I thought the "V-Power" at Shell is just your plain old Gasohol 95 + some magic V-Powder added by Shell to make it into V-Power. A marketing ploy, nothing else?!
PTT stations I see still have regular 91, so I go there.
The main idea behind gasohol seems to be to make some politicians rich(er). I am willing to bet that as soon as regular is out completely, gasohol will suddenly rise in price to what regular was before...
