Change

The twin-turbo 4.4 V8 works together with a mild-hybrid system (electric motor and 9-speed automatic transmission). Because of the turbocharging and high thermal load, change the oil and filter strictly on schedule, or more often with city driving and short trips. Take the exact fill capacity, viscosity and oil approval from the owner's manual: there are no reliable values for this vehicle in open sources. You do not need to touch the high-voltage part of the hybrid system for this job.

Difficulty: Medium Time: 1-2 hours Steps: 14 Tools: lift or inspection pit, socket and wrench set (for the drain plug and the filter cap or housing), torque wrench, drain pan with ample capacity, funnel, rags, and if needed a puller or a dedicated socket for the filter cap

Part

  • 🔩 oil filter (filter element in the cap or housing) and a new filter cap O-ring, new drain plug sealing washer. Fully synthetic engine oil meeting the approval and viscosity specified in the owner's manual. Exact OE part numbers for this model are not documented in publicly available service materials, so no part numbers are given. Buy a "filter + O-rings" kit made specifically for the Aurus 4.4 V8

Step by step

14 steps
  1. Warm up the engine for 5-10 minutes to operating temperature so the oil is thin and drains better. Shut off the engine and let it sit for 5-10 minutes so the oil drains down into the pan.
  2. Park the car level on the lift or over the pit. In hybrid mode the car may start on its own, so switch the ignition off, remove the key from the cabin, keep it well away from the vehicle, and disconnect the negative terminal of the 12 V battery if the service procedure requires it.
  3. Remove the lower engine undercover (plastic or composite panel) if it covers the oil pan and filter. Note the location and length of the fasteners.
  4. Open the oil filler cap on top of the engine so the oil drains more easily.
  5. Position the drain pan, unscrew the oil pan drain plug and let the oil drain completely, at least 10-15 minutes. The oil is hot, so wear gloves.
  6. Clean the drain plug seat, replace the sealing washer and install the plug. Tighten to the manufacturer's specified torque (for plugs like this typically around 25-40 N·m (18-30 lb-ft); check the exact value in the manual).
  7. Locate the oil filter: on engines of this type it is most often a cartridge element in a cap or housing on the cylinder block or in the V between the cylinder banks. Place a pan under the housing and loosen the cap with the dedicated socket.
  8. Remove the cap, take out the old filter element and let the oil drain. Remove the old cap O-ring and clean the seating surface.
  9. Lubricate the new O-ring with clean engine oil and fit it on the cap. Insert the new filter element, screw the cap on by hand until it stops, then tighten with a torque wrench to the specified torque (plastic caps take a low torque, so do not overtighten, to avoid stripping the threads).
  10. Pour in fresh oil through the filler neck, about 80-90% of the capacity given in the manual, then close the cap.
  11. Start the engine for 30-60 seconds, make sure the oil pressure is normal and the warning light goes out. Check the drain plug and filter cap for leaks.
  12. Shut off the engine, wait 5-10 minutes, check the level on the onboard computer or dipstick (depending on trim) and top up to the correct level. Do not overfill above the maximum.
  13. Reinstall the undercover and lower the car.
  14. Reset the service interval indicator through the onboard computer menu (the procedure is described in the owner's manual; if there is no menu item, diagnostic equipment will be needed). Take the used oil and filter to a recycling collection point.

Common mistakes and warnings

  • Do not overtighten the drain plug or the filter cap: the aluminum oil pan and the plastic cap are easily damaged. Use only oil of the approval and viscosity specified by the manufacturer, otherwise problems with the turbochargers and the hybrid system are possible. The exact procedure and fill capacity for this model are not documented in publicly available service materials, so only the general principle is given here; verify all values against the manufacturer's service information. The vehicle has a high-voltage hybrid system: do not touch the orange cables and components. If you lack experience or need to reset the service interval with diagnostic equipment, contact a repair shop.
