um, what do you mean? its a ratio... therefore how much oil you put in depends on how much fuel you put in..

lets say you have a 20 litre jerry can. so you fill it up with 20 litres of fuel, and want to mix at 25:1. so that means for every 25 litres of fuel, you need 1 litre of oil. but you only have 20 litres of fuel, so divide 20 by 25 = 0.8. so you need 800ml of oil.

make sense?

Try this web site for a start http://www.at-speed.com/air/oil_gas_calc.html

This may also help

*All of the oil mixtures are for a 1L fuel container*


25:1 = 40ml/L
26:1 = 38.50ml/L
27:1 = 37.03ml/L
28:1 = 35.70ml/L
29:1 = 34.48ml/L
30:1 = 33.33ml/L
31:1 = 32.25ml/L
32:1 = 31.25ml/L
33:1 = 30.30ml/L
34:1 = 29.41ml/L
35:1 = 28.57ml/L
36:1 = 27.77ml/L
37:1 = 27.02ml/L
38:1 = 26.31ml/L
39:1 = 25.64ml/L
40:1 = 25ml/L
41:1 = 24.39ml/L
42:1 = 23.82ml/L
43:1 = 23.25ml/L
44:1 = 22.72ml/L
45:1 = 22.22ml/L
46:1 = 21.73ml/L
47:1 = 21.27ml/L
48:1 = 20.83ml/L
49:1 = 20.40ml/L
50:1 = 20ml/L
