    On the cap to the engine, it is written: SAE 5W30.
    But I do not know if it still corresponds to the current oils.
    I would not break anything
    Thanks for your help.


    Best regards.

    5w 30 is still a common oil in the USA and is fine to use
    You can also use many synthetics like Mobil 1 5w40 or 0w40

    Hello Cutlass 442 ,
    Thanks for your answer.


    In France too we find oil 5W30.


    But I don't know if they still match the type 5W30 1986?

    For here: http://www.kroon-oil.com/en/product-...ponent:341174/

    They speak of multigrade oil 10W40 for Fiero.

    If a modern oil 5 W30 is correct for that engine, I put it to.

    And a gearbox too ?

    Regards.

    Christophe.

    Yes a modern 5w30 is still fine for the engine

    I don't know about the manual gearbox

    For the automatic transmission gearbox you want dexron transmission. Fluid

    Thank you Cutlass 442 for your help,
    I also asked a friend in Chicago, Fiero specialist ( http://www.paulvargyas.com/) , manual transmission, use to the same oil.
    Modern 5W30 oils are OK for her.


    Motor oil 3.8 liters of 5W30.
    Manual transmission gearbox has 2.5 liters of 5W30 oil.

    Thanks for all.

    Best regards

    Christophe
