My book does not tell me how many quarts of oil go into the 5.4 liter, 1998 4x4 expedition. It seems like it is ALMOST six. Anyone know?

 

It's 6 quarts, if you change the filter (and you should).

 

When I change the filter mine takes 6 quarts. But, remember that the filter is remote so you need oil to fill the pipe and the filter. So after I change my oil and add 6qts I run the engine for a little. Then ck the oil again and end up adding anoth 3/4qt to top it off.

So my grand total is 6 3/4 quarts.

I've changed the oil 25 times on my 250 and 18 on my XP. Been the same every time.

The sticker above the radiator on my '97 states 7.0 qts. I check it after adding 6, and it usually ends up at around 6-3/4 to 7 qts every time. My guess is due to the remote filter plumbing. The average filter supposedly holds 1/2 qt. by itself.

 

7 per the dealer oil change spec.
