Sigh... It's been quite some time since I lasted posted here or on any Ford Truck forum. Apparently the Truck and I have been moved down to the "Older, Classic, & Antique Trucks" section. LOL!

Well I am the original owner of a 1994 F150 4x4 swb truck. Surprisingly the truck has less than 160,000 miles on it. They are hard miles because the truck is used for when I go camping, pulling a trailer, 4x4 in some very remote and harsh conditions. I've done a ton of upgrades and at the time I purchased it I bought a spare crate engine. Of course this was back when I actually had money to burn. Now days not so much.

I moved that engine around for years and finally with the help of my son in law we installed it. Though the old block upon pulling the heads looked pristine considering everything. I only wish I had held up as well as the truck.

So imagine my shock when after reading various manuals, including the factory spec books, I realized I had been short changing the old girl on oil changes!!! Ford had a fix that I was never made aware of with their dip sticks. The six quart oil pans had the wrong dip stick and would show the correct fill at five quarts. I thought the owners manual that I lost in Mojave desert (fun story for another time) had said five quarts including oil filter is all you needed. Than I saw it listed differently in the factory spec manuals that list only the specs, every spec you can imagine for that series of trucks and vans. It said six quarts with oil filter.
The trucks use a different oil pan as I noticed when I readied the long block crate engine which had the front sump design oil pan and was somewhat smaller, obviously I swapped my old pan and pickup tube. It did not come with a dip stick and since I was using the old pan that was easily installed as well. Even though I did the swap in 2015, I have less than two thousand miles on the new engine.

Here are my questions:
1. Six or five quarts? I'm asking because I want to be sure, since I have not put that many miles on the new engine and I want the correct amount in there obviously. LOL!

2. While I could if six quarts is the correct amount of oil, file a "new" full line mark on the old dip stick, I'd prefer to put in the correct one and that appears to be Ford's F4TZ-6750-D that superseded mine F4TE-6750-CA. So the problem being is there are a ton of the wrong ones F4TE-6750-CA available but, I've yet to find one F4TZ-6750-D. Does anyone know if there are any aftermarket ones that match it?

This old man and his truck wants to thank you in advance. Everyone be safe out there!

I worked as a service tech at the local Ford dealer in the mid 90’s. For oil and filter changes: cars got 5 quarts and truck got 6 quarts. No help with locating a different dipstick. I didn’t know there was an updated part.

 

Thank you! I appreciate the quick response. Than six quarts will be the winning number. I'll post an update if I either find a NOS Ford part or an aftermarket one.

 

All of the truck gas engines in 94 take 6 quarts including the filter capacity, according to the owners manual. In my experience, it depends. If your truck is equipped with the factory oil cooler, it uses a smaller filter, and takes around 5.5 quarts. If your truck does not have the cooler, and uses the larger filter, it will take 6 quarts.

What engine are you working with?

 

Here you go.

Thank you! I've used Rear Counter before and Bob Allen actually directed me to another dealer when searching for a engine wiring harness both he and the other dealer are great folks. I'll give them a call Monday!

Have a great Sunday!

It's a 5.0 with factory auxiliary oil cooler package for towing and uses the Ford F1A oil filter..

If it uses an FL1A it does not have the oil filter adapter for the oil cooler. I have only seen those on 5.8 trucks.

The auxiliary cooler in the grille is for the transmission.

These trucks take between 5 and 5.5 quarts for 5.0, and adding 6 quarts will show over filled on the dipstick.

Some capacity descriptions show 5 quart crankcase capacity and 1 quart for the oil filter. The oil filter does not hold 1 quart, so I don't know why it says this.

My previous 95, current 94 and friends 96 all take about 5 or so quarts, none take 6 to read full.

 

I remember going through this same issue. My '92, 302, 4wd takes 6 quarts with oil filter change. When I bought the '95, 302, 4wd, it showed full at 5 quarts with oil filter change. Even swapping the dipsticks made no difference. So after a little investigation, it appeared that the anomaly occurred somewhere in the late '94 through mid '95 production time frame. Either way, both and my 4.9, and 351 all get 6 quarts with a FL-1A filter.

 

Okay, so the F4TE-6750-CA number is an engineering number not a part number. FYI - the codes found on parts are engineering numbers not catalog part numbers, but they can be used to cross reference one another. I don't know why Ford does this...

F4TZ-6750-D is the right part number, and cross references to the F4TE-6750-CA engineering number.

So, you already have the right dip stick. The oil pan holds around 5 quarts. If you wanted check the accuracy of the dipstick, you could empty the system at your next oil change, add 5 quarts and then check the level and see what you have.

As far as your filter, oil cooler situation... if your engine has the factory oil cooler you would have to use the smaller FL-820S filter. It is not interchangeable with the FL-1A as the threads are different. The additional capacity to the pans 5 quarts will depend on which filter is used.

 

You are correct. I had a case of mental vapor lock when you said oil cooler, I automatically assumed trans cooler. I am getting conflicting info on fill levels so I'll keep this thread going and try to sort it all out. Thanks again!

When I do the oil change on an OBS, regardless of 4.9, 5.0, 5.8 or 7.5, it gets six quarts. I don't care if the owners manual says 5 with one in the filter, or 5.5 in the pan, or whatever it says. Six. Am I doing something wrong? Probably, but to the best of my recollection, once you let the thing warm up, after changing the oil, six shows right where it should on the dipstick, in my experience, and I've not *personally* had any of those engines die for lack of oil, or "over-oiling" while they were in my care.

I would note, this is merely what *I* do, and qualifies as an opinion. You do you.

 

Thank you. Yes I've seen most parts listed the old way using the longer number. Then I started seeing the shorter three and four letter number combination they now use. Anyway, I've also seen where they show the F4TZ-6750-D as replacing the old F4TE-6750-CA and assumed it had been revised to show the correct fill mark for 6 quarts. Sigh.... Unless I had both to see a side by side comparison it's hard to know what is going on. I guess now I'll research oil pans to see which one I have. I'll keep everyone posted. Thanks for your help.

Thank you! I agree six quarts seems to be the norm. I usually check the oil cold no start. But I'll check it when I get home running some errands. Thanks again!
