4oz of premix oil for each gallon of gas so for 5 gallons of gasoline you need 20oz of premix oil

16 oz of 2 cycle oil to 5 gallons of fuel is 3.2 oz per gallon of fuel. So, two gallons of fuel would need 6.4 oz of oil.
8oz. to every gallon...13 gallons would be 8x13=104 oz.

It all depends on the oil you're going to use. For instance, AmsOil is 100:1. Most 2-stroke oils are to be mixed at 32-40:1. BelRay oil is the leanest recommended synthetic oil at 12.8 ounces of oil to 5 gallons of gasoline. Maxima and Klotz use 16 ounces per 5 gallons. Find an oil you want to use and they will usually have a small bottle just for mixing with 5 gallons of gas. Keep that bottle and use it to measure with in the future.
