Engine oil and filter change

Engine · every 500 hours or every year

Eurol: engine oil 14 L, change every 500 hours or 12 months, first change at 50 hours. The oil and the filter are changed together. Oil grade and filter number were not found for this generation: check your handbook. (The dealer lists ACX5232920 for the Gen4 312, but the S4 engine is a different version, so do not assume it fits.)

Step-by-step
  1. Park on level ground, lower the linkage and any implement, stop the engine, take the key out and chock the wheels.
  2. Warm the engine first so the oil drains well, then let it stand a few minutes. Hot oil burns, so wear gloves.
  3. Remove the sump drain plug and let the oil drain fully.
  4. Remove the old oil filter and clean the filter seat. Wipe a little clean oil on the new seal and fit the filter as it says on the filter.
  5. Fit the drain plug with a new gasket and tighten it to the torque in your handbook.
  6. Fill with the oil in the notes, run the engine for a minute, stop, wait a few minutes and check the dipstick. Top up to the mark, not above.
  7. Check for leaks at the filter and plug.
