i only use caltex vortex 98 in everything car, boat, bike, mowers and anything else i get hold of [except the work van i only use vortex diesel in that]
i have never had any fuel related problems in anything using vortex fuels
i dont see the point in saving a couple dollars in poor fuel
just on a side note ethanol fuel would have to be around 40 cents a litre cheaper then premium to actually work out cheaper in most cars
