I only use additive when its under 10 degrees. Even then sometimes i dont bother. My truck started this more at -5 with no additive, although it was a little rough at fisrt and additive would have helped.
You use a fuel additive every time you fuel up in the winter time. Just ask any fuel hauler that puts it in the ground at the truck stops. Better yet, just look at the pallet of additive sitting by every TA/Pilot fuel drop tanks. TA most of the time keeps them at the entrance of the front door.
Unless you haul under 10f all winter you must waste tons of money on additive. Depending on brand its like 15- 20 bucks a fill up
Nope; then again, my "rig" at the moment is a school bus, and the company/ISD I work for won't let us add anything except our butts in the seat. The only additive I use on my Lightning right now is Sta-Bil, because it sits more than it drives right now. I've used Lucas Oil fuel additive/lubricant, that I got awhile back (when it was a DD), when a few threads were touting using 2-stroke oil in gas to lube injectors and increase fuel mileage--conceptually, it at least should lubricate the injectors, tho it likely doesn't do squat--and I honestly didn't see any increases in power or mileage. I know Sta-Bil works as advertised: I've used it for years on lawnmower and weedeater fuels, even when I had a few acres and stored 20-odd gallons of fuel over the winter. So: pay alot for something you can get for 10¢ on the dollar as a basic solvent, and maybe get some kind of difference, which may or may not save you money; or, let it go, use decent fuel, and additives that actually do something (like water removers or Sta-Bil), and use your money elsewhere??
You missed my point. Every TA and Pilot and some small fuel stops, drop additive in their tanks in the winter time before each diesel drop. No need for a driver to pay extra.
