What is the gas mixture for a Stihl BG 55? ›

Using the right type of fuel is critical in the safe and efficient operation of your STIHL equipment. Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil.

You can also confirm it by looking for the bar code label on the blower housing. This label will provide the model number, serial number and model name. The name will have a letter E following the C, for example BG 86 C-E.

STIHL recommends that customers use a minimum of 89 octane fuel. If a customer chooses to use a 91 or 93 octane fuel, no damage to the engine will result. However, using an 87 octane fuel could lead to serious engine damage.

For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas. For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.

What's more, HD2 air filters can be easily cleaned and reused multiple times: just spray the removed filter with STIHL Varioclean, leave the detergent to take effect briefly, then rinse and dry the air filter before reinstalling it.

Our backpack blower is equipped with a two-stroke engine, and must always be run using a 50:1 mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained.

The following features distinguish the new carburetors from the previous carburetors: – High speed screw (H) and low speed screw (L) now have hex heads. – Narrow access to both screws, (H) and (L), means that carburetor adjustments are possible only in the service shop with a special servicing tool.

How do I properly mix fuel for the Stihl BG 55 leaf blower? To ensure optimal performance, mix unleaded gasoline with a high-quality 2-stroke engine oil at a ratio of 50:1 (gasoline to oil).

Engine Type: 2-Stroke.

Customer: I have a Stihl Bg 55 blower that I am having trouble starting(running actually). It will start, but will not keep running for more than 4-5 seconds or so. I have checked the spark plug gap (. 020), and replaced it with a known good one from an Echo string trimmer with little improvement.
