Im going to mix water with the Petrol to make it go a bit further & then put a throttle stop to allow only 6mm of travel. Take the engine back to standard & then take off the Turbo. All these years with a Cossie & i didnt realise fuel ecconomy was the main aim. Im not sure towing mine with my Pug 107 will improve things but im going to try that next. Its got me thinking I may be best selling it & buying one of those Prias things.
