maybe some people know this,but one can save around 15% on fuel through adding for petrol .17ml to 1 litre of petrol and diesel.13ml/litre diesel of pure acetone,it also after a tank or so will produce hardly any emissions,as nearly everything gets properly burnt,it also cleans one's engine up nicely,no coke build up

Get a syringe & just squirt it in after filling ones tank up..
