I own an Ariens 924036, which is a 5HP Tecumseh engine, but can't find in the owner's manual how much oil it needs. I dropped an entire 32-ounce bottle of oil into the snowblower a few hours ago and just checked the dipstick but there is barely a drop of oil on the dipstick!

Any idea how much oil I need? Your response would be appreciated tonight, as we're expecting 4 to 8 inches of snow tonight!
