In a 6 gal tank how many oz. of oil at 50 to 1 ratio?

128 oz = 1 gal.

So, 6 gallons = 128 X 6 = 768 oz.

So, the ratio mix is, 50:1 or for every 50 ounces add 1 ounce of oil. [50 equals one part]

So, 768 divided by 50 = 15.3 [this represents 15 parts]

So, add 1 ounce for each part, you have 15 parts, so the answer is.....

Add 15 ounces
