So you have been using this snow blower of yours for a long time, but now it seems like no amount of oil is enough for it? Or you just bought one and did not know the amount of oil it takes. And you don’t want to make mistakes with it? We can go on and on about why anyone wants to know the amount of oil a snow blower needs. But all the same, you are on the right page. Here you will know the amount of oil suitable for your snow blower.

But first, why is so much emphasis placed on the oil?

If you’ve been using a snow blower for a long time now, you already know how significant the type of oil you use for your snow blower is. Just the type of oil used in a snow blower can single-handedly damage the snow blower engine. Yes, that powerful, noisemaking thingy in the snow blower can develop faults because of its oil.

Even with a new engine, it takes time for the engine to get used to the oil even though the oil is fresh:

  • When parts move against or rub against each other, there is friction. The oil prevents friction.
  • It protects the life of the engine and keeps it running smoothly.
  • It lubricates the snow blower engine.
  • Have you ever wondered why used oil comes out dark? It is because it cleans the internal parts of the snow blower
  • It also regulates heat and helps to cool down the mower system.

Without the oil, the engine would hardly run even for a minute. Not having enough oil in the snow blower impacts the snow blower as not having at all. It’s not just that; you also have to be careful not to pour too much. This is because excess of it could also affect the snow blower.

While some engines come with a separate tube or tank for the oil, others need you to mix the oil with the fuel before pouring it into the tank. This is why manufacturers recommend a certain fuel to oil mixture to avoid pouring more than expected.

How Much Oil Do Snowblowers Take?

Snow blowers come with different types and sizes of engines, and so the amount of oil varies for each. The power of the engine influences the snow blower engine’s oil capacity. The oil content in the 123cc, 179cc, and 208cc engines is 20 grams, while the 277cc, 357cc, and 420cc engines can contain 37.2 ounces.

Pouring more than is instructed into the snow blower oil tank will cause a lot of damage to not just the engine but to the snow blower as a whole. It could cause the sparks to get dirty easily, produce excessive smoke, and have difficulty starting. Like I would always say, “a healthy engine is a healthy snow blower.”

The oil used in the snow blower should be fresh, and to prevent the snow blower from going off when in use, make sure you fill the tank. Every engine also has its oil recommendation in terms of type and amount. To know which is best for your snow blower, you can always contact manufacturers or check your user manual.

How Much Oil Do Snowblowers Take?

How Much Oil Does An 8hp Snowblower Take?

Tecumseh manufactured most 8hp engines. They manufactured this engine not only for snowblowers but also for weed trimmers, refrigerators, generators, lawn mowers, and lots more.

The engine is about 71 inches wide, 15 inches deep, and 17 inches long, with an elevation of 89 inches. It would take about 24 to 26 oz of fuel to fill the tank with that dimension. This is almost equivalent to and less than a quarter. But if you cannot or do not have a tool for measuring it, you can use the dipstick. All you have to do is to pour the fuel until the dipstick says full.

An 8hp engine is most likely to have a displacement of about 290cc to 301cc.

How Much Oil Does A 208cc Snowblower Take?

As mentioned earlier, a 208cc snowblower can contain up to 20 ounces of oil. This is equivalent to 600 ml. In a Briggs and Stratton engine, the 20 grams of oil recommended contains 600 ml of oil and 2 grams of sugar, equal to 2.3 quarters of unleashed fuel in the US. According to the manufacturer, 5W-30 oil should be used.

A 208cc engine in most snow blowers is a single-cylinder engine. It is also a 70mm bore with 54 mm of strokes. It also has a 9.50 torque.

How Much Oil Does A Troy Bilt Snowblower Take?

For a Troy-built snowblower, you will need about 20 to 22 ounces of oil to fill it. If not, you can check the left side of the tank to see the oil level. The manufacturers recommend using high-quality oil. An SAE 5W30 oil is the best and most advised oil. It works well at a minimum temperature of 20 degrees Fahrenheit and a maximum of 40 degrees Fahrenheit.

In place of the SAE 5W30 natural oil, you can use an SAE 0W30 synthetic oil. For temperatures above 40 degrees, you should use an SAE 30-weight oil of single grade.

Although the brand of oil you use is not a big deal as far as it is of high quality, It is recommended that the oil used in the troy built snowblower is changed after the first five hours of use. And just like every other snowblower, the oil should be changed regularly.

How Much Oil Does A Craftsman Snowblower Take?

Some craftsmen’s engines only need 20 ounces of lubricating oil, but bigger engines could need up to 40 ounces. To find out how much oil your Craftsman snowblower needs, consult the owner’s manual. Whatever amount you find, make sure to use a detergent and oil mixed kind of oil.

When the temperature is above 0 degrees Fahrenheit, Craftsman user manuals advise using a 5W30-weight oil in most of their snowblowers. Although some repair shops advertise 5W30 engine oil for snowblowers, 5W30 motor oil is typically the same whether used in a car or a snowblower.

Still, on the amount and type to use for a Craftsman engine, you might wonder if you can use synthetic oil instead of natural. The manufacturers agree that you can use synthetic oil but under certain conditions. If the temperature where you reside is unstable and plummets, only then can you use synthetic oil. They also recommend using a DW30 synthetic oil. This oil works well at -40 degrees Fahrenheit and over 0 degrees.

As I mentioned earlier, whether you use synthetic or natural oil, it should be an oil and detergent mixed type.

Can You Put Too Much Oil In Snow Blower?

Yes, you can. This is possible when you make a mistake with the mixture or amount of fuel that is supposed to go into the fuel tank. When this happens, there is a possibility that the snow blower will get flooded. It can cause the engine to lock up, smoke and not run well,

  • The engine locks up:

If the oil in the engine is too much, it will overflow into the cylinder. This makes the engine turn hard. This is most likely to happen to engines with different oil and fuel chambers. If the overflowing oil comes in contact with the rings on the engine, it will cause a reaction called hydro-lock. It happens when oil enters the chamber meant for only fuel.

  • The engine smokes:

When there is too much oil, the oil might touch the spark plug. When it touches the spark plug, it disrupts the spark that is supposed to ignite the engine. Thereby causing the engine not to start or it stops when in use.

It can also flow into the valve train in the engine cylinder. When inside the cylinder, it might get burnt and produce a thick white cloud of stinky smoke.

But thankfully, most snow blowers are designed with a system through which the excess fuel can be expelled. It is the crankshaft. Apart from that, there are other ways you can remove excess oil from your snow blower before using it.


The size of snow blower engines differs and so the amount of oil will be different too. While 21 ounces of oil might be enough for snow blower A, it might not be for snow blower B. Also, the snow blowers are compatible with some particular brands. That is why you can’t use any type of oil for your snow blower.

Whichever snow blower you use, make sure you follow the instruction on the user manual for its use. Or else, you might just be opening doors to too many snow blower problems.
