  • Decision made.
  • A short while ago I posted a question about what oil I might use in a 2004 Mercury Grand Marqius I bought. It only has 30,000 miles on and still looks brand new, except for a couple of bad spots in the paint which seems to be a normal problem of white cars from Fomoco of that vintage. The owners manual was actually in the trunk, it calls for synthetic blend so I decided I'm going to run full synthetic. I don't see a problem with going that route since it is so low mileage. God Bless, Beth and Allen.

  • Already answered this. 5W-20 is what Mercs spec out from that era. My daughter has a 2002 sable and when I went on-line to find a downloadable Owner's Manual, I found several Mercs with that oil spec. What does the sticker on the radiator shroud or under the hood say? they put that info on stickers there too nowadays.

  • We had an 06. I believe that motor uses 5w-20 oil which I always thought was very thin. But it seemed to work fine. Most oils are fine these days.
