The oil required for Ariens snowblowers depends on the type of engine used in the machine. For modern equipment, Ariens recommends using 5W30 engine oil in products with four-cycle gasoline engines and two-cycle oil mixed in the gasoline at a ratio of 50:1 in products with two-cycle engines.
Older machines have different recommendations for lubrication, so owners should consult the appropriate product manual. If the documentation for a product is missing, Airens maintains a database of product manuals at its website, Ariens.com, that is searchable by model and serial number. Live chat service and customer service contact information are also provided for additional assistance.
