Dipstick question, you dipstick!

I changed oil in my 1975 F100 with the 300 engine. It is supposed to hold 6 quarts and I have put in 5 and it reads way over the full line. I know it has 5 quarts because I have pulled the oil pan and drained all of the oil. I am not sure if I have the right dipstick. The number on it is C5TE-6570-C. It says to use SE101-C oil. Doesn't the C5 mean it is for a 1965?

C5 means that it was designed/engineered in 1965. It does not mean it is from a 1965 truck exclusively. It could have been used in any truck in the years following 1965 as well.

Does anyone have a dipstick they could check on their 73 to 78 F100 with a 300?

The oil filter holds a lot of oil. If you didn't fill it prior to installing it (you should), then your dipstick will read lower after the engine has been run.

Yes, I put a new filter on and put in 5 quarts of oil. I have one quart remaining to put in. I ran it and let it sit and it reads about a quart over the full mark. It should read a quart below. So, going by the reading on the dipstick, I have 7 quarts in the pan.

Hmmm, I don't know then. Look at the dipstick tube. If it has been altered or swapped, then your dipstick could be going farther down that it should.

I admit it would bother me too, and I would try to find another like truck to compare oil pans, dipsticks, and dipstick tubes with. But I don't think you have anything to worry about. If you've got the right oil pan, then for now I'd pour in the amount of oil that the owner's manual specifies.

Our 78 has dipstick D7TE-6750-DA

It has a rear sump 4wd pan and I bet that makes a difference. I'm sure someone will verify.

We actually replaced it with a universal one that we made fit, because the original wouldn't stay snug in the tube.

I'll get some measurements for you tomorrow evening.

I would scribe a line for one quart low, add the 6th and scribe a line for "full".
