What engine oil does a 1992 Subaru Liberty auto station wagon need? Answers in "W" units please.

I need to add oil and I cannot find a good reference as to what to use - the oil at the garages are 20w/50 w etc and I have no idea what to use.

    Have you checked the owner's manual? – Nate Eldredge Dec 29 '14 at 22:44

    Also, what you call "W units", like 10W40, is the "SAE specification" and actually measures the oil's viscosity at low and high temperatures. See mechanics.stackexchange.com/a/12701/1419 for much more detail. – Nate Eldredge Dec 29 '14 at 22:46

    It usually says right on the filler cap. Have you checked there? – Pᴀᴜʟsᴛᴇʀ2 Dec 29 '14 at 23:49
  • It will depend on the engine size and running. Subarus typically use 10W40, 5W40 or 10W30 but your manual will tell you which you need. – Rory Alsop Dec 31 '14 at 14:59

4.5 liters of semi-synthetic 10w40.

  • Please provide a reference. Also, which engine was this for? – Zaid Dec 17 '15 at 8:10
