FE Oil capacity...
If you read the owners manual...
1966 version, pg 59, top center block with all of the engines oil capacities..ALL engines EXCEPT the 240 6 in 2WD trucks and 170 6 cyl. engines use 5 quarts.....at the top of the lil box its noted as 'Approxamate Capacity*'
Below the box with all of the capacities is the answer to the lil teeny tiny asterick which isnt the easiest to see if you are blazing thru the reading...or simply looking for you CID and capacity...
it says ' * Add 1 quart with filter change'
5 plus 1 is...well...I for one had a lil mud in my face as I too thought it was a 5 quart total cap. engine vs 6 I discovered in a little light reading...

Engine's can handle a quart low or a quart over full capacity; its the trans where you need to be more precise.
I change my own oil and have for most of my life, from what I can gather, all the service centers in my area all use 5 & filter.
As noted in another post, 5 with filter hits the full mark on the dip stick in my truck.

Just changed my oil in my 240 I6, it took 5 quarts and is setting on full. I was wondering what most people run for viscosity in these I6 engines?

Note the asterisk that follows Approximate Capacity*
It refers to this: * Add ONE QUART WITH FILTER CHANGE.
Most F100/350's from 1954 thru 1996 took SIX quarts of oil with a filter change (1983 and later F250/350 diesel engines excepted).
Passenger Cars with I-6 & V8 engines from this same time frame took FOUR quarts of oil, FIVE if the filter was changed.
So...if in doubt:
Screw the manual and the horse that it rode up on.

Are you too dense to understand Ford Motor Company printed that manual? It came in every new 1966 Truck.
Are you too dense to understand that Ford Motor Company said that excepting 240 I-6 2WD's, 240 I-6 4WD's and the other engines in F100/350's used SIX QUARTS with a filter change?
Do you have your trucks operators manual?

thats ALL in a STUPID BOOK...as you call it...
heres some other info for ya...from a favorite book of mine...
heres some oil pan info of cars vs trucks for ya...
65-6 352 2WD F100/250 trucks use a C5TZ6675E
65-6 352 4WD F100/250, F350 Use a C5TZ6675F
65-6 352 Full size Fords use a C7AZ6675A
the books btw this info is from is Ford Master Truck Parts catalog and Ford Master Car Parts catalog respectively...Truck catalog print date is Jan. 1975 and Car catalog print date is May, 1975.
How do I learn this stuff...cause I READ the books.

I don't mean to interrupt this lively discussion between you and the boys, but I don't understand just how a '65 or '66 Ford would get a '67 (C7-) oil pan?
I guess if the original part # was superseded to the '67 part number then that would make sense.......

10-10W for temps for below 10 degrees to 20 degrees above zero
20-20W for 20 degrees above zero to 90 degrees above zero
SAE 30W for temps above 90 degrees
If you are in an area where its really cold most days...below -10 degrees F it says 5W-20 or straight 5W
FWIW...it also says to avoid speeds above 65 when using 5W oil...
The 66 manual says as follows:
below 0 degrees F..5W-10W-20 for multi viscosity. single viscosity: SAE 10W
minus 10 degrees F to32 degrees F: SAE 10W-20W-30 for multiviscosity, SAE 20 for single viscosity.
32 degrees F to 100 degrees F: SAE 20W-40 for multiviscosity. single viscosity: SAE 30.
above 100 degrees F: SAE 40 Only
the 65 manual has this info on pg. 9
the 66 manual has this info on pg. 8
This info pertains to ALL gasoline engines.

Thanks for the info. I was wondering because I decided to run SAE 30 in my truck. I was running 10W30 before with some Marvel Mystery Oil and there was a little clattering in the top end. I ran that oil for about 2 months and when I changed it, that was some of the blackest oil I have ever seen. No chunks but I think the Marvel Mystery Oil did the trick in cleaning everything out. Now with the strait SAE 30 the clicking has decreased dramatically. After the long drive yesterday the truck Idled smoother than it has ever and it just sounded really good. The truck has a glaspack (Cherry Bomb) for the old timers about half way back and the exhaust ends at the end of the Glass Pac. My Sons like the sound of the truck when I am downshifting because it pops but I think I am going to go get the exhaust ran out the back. Can anyone tell me how the original exhaust ran? Did it go strait out the back or did it curve out the side?
