Oil Ratio Question. 46:1 to 32:1

Recommended Posts

I suck at math.

If I have 2.5 gallons mixed at 46:1 how much oil do I need to add to make it 32:1?

If you have 2.5 gal at 46:1, then you have 2.45 gal fuel and 0.0531915 oil (using the ratio).

So you want 32:1 by adding oil. So after you do this you will still have 2.45 gal fuel, but now 0.0531915 + X of oil. And now the total volume is 2.5 + X. Therefore using the ratio, ((2.5 + X)/33)*32 = 2.45. Therefore X is 0.026563; that is the amount of oil, in gallons, you need to add.
