l have a 1983 Subaru station waging gl, it has a 1.8l non turbo, do you know what grade oil it takes? AND HOW MANY QUIRTS?(HOW MUCH)

Call a Subaru service manager.

4.2 Qts (4L)

And Subaru recommends a range of oil weights depending on the weather and use.

Any where from 5w30 in the coldest weather to 20w50 in the hottest and/or under heavy usage, high reving conditions.

If you run 10w30 or 10w40 you will be fine for 90% of conditions unless you live in super cold or hot weather.
