if is a lawnmower use the norma 5w10 oil due to the small engine or they have their own oil..I used on my won 12HP

Hydrogear transaxels take a multi grade oil 20-50 the filler is a brass plug on the top, there should be a 1/4" air gap at the top to allow for expasion, Tuff Torq units also take a multi grade oil 10-30, these units normally have a resevoir on the top with upper and lower fill marks.

Check and see if there is a sight glass on the side of the pump. If there is, just fill it until the oil shows up about half way in the sight glass.

I am sure that Sears has there own oil they would prefer you use, If not a quality brand of SAE 30 is commonly used in these compressors.

a mineral based 20/50 ,cheapest you can buy and change every 6000m
