[Gasification] Regarding Combustion Quality of Producer gas

Hi,
I have a question regarding combustion quality of PG.
When we talk about natural gas, in short 'Methane index/Methane Number'
provide combustion quality. For gasolin/petrol it is 'octane rating'. Can
we use 'Methane number' as indicator for PG also ??
Thanks
With Regards,
