Killem is an extremely effective biocide. It is not a fuel additive, as it works only in the water phase of the fuel, which is where the bacteria grows. Wipes out any bacterial growth it comes in contact with. A little goes a long way. If you have a current problem it is recommended that you double dose the treatment twice, then continue to use preventive doses. 1 ml treats 5 gallons. We ship a 10 ml syringe with each bottle to enable you to easily treat your fuel (dino or bio) in vehicle or in storage. Works equally well with WVO. If you don't have a pair of good chemical handling gloves, get these
, inexpensive and very good protection.
