Cubic yards, cubic feet, gallons, quarts, pints, cups, fluid ounces, tablespoons, teaspoons and on and on. You didn't say what units you are going to use to measure the oil. I am going to assume fluid ounces. I need to know how many fluid ounces are in a pint. The World Wide Web gives us a very useful way to find this conversion. Just type How many fluid ounces are in a pint? into Google or any of the major search engines. You can also ask google or Siri this question. When I did so I got 1 pint is 16.65 fluid ounces. You now want to fill a 16.65 fluid ounce container with 51 parts, 1 part oil and 50 parts gasoline. 16.65 divided by 51 is 0.33 which is very close to $\large \frac{1}{3}.$ Thus put $\large \frac{1}{3}$ of an ounce of oil into the 1 pint container and then fill it with gasoline. I hope this helps,
