16oz of oil for 5 gal of gas
Every 40 ounces of gasoline add 1 ounce of oil for a 40 to 1 mix. You do the math.
A 40:1 ratio would work out to 3-3.5 oz. of 2 cycle oil, to one gallon of fuel.
There is a very simple solution to find your ratios. There are 128 ounces in a gallon and since we are always using a ratio of 1 for the gas all you need to do is divide 128 by the gas side of the ratio. The standard ratio seems to be 40 to 1 (40 : 1) gas to oil in which case we divide 128 by 40 and get 3.2. This means you need 3.2 ounces of oil for every gallon of gas. (128 / 40 = 3.2) I am confused as to whether you are asking for a 125 to 1 ratio or are confused and mean a 1 to 25 ratio. Here are a few values for gas mixing. 125 : 1 ratio is 1.024 ounces per gallon of gas 25 : 1 ratio is 5.12 ounces per gallon of gas 50 : 1 ratio is 2.56 ounces per gallon of gas 40 : 1 ratio is 3.20 ounces per gallon of gas
A 40:1 ratio would work out to 3-3.5 oz. of 2 cycle oil, to one gallon of fuel.
It simply means that the 2 cycle engine requires a 40:1 ratio of gas to 2 cycle oil. This translates to 3.2 oz of oil per gallon of gas.
If the banshee hasn't been bored or altered then there is one ratio mix. The gas to oil ratio mix should be 40 to 1 .
That is 40 parts gasoline to 1 part oil.
It can be either 32:1 or 40:1. The 32:1 is a richer mix so if you are fowling plugs, switch to the 40:1. I run 40:1 and I have had no problems. 32:1 = 4 oz oil per gallon of gas40:1 = 3.2 oz per gallon of gas
First, read the instructions that came with your trimmer and find out exactly what the ratio is, usually something like 40:1. It's really important to get it right to avoid starting or running problems. You can buy pre-sized bottles of oil to mix with a gallon of gas. If you do that, there's no guesswork or measuring. Just pour the entire little bottle into a gallon of gas, shake to mix it, and you're ready.
There is 128 oz in a liquid gallon so to achieve a 40 to 1 ratio you would add approximately 3.2 oz of 2 cycle oil to one gallon of gasoline.
40 to 1
When mixing oil with gas you must first determine what ratio is required. Most 2-cycle engines require either a 32:1 or 40:1 ratio. That's 32 or 40 gallons of gas for each gallon of oil.
