What type of oil should I use in the Craftsman 917.275700, and how much does it hold?
Use SAE 30 oil (API-SG-SL) for temperatures above 32°F, or SAE 5W-30 for temperatures below 32°F. The engine oil capacity is 4.0 pints with the filter and 3.75 pints without the filter. Only use high quality detergent oil rated with API service classification SG-SL.
