Just wondering if my ariens st350 snow machine uses detergent or non-detergent oil? Thanks

Hello. Actually, Many snow thrower manufacturers now recommend using synthetic motor oil particularly for subzero temperatures. Synthetic oil, such as Mobil 1 doesn’t contain any of the waxes that cause conventional oils to congeal in cold temperatures. As a result, synthetic oil makes starting easier and also prevent parts from running dry when a cold engine first starts. Synthetic oil also has higher film strength and stands up to high temperatures better than conventional oils. You’ll pay more for a quart for a full synthetic and you still have to change it as often as conventional oils, but you are giving your snow thrower engine the best chance for a long trouble free life.
