Default Re: proper 70cc oil mix?

i was going by the 80cc manual at
Gas and Oil Mixture for Fuel ratio
The engine is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 4 tanks of fuel), the ratio should be 16 to 20 parts gasoline to 1 part oil. After the break-in period, the ratio can be increased to 20 - 25 parts gasoline to 1 part oil. In hot climates or long trips use a rich oil mixture.
I built my bike using online and paper maual,but by mistake i used the online manual for gas/oil is what my paper manual says:
The engine is a 2-cycle design,therefore a gasoline/oil mixture is necessary,during the breakin period(1st gallon of fuel)the ratio is 18:1.after breakin the ratio increase to 25:1
