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..

It was tried in the 1970s. It doesn't work.

Its gets even worse because acetone costs money to buy and will probably damage the engine as well as giving absolutey no benifits.

Quite. Thankfully the suggested dose is so low that the only effect will be a placebo. Petrol is a good solvent in its own right, and perfectly capable of keeping its injectors clean.

That's good news. I've been using Snake Oil until now, but I'm having difficulty getting enough snakes and rendering them down to extract the oil is a right PITA.
