Just changed the oil in my 7.3 which calls for 15 quarts. Ended up putting in 16 quarts by accident. Any reason for concern? I could drain a quart but it is cold and windy outside. Let me know what you think.

 

I've heard of people putting 4 gallons in theirs before. I don't think it will hurt anything but more experienced people will be along shortly.

 

No worries. I've done that over 50 times on purpose. Seriously.

 

Welcome to FTE. I don't think you're going to tear your motor up by doing this. How much over does it look on the dipstick?

Well I would hope so. If you did it over 50 times on accident we'd start to wonder about you.

 

I just did it, and no problems.

By the way, Welcome to FTE!

 

I did it too on my last change, not used to the 5 gallon bucket fills. About or a little less than the width of a school pencil above fill mark.

 

You would have figured that Ford would have made our 7.3's with a 4 gallon/16 quart fill just to keep it simple? I think the 15 quart fill was created to ensure we buy the 3 jug/5 quart MC oil??

 

Anyone know if over filling is a myth? What really happens if you over fill?

I always thought any excess would come shooting out the dipstick.

 

I always put in 3 and most of the last gallon, every time it is low. Maybe it's the way the driveway leans though I haven't noticed it leaning. Either way, mine seems to want 4 gallons.

The deal with not over filing it is so you don't get excessive amount of oil hitting the crank and foaming up.
