Not looking to debate the merits or potential "dangers" of the chemical motor flush, but out of curiosity, what is your favorite and why? 5 minute motor flush? Kerosene? Kreen? Liqui-moly? ATF? Diesel?
There are big differences in price point and availability between all of these, so wondering why you may prefer one over another?
