What is the oil gas mixture ratio for a Yamaha YZ80?
Answer Oil Gas Mixture You need to find out the ratio of gas to the oil you have. It should be on the bottle. Ex. 36:1 this means 36 parts gas to 1 part oil. You then get a separate contianer that you know the volume of and mix according to the ratio your oil asks for. If you use premium gas this mixture will last longer.
