oil dipstick inaccurate?

[gingerbreadman]

(77 f250 351m) It took 6.5 liters (6.8 quarts) of oil to get it into the safe zone on the dipstick.

The ford manual says it should take 5 quarts of oil. What gives ? is there an adjustment on the dipstick or something?

Do you have the correct dipstick?? Do you have a larger volume oil pan??

Could drain it, pour back in, and mark new dipstick location. As long as it's a stock pan, should be fine.

all stock as far as i know, looks stock.

my 85 300 i6 was the same thing it took 6 liters to get it to the top of the safe mark and it was stock guaranteed.

2 qts over is an awful lot. it is a science to really read a dipstick correctly with new oil in the pan. but it sounds like you have a 7 qt. pan. theres no way your car should have almost 7 qts. in it stock. it will mess up your motor and cause it to run sluggish. if anything you should use a little less than 5 usually due to some oil still left in the pan after draining. i dont have the measurements offhand but maybe someone could tell you how long your dipstick should be. maybe yours is too short and incorrect. a new one is cheap!

i had a simalar problem on an old 302 as well. When i removed the valve covers one day i got oil all over the place. the valve stem umbrellas had hardened and broke off the valves plugging the oil return passegases, making the oil return down pushrod holes.
