The specs regarding oil for a Troy-Bilt blower can be found by looking in the owners manual. If it isn't around, use the web (www.troybilt.com) and pull up a copy. (You'll need your model number & serial number to view the manual.) It's SAE 30 lubricant, by the way, and the original oil by Briggs & Stratton (the manufacturers of the engine) is available from Sears. (The wise person would call ahead.)
