    Question about oil.

    I just bought an 02 wrx and the previous owner has been running synthetic in it, I was wondering if I could switch to standard oil without any damage to the engine and such?

    Yes. You can interchange any oil as long as it's the correct viscosity and API rating. Check your manual for the specs; any oil meeting them is OK.

    I thought you weren't supposed to switch from synthetic to dino oil?

    Any oil meeting the manufacturers viscosity and grade specifications is by definition appropriate for use in the motor. The manual will have the correct specs; from memory, my motor calls for an API SL oil with a viscosity range in the 5W/10W-30/40/50 range.

    I cannot think of two API oils that are not miscible, and the manufacturer calls for API oils.

    A Subaru representative mentioned in a written response to a query about synthetic oils what I just said about any oil of the correct spec, plus a clause about not switching back from a synth but the reasons given were -- from memory -- at best, very leniantly, nonsense.

    When switching from any type or grade or brand to another the consumption seen at least initially may differ from what it was previously, so it's always good to keep a close eye on it. Otherwise, any two API oils of the correct spec should be miscible.

    +1 ! It is perfectly fine to switch back.
