What is the fuel mix on the 162?

50:1 fuel : oil ratio. You can use E5 or E10 unleaded petrol within the chainsaw, however E5 fuel has a longer shelf life, you should also use a good quality 2-stroke oil as it offers better lubrication. Using a mixing container or fuel can you should measure out the oil and fuel before giving it a good mix. Using a mixing bottle such as the Stihl 00008819411 will allow you to mix smaller amounts of fuel at a time, whilst the HP super metered bottle allows you to measure out quantities of oil for mixing within a fuel can.
