Just wondering where dose all the fuel go? If I have a 8oz tank and I get .5oz of exhaust where does it go
8 oz goes in 8 oz comes out.

Law of conservation of mass states that for any chemical reactions the reactants mass will equal the mass of the product, So what ever the mass of the air / fuel that goes in the same comes out but it may be in a different form (ie it can go in or come out in any of the 4 stats , solid/liquid/gas/plasma but chemically it well be have identical number of atoms)

so what ever is in your fuel coming out your exhaust.
