Hi, new here.
My father recently gave me his '93 grand marquis.
He no longer had the owners manual, so I have no refence.
We have been using normal octane, but have noticed a bit of pinging.
Need to find out if we've been giving her the wrong fuel, or if we need to have the compresion/timing checked.
Does anyone know the octane, or have an owners manual for a '93 they can check?
Kind Regards,
Dain
