How many quarts of oil is needed in the 1966 428?


Asked by Nov 15, 2007 at 10:12 PM about the 1966 Ford Thunderbird

Question type: Maintenance & Repair

I need to know the right amount of oil to put into my 1966 with the 428 as i am not sure if I have the proper dipstick..I am thinking it should hold around 5 qts??..but when I added that much I was way over the full line

I'm pretty sure it is 5. Grandpa had a '61 with a 390 which took five. Most of the larger Ford V-8s took 5 quarts with a filter change. Did you change the filter at the same time as the oil? If not, you might only need 4. Your dipstick may also not be correct.

5 qrts with filter.

The 428 Qcode motor holds 4 1/2 qrts. of of oil, period. The 428 motor oil for this big block should be changed every 2500 miles... Jeff, Naples, Fl.
