Oil Capacity: OBS vs. NBS

I just finished up working on my instructor's '97 F-350. It needed a new oil pan & dipstick tube. When I got the oil pan, I measured all dimensions to make 100% sure it was the same size as the one that came out & it checked out OK. I also made sure the new dipstick tube was the same length & besides a really bad bend in the old one, they're both the same length. Now, when I put the oil in it today, I primed the oil filter & installed it. Then I put in 3gal of oil & the dipstick's reading almost to the full line in the operating range grid......:confused::confused::confused: I haven't gotten to start the truck yet to build up oil press & let it warm up(because of rain), but whatever little the filter would need to fully prime & whatever amount of oil will fill the engine I know won't require another gallon. My NBS takes about 4gal. Do OBSs have less oil capacity than an NBS????

They take the same amount of oil.
Yup both 15 quarts. IIRC there was an updated dipstick for the OBS. I could be wrong though
CRAP! I've gotta get this truck started & see what the dipstick looks like after it's been warmed up. I think I did hear the same thing about an updated dipstick though, Dave. Even though the dipsticks were the same length, the bends were different. I'll have to call Ford & see what the skinny is. Thanks, guys!:thumb:
