Gasohol in Thailand

Cormac writes: Following the switch of the state-owned TPI to supplying gasohol only, Shell Thailand is now moving the same way. This in-your-face advertising
campaign was seen while filling up on Sathorn Road. (The sign just reads "Shell Gasohol 95 - ensuring quality that everyone will be comfortable with".)
Currently Thailand's gasohol is a blend of around 90% gasoline with alcohol produced from locally-grown sugarcane, replacing imported MTBE. It can be used by any vehicle without adjustment and reportedly gives slightly better performance.
