A well thought out kill switch helped, but I can't put a figure to it.
The best ecomod I did (and can give a hard result for) was fitting taller tyres to raise overall gearing.
I went from 195/50 R15 to 195/60 R15 for just over 5% MPG gain. I'd go to 195/65 R15 next time, but they may not fit under the strut coils.

that is exactly what I want to do. get slightly taller tyres with almost exact same increase in radius as your tyre change. however im afraid that this will have an adverse effect on power. I travel in very hilly terrain and I might need to gear down more to get up a hill. im still considering eco tyres vs taller tyres as the front tyres need changing. but I don't know what will work in my favour
