258 I-6: Oil Capacity?

Autozone says 5 quarts. I have read many Jeepers on the net, though, who swear it holds 6 quarts.

Anyone have any input on this subject?

Thanks.
 
All of mine read full w/ five.

I noticed the same discrephancy... but I've never used six (6) quarts, only five. That is WITH a filter change. Five gives me a full 'reading' on the dipstick, and that's good enough for me.

I'd love to know where the six (6) comes from....:confused:
 
uh yep

As usual I'm with Marine-OpLaw. 5 Quarts with a filter change. I have the Haynes manual that shows 6 also. And if I'm not mistaken so does Chiltons.

The first oil change I did on mine I used 6. Man, it is scary to pull that dip stick and see that you're a full quart over full. You're just waiting to hear the seals blow. That didn't happen of course, it would probably take more oil than that.

Have fun!

yep yep 5 quarts

My repair books said the same thing about needing 6 quarts...who in the hell knows where they got that from? I'm with these guys 5 is the number
 
Depends on the number/rate of leaks in your 258 :D :D

Some might be 10-20 before a change, and that's WTIHOUT the filter :D :D

I do 5 also in reality.
 
I remember this coming up when I was younger. My Chiltons said 6, the owners manual said 5. Guy who worked on my Jeep when I was too scared to do it myself said he put in about 5.2 quarts with a filter and that put it dead on the "full mark" on the dipstick.
 
I thought you meant oil consumption........ my bad. I will see myself out.
 
I put 5 quarts plus in but not 6. I use the larger filter J trucks call for. Some books oil filter application books call for the larger one but most call for the smaller one. Larger filter obviously means more oil needed to hit full mark.
 
I almost always change oil myself.. but I was out of town, went to Jiffy. Their books called for 6 qts. Apparently all the FSM's say SIX!? It does look overfilled on my dipstick. I drove for a bit and checked it. No Foaming. I drove a few hundred miles on the freeway, no foaming, no leaks.

But I do wish we could get to the bottom of this annoying riddle. I don't wanna run 5 if it supposed to have 6! I heard a rumor that there may be aftermarket dipsticks sold that were not the right fit? Has anyone ever gotten to the bottom of this?

What have you been running when you did your oil changes?
The dip stick tubes and dip sticks are a matched set.
I know they're different lengths, don't remember which is which, I think the '83 and up are longer.
Is your dip stick original, does it have a part #?

I've been running 5 qts. Also had a head (valve seats) go bad on me after 30k miles (not sure if their related). Now when I put in 6 qts (w/ filter change) it appears to read about a quart overfilled! It's confusing when manuals says 6qts, but then the dipstick reads full at 5 qts.

Yes, my dipstick is # 3242441 and then "M"
 
I use an oil filter for an FSJ . It's a little bigger and I use 5.5 quarts I believe. I always check the dipstick and go from there.
 
This is the 84 owners manual in the glove box. 5 + 1 for the filter = 6 Since I have not filled my engine yet I don't know. I'm going to be watching the dip stick closely.

This all makes sense. But what doesn't make sense is that I just put in 6qts with a filter change (and ran the engine for a bit, then let it settle), and then the dipsticks reads about a quart over "Full".

I'm fine with using 5.5 or 6 qts, but why does the dipstick read FULL after 5 qts (including the oil in the filter?)

Your part # is the correct '83-'86 dipstick.

Do you know the history of the engine?
Is it possible it has the '81-'82 tube?

Maybe if you can post a pic of your tube someone else ( I'm nowhere near mine right now) can compare to theirs to see which one you have.
