Any chance you can take a photo of your dip stick showing the part number and post it on this thread for comparison? Also when was your Bronco built?I recently performed an oil change on my 2.7L and managed to take out/drain close to 6 and 3/4 quarts of oil. The oil level readings on my dipstick has always been consistently in the nominal mark ("B") so I do not believe it was overfilled from factory. I put ~6 and 3/4 of quarts back in and the dipstick indicates that my oil level is nominal.
