it's a tradeoff for sure. oil.. even 140w or even 300w marine oil.. will slowly leak out of a bad seal.. even in cold territories.
00# grease may weep a bit but won't leak very much even out a bad seal.
00# grease will slowly slump to fill a void as created in the steering box by the sector gear rotating and the ballnut moving up and down... the sticky nature of the grease makes it cling to the gears and lube well.. at the end of the day when the machine is sleeping, the grease slumps back into place to recoat everything for the next work day.
since this isn't a high speed gear box or a tranny or a diffy.. drag from cold lube is a real non issue. The grease won't be freezing.. so that's a non issue as well. I've packed a steering gearbox with short fibre stiff axle grease before... because it was all I had.. ..ie #4 grease..and needed to get a job done..and... with the extreme mechanical advantage a worm setup gives... it really made no difference on the steering.. honestly.. on a 2wd non power stering setup.. grease.. oil.. whatever you pack the box with.. as long as it lubes.. it will be fine... besides.. once you steer lock to lock once.. you open a void, and just have the sticky residue on the worm and gear surfaces anyway.. I'd wager that's less drag than even a light 30w oil bath.
lots of mower gearboxes can also use a 00# grease. my howse 10' mower can use either 140w oil.. or 00# grease. have seen landscape maint equipment that also uses 00# grease in their gearboxes... it's not all that uncommon.. look at the jd application.. their 00# grease is 'cornhead' grease.. as in.. it goes in those header gearboxes...
