GT500 oil capacity

[jimhyc]

I assume this question has been beat to death over the years but I can't find a definitive answer on searching. I have a '69 GT500 and the manual says 5 quart with filter, with that the dipstick {correct one} reads full. But the CJ registry says 7 quarts and other sites say 6. This is my 4th CJ and have always ran 5 quarts.

I would run 5 quarts and forget about it unless on a super CJ because the oil cooler radiator and long oil cooler lines easily can account for at least a extra quart. Others may have a different opinion.

This may explain why you saw 7 liters in the registry (source Angel Restauration)

I have seen that TSB before but have not acted on it . I suppose it is better however to have a little too much oil then not enough oil.

I once ran five quarts of oil in the pan, take notation "once"

On a beautiful summer afternoon I was involved in very spirited motoring. Upon several attempts to clear out our valves, we detected some stentorian noise being emitted from our internal combustion apparatus.

Fortunately at the time I was accompanied by a loyal friend and ASE mechanic, who came to the conclusion that we had experienced oil starvation.

This lovely chart was found on "The Mighty 428 Cobra Jet Registry"

Allegedly an old Ford TSB

I have followed its recommendation and have never heard that terrible sound again.

Best of luck

I am not understanding this "issue" at all?

"We" have this Ford service bulletin regarding this subject. WHY does anyone doubt it?

The point of it was to protect YOUR engine in spirited use.

I suppose it is anyone's perogative to act like a total nerd or dips hit? However, the DOCUMENTATION is there and EXISTS FOR REAL. So someone explain it to me WHAT IS THE ISSUE?

IF YOU WANT YOUR FE TO SURVIVE "spirited driving", which I suppose means that you ACTUALLY DRIVE THE THING instead of just staring at it like it is in a museum, maybe you should take the advice of running more oil? WTF, whisky tango foxtrot or MAYBE just put "YOU" in a museum of disfunctionals?

I don't know? This is an absolutely ridiculous position to take that "I should only run 5 quarts". Go back to the planet of your origin because it certainly is questionable that you are from here? 'nough said.

It was all about the drain back speed. In "spirited driving" the oil didn't get back to the sump fast enough and that starved the bearings. The extra quart was enough to keep the sump level above the pickup at high RPM.
If you are going for groceries run 5 quarts. If you want to enjoy the thing without worrying put in 6.

Words to live by. I know i plan to start adding a extra quart .

Please DON'T

I use 6-1/2 quarts.  After I run the car, I let it sit overnight and then recalibrate my dipstick by increasing or decreasing the wavy bends up by the handle. I set the level to read at the full mark cold. I prefer to check my oil cold, when I know it's back in the pan.

That TSB....Ford-Speak.  It states 4 quarts IN THE PAN.  Then it states to up that to 6 and must be meaning in the pan again (not counting the almost a quart in the FL1 filter), but then says 7 if you are changing the oil and filter (Standard oil change maintenance).  Then it states to even add yet another (so 8 ) if you have the SCJ Oil Cooler.    Personally, I don't drive the CJ that hard and use 6 when doing the yearly Oil and Filter change.  Ford seems to be saying we/I should be doing 7 quarts(I don't have the cooler). 
It's been running with 6 quarts at Oil and Filter change time, for about 30 years. I put a scratch mark on the dip stick for the "6 quart Oil & Filter changed" mark.   
Wish they'd done it with a spread sheet with one column for "oil and filter change" and another for "Oil ONLY change".
