Wow. Then I would suggest definitely not putting any in. I would use gasoline but that's just me.
Naphtha is a very light fuel that is is used as a cut feedstock for ethanol or as white gasoline in high and regular grade road certified fuels. Butane and additives are typically required, along with blending, to make Naphtha road-ready.
The Naphtha produced by the P2O process is ultra-clean and ultra-low sulphur.
