I've had bad luck with Howes myself. Froze going down the road in VT, -12 temps and pretty stiff winds. Winter blend fuel, too. Power Service got it going again and kept it running so I think I'll stick with it. Heard a few other negative comments about Howes from some other locals, too.
Easiest way to see the difference, is put a bottle of Howes and Power Service outside when it's -10 overnite...... After seeing how thick the Howes gets,you will never put it in your tanks again... 'Nuff said....
