I replaced the drain plug on mine with an oil drain valve QuickOilDrainValve.com - the best way to change oil I attached a short piece of rubber hose to it and no more messy cross member.

As for the 5qt/6qt question, I worked in a gas station when I was a kid and changed the oil on tons of these trucks. We always put 5qts in them with a filter change and they were full according to the dip stick.

Those who are hired to write manuals don't always have a clear knowledge of the subject they're writing about, which may be the reason that '65 manual seems a little unclear in what they mean. I seem to recall my dad talking about car companies of that era encouraging people to run the oil longer than the standard 2K-3K and just change the filter at the 2K-3K interval. So I've always interpreted that "*" asterick to mean that if you change the filter but do not change the oil, you need to add 1 qt. If you were doing a complete oil/filter change it required approximately 5qts.

 

Ford put the drain plug there as a special option assembly-line additive; That's the reason we have self lubricate anti-rust prevention crossmember .

 

You can lead a mule to water, but you cannot make it drink.

There's nothing unclear in any 1965/66 owners manual, and the oil change intervals during this time were every 2000/2500 miles, depending on dusty/sandy conditions. The filter was changed every other time.

Doncha think someone who bought new, then owned the same 1965 F100 for 43 years would know the correct oil capacity?

Doncha think someone who worked the back shop parts counter for over 30 years would know how many quarts of oil to charge out on repair orders?

ASTERISK * in 1965/66 owners manuals: SIX quarts of oil with a filter change. Not 5, not 5 1/2, but SIX.

In today's world, how many of y'all know if the oil pan and/or dipstick in your truck is the original and correct parts?

Oil pans are usually not marked, but the original dipsticks have Ford ID numbers stamped on them.

How old are you Randy...close to 45? How old were you when you worked in gas stations? 15-20? How old were these trucks when you changed their oil? 15-20 years old.

Oh, and btw...since most of y'all don't know, or are to young to know, or weren't even thought of yet...Ford had a new program beginning in 1965. The design of the filter was new, and there was new premium oil.

The filter was painted gold, the oil came in gold cans. Ford called the oil & filter: The Quality Twins.

 

Well, Bill, I appreciate your position, however you're the only person I know who has ever put 6 qts of oil in these things. Mine seems to be full with 5.

I guess this mule ain't thirsty yet......

 

But, you aren't aware if your oil pan and/or dipstick is correct. I know mine was, and...

10's of 1000's of lube men poured 6 quarts of oil into 10's of 1000's of these trucks as that's what the owners manuals/shop manuals said to do with a filter change.

 

slightly off, but my 300 takes 6 full quarts with a filter change. It's not the original dipstick, and Mr. Wilson here, the wonderful man that he is, gave me the measurements and I was able to take an EFI dipstick and cut/mark it to be correct. So I know for sure the dipstick is right. also, someone please correct me if I'm wrong, but I believe at least a good majority of Ford engines require 6 quarts? I know for sure the 5.4 triton does.

EDIT: Actually Bill gave me measurements for a 240 which is what I thought the engine was, but then i pulled the head and found out it was a 300 and found Sanderson Ford had one NOS dipstick with the rubber gasket at the top in great shape. picked it up for like 11 bucks!

 

On these older hi mileage ford f100 pickups what type of oil would you'll recomend, the traditional oil or the synthetic oil. Also what weight of oil could you'll suggest and why these types of oil. I made my first oil change this weekend and I put Royal Purple 0-40 synthetic in, whats the census here. Thanks for the discussion. Kevin Felix

 

I believe ND when he says his truck takes 6 qts, my trucks oil pan has probably been changed because if I put in the 6th qt, my truck smokes out of the left exhaust!! With 5 qts in the pan, no smoke!! One thing that I did notice is that when I cahnged the oil filter it was empty, oil had drained back into the block. Is this normal?

 

I would trust Bill on this one. Dipsticks can get replaced in the 45 years or so that these trucks have been in service. If there is any doubt about the dipstick being original, just fill the engine with 6 quarts on the next oil change and note the level on the dipstick. Then take a file and make a groove at the new full mark.

 

My problem is not the dipstick, it has to be a different oil pan. Engine smokes with 6 qts in oil pan!

 

I am here for the very reason you are discussing, I keep getting mixed signals online as to what an automobile 352 takes for oil. I just got my 66 Galaxie and no manual with it, so was hoping to find out what it takes when you change the filter.

I will start with 5.

 

332/352/390/410/428 passenger cars: 5 quarts w/a filter change. The filter is Motorcraft FL1A

Done a few oil changes on FE engines..........I have always dumped in six. Every ford V8 I have ever serviced is 6qts, same with 300 sixs.

I belive the falcon sixes used 4 qts.

 

This is from the '65 owner's manual:

Approximate Capacity
170: 3.5 qts.
240: 4
300: 4
352: 5

*Add 1 quart with filter change!*

 

I have a 1965 F100 along with the original owners manual , I looked it up a couple of weeks ago and it reads 5 quarts. I puttem in (all 5 quarts) along with a new filter. After starting it up and then killing the engine for several hours I checked the oil level and it read right on the full mark.
