1997 Gand Marquis

Hello all,
Found an awesome deal at Auto zone on some Castrol Gold Bottle 10W-30... $4.00 a quart.
Decided to change my 97 oil out in over the weekend. After 7500 miles.
My question is. The oil capacity for that motor is it 5 or 6 quarts ?
Put 5 quarts, not even on the dipstick. Added a 6 th in the cross hatch ?
Then I found a chart on Fordmo that say 5 quarts..

Suppose to be 5 qts, go ahead and drain a quart just to be on the safe side and check the dip stick again.

If you have an oil cooler, it's 5.5 quarts. If not, it's 5 quarts. I would suggest using an FL-820S filter.

my 98 CVPI with a 4.6 took 6 qts with an oil cooler and a FL820 filter

My 96 Merc GM took 5 QTs.

How long did you wait after pouring in the oil until you checked the dipstick? It takes a while for all the oil to drain down to the pan.

Without oil cooler it's 5qt, but if like my '98 will read a 1/4 to 1/3 quart low... I never worry about it, dump some in when it gets down to add...

This^^^ If engine was cold may take 30-60 minutes to drain back enough to get a accurate reading... I can tell you 100% with six and no cooler, it will be over full...

Use the dipstick, that's what it's for

 

[fordman65]

Really ??
Dam let me write that one down..

OK, so how hard do you drive this thing? If it's really easy around town stuff, slightly overfull won't be an issue. If you spin the motor up, it will ...

I don't drive it hard at all. I am not that worried about it. I check the oil very often.
The original question about the oil capacity was from some conflicting information I read.
Owners manual says 5 qts, I also was told at a Ford dealer it required 6 qts.
