how many quarts of oil does your 7.3 take?

[ianstew]

dave, i know the manual calls for 15 quarts, but i can't explain why mine takes 16 quarts to get full. Is it possible my dipstick is wrong or something? My HPOP res. isn't draining back or anything either. If i put 15 quarts in, i'm at half the hash, and i add another quart after leak checking, and then she's full.

Yes it is there was an updated dipstick for the OBS im betting you dont have it

3 gallon jugs and 2 quarts of rotella. Keeps the oil at a level that doesn't foam up as much. I am no where near stock and I shear the oil down right below 30w at 3000 miles, so I change it every 2500-2800 miles.

All 7.3's take 15 quarts of oil during a oil change. Some truck may register HIGH or LOW depending on your dipstick. Put 15 quarts in, and let it go. Check your oil level EVERYTIME you fill up. 7.3's are known to use oil for MANY reasons. I had a 7.3 that would use 2 quarts every 1000 miles. She had 300k+ on her when I sold her and she is still running at 545k. And as said before, don't change your HPOP oil!

I dont think the hpop change would be bad. with the truck changing owners. I did it to mine the the oil was quite a bit thicker than new oil. (150K)
I don't think it would have a negative effect on the truck.
please inform me if I am wrong.

It will not make a difference. It flows through the engine just like the rest of the oil

i'd go crazy leaving it less than the full mark after an oil change, im almost OCD about the oil in my truck, i've got to get a new dipstick. i couldn't walk away knowing the hash was only half covered.......man i get shivers thinking about it right now.......

I realize this is an old thread, but my 7.3 takes 3 jugs of oil, and 3 quarts of oil in addition to get full is that normal?
