Well I got very similar answers. Does your method hold up for any percentage calculation? I remember chemistry class where we had to do such equations for so many solutions using the solute and solvent. And you couldn't just add in the amounts together because then the ration changes depending on the total volume you were talking about. And I thought there was a interesting formula we used to do it. But that was centuries ago...well a lot of decades anyways... lol Chemistry was not my best subject...electronics was!

@aspeck, after reworking your answer, which I was getting as well, you have not made a 50:1 ration of gas to oil. You now have a 49:1 ration of gas to oil. If you take your 15.36 number (768/50) and multiple it time 49, you will get 752.64 and then add in the 15.36 for the oil, equals 768 which is exactly 6 gallons in ozs. But it isn't a 50:1 ratio anymore, it is now a 49:1 ratio. I fall into that same idea and mindset. And that was why I was asking how to figure it out with a formula to give an exact 50:1 gas to oil ratio. And I am only using the typical 2 cycle mixture for this example. Not that it matters one way or the other. Just interesting.If my math is correct, and I am looking at this correctly, you are looking at 752.62 oz (5.88 gal) of gasoline to 15.36 oz of oil.

50/1 = 128x6/X

50/1=768/X

1X=768/50

X=15.36 oz of oil.

768-15.36=752.62 oz of gasoline or 5.8798437 gallons.
