For a 50:1 oil-to-gas ratio, use 2.6 ounces of oil per gallon of gasoline. In other words, for 2 gallons of gasoline, one would need 5.2 ounces of oil.
There are 128 fluid ounces in one gallon. To calculate the appropriate amount of oil for 1 gallon of gasoline, divide 128 by 50 for the 50:1 ratio, which equals 2.56. Rounding up that number to 2.6 will provide the appropriate quantity of oil for the ratio.
This same formula can be used for other ratios. For example, a 40:1 ratio requires 3.2 ounces of oil because 128 divided by 40 is 3.2.Learn More

The suggested engine oils that should be used for a Honda XR100 have a rating of 10w-30, which include Pro Honda GN4, HP4 4-stroke Oil, Honda 4-stroke Oil or anything that is equivalent, as stated in the owner's manual. The Honda XR100 is air- and oil-cooled. As a result synthetic engine oils are most suitable since they flow easier in colder environments, exhibit no loss of prime, are highly resistant to viscosity breakdown and possess longer change intervals.Full Answer >
