I never used additives for yrs. then the bulk supplier started putting Howes in my tank when he filled it one winter it got real cold and my tractor quit the filter was solid with parifin replaced it dumped some straight kerosene in the tank and quit using Howes. Then a rod in the injector pump seized up and when I had the pump rebuilt they introduced me to Stanadyne ,The premium all-season, multi-function diesel fuel additive, designed to tackle virtually any diesel fuel related problem. The cost to me is around $45 every time I get the bulk tank filled ( approx. 500 gal.) twice a yr. a rebuild injection pump is $1,200 plus down time. I can't tell the dif. in the dump truck but the backhoe runs 100 rpm faster when I use it ( from 2,200 to just over 2,300.
