How to Refuel a Single Stage Snow Blower. Refueling a single stage snow blower is a little more complicated than just refilling the gas tank. Single-Stage snow blowers have 2-cycle engines which require an oil and gasoline combination in the gas tank. Most engines take oil directly, but two cycle engines take oil as a mixture with the gas in the gas tank.

Two-Stroke vs. Four-Stroke

You can usually tell a two-stroke engine by the cloud of stinky smoke that surrounds it when it's first started up.

Two-stroke engines (also called two-cycle engines) require you to mix the oil with the gas in exact amounts, and most people like to eye-ball it.

Four-stroke (four-cycle) engines have a separate compartment for oil, so you don't have to measure things out like a scientist.

New snow throwers only come with four-stroke engines. The only two-stroke engines you'll find are the old ones that have already been around the block a few times.

If you're tired of mixing oil and sniffing fumes, it may be time for an upgrade to a cleaner, easier, 4-stroke model.
