How much oil does your lawn craftsman lawn tractor need?

drain the old oil, replace the oil filer and put in some new oil. need to know where oil filler is

currently North Carolina

A non-commercial model would be about 500-600 lbs.

I have a Craftsman 19.5 hp lawn tractor that was new in 2000. There is a sticker under the hood on the right side that says it takes 48 ounces of oil, the owner's manual says 3 pints.

There are factors that will effect this answer. What model the tractor is, what engine it has, what transmission, what condition, where it is being sold, what time of year it is being sold etc......
