[urq] Acetone fuel additive, your opinion please

[Maurits Jonkergouw]

Has anybody ever used Acetone as a fuel additive (max. 0.3%) in the past (or 
present) and what are the possible short / long-term effects? Does it lean 
out the mixture? Does it 'clean' any carbon residue way too much and thus 
better not used with old engines such as ours?
