hey all. I was changing my oil in my truck the other evening. I put 6 qts of brad penn 10-40 in. this is my first oil change in this truck because i bought it at the end of december and dont really drive it to much. i went to check the oil after a few days and the dipstick level was on the add mark. I was supprised. it does not burn or leak oil. the engine is a jasper 400 with only about 26,000 miles great oil pressure. I noticed when i opened the hood the next day i noticed someone wrote 7qts with a yellow paint stick on the underside of the hood. I did add one more quart and the dipstick read safe. any ideas. the manual says 6 qts. Im stumped. thanks

 

I'd think it'd be 6quarts.

 

I'm aware of the 5-qt pan used on cars and the 6-qt pan on trucks, never heard of a 7-qt
pan, maybe such a thing was used on the F450+ trucks? Or perhaps an industrial
application?

 

It should be 6.5 quarts with the filter.

 

Yeah I can say that my 79 bronco holds 7 quarts, factory pan and it's a 351. Had a buddy with 79 bronco his held 5 quarts.

 

With an oil filter, my 1977 F-150 4x4 with 351M has always taken 7 quarts on a change to be at the full mark.

The 2x4s had a smaller pan as I recall.
