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.

1Also, 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 EldredgeCommented Dec 29, 2014 at 22:46

3It usually says right on the filler cap. Have you checked there?– Pᴀᴜʟsᴛᴇʀ2 ♦Commented Dec 29, 2014 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 AlsopCommented Dec 31, 2014 at 14:59
