Sean very interesting article. Anyone heard of using acetone in these small amounts? Any risk to engine or catalitic converter? o2 sensors?
From seans article it sound pretty safe and undamaging.
Might try it in the old truck, not much to lose if she dies(1993 toyota with 170k) since we will probably get a new commuter next year anyway.
