How Do You Mix a 50:1 Gas-to-Oil Ratio?
To mix a 50:1 gas-to-oil ratio, pour 5 gallons of gasoline into 12.8 fluid ounces of engine oil. Quantities can be adapted, but achieving the appropriate balance is vital for safety and engine performance.
Before mixing, it is important to read and fully understand the user’s manual for the relevant engine.
Choose the right container
Select a container that is approved for holding gasoline. This will ensure minimal loss, whether by spillage, evaporation or permeation.
Use high-quality fuels
Avoid cheap or poor-quality gasoline. Go for higher octane ratings (at least 89) to lower the risk of engine heat damage and piston seizure. The same goes for oil. Choose premium quality for the best engine protection.
Calculate the quantities
As a general guide, a 50:1 gas-to-oil ratio equates to 1 gallon of gasoline to 2.6 fluid ounces of engine oil; similarly, 2.5 gallons of gasoline will require 6.4 fluid ounces of oil.
Mix the gasoline and oil
After pouring the oil into the container and adding the gasoline (taking care to avoid contact with the skin), screw the lid on and shake the contents well. Be sure to use this mixture within three months, shaking each time before use.
