Question Oil for an STI?
How much oil do you fill for an STI. The manual says 4.2, my old Rex used 4.8.

The manual says 4.2 quarts, but I've heard that's for the non-turbo models and that the turbo models hold 4.8.

The manual says 4.8. Put in 4.5 (including what you use to fill the filter before installing it), run the engine, later add a few ounces if needed to reach full mark.
