well i suppose i am just gonna have to find out the hard way, no harm in trying it, however i may think that the ratio will definetaly improve my mpg as it does tend to be in sorta high revs all the time, in 5th gear i'm 98% sure that at 60mph im at 3500rpm or very near that and always thought that to be high for a 1.9 engine,but currently doing 30mpg,, i also have a 2.0l vauxhall vectra and at 60mph in that its around 2600rpm.
