Perhaps for the time it is in there it's not enough to cause a problem but I did a little search and this is what I found on the Web:

It isn't too good but isn't going anywhere near any problematic materials and should drop into the sump. The acetone is just there to dissolve the gunk and allow the oil to get into ring gaps, it will flash off in any case.
Learnt this from an american car nutter who refurbed old motors, it was quite expensive to use more exotic stuff on big V8's so if a cheapo mix would solve the problem without a major strip it was a good call.
