The fellows on team-bhp (linked in 1st post) are mixing in 2.5% Acetone with good results.
So the question becomes: Does adding X% of Acetone decrease my total fuel bill?
I note that panel-beaters/spray-painters are paying to get their 'dirty' Acetone carted off and incinerated. (as per pgfpro)
That means that you could probably get a good amount for free (or better!) if you drove your
High Mobility, 4 Wheeled Incinerator over to these shops and asked for some.
