Fpts and intermolecular bonding

Will,

You can lower the FPt (i) by branching the hydrocarbon chain (use more of a catalytically cracked high Mr feed stock) or (ii) by shortening the chain length (use more of a more petrol/naptha like cut). Its a Van der Waals / London dispersion forces argument.

I would guess that either of these routes would push up costs but the fuel guys will answer that better than I can, I'm just a chemist....and yes yes I appreciate the possible use of (non hydrocarbon) additives.
