you will have to check your manual on that one.. or fill till the check plugs are happy.
i'd plan for 'quite a bit'
i know my 5000 takes a couple pails plus.
i don't recall what my 4600 took when i serviced it earlier this year.. but i buy utf by the 5g pail.. multiple pails at a time.. it will for SURE take well over 5g
