Do you use them and if so what brand and how often?

 

I use power service,one bottle every tank fill,haven't started yet,probably wait until temps avg. around 32

 

I have used Howe's Lubricator since the mid '80's when I started driving in Alaska. I have never had a water or gell up problem. I use it year round since it keeps the fuel system cleaned out and, with LSD and now ULSD, it provides some lubricity. Did some reading on it quite a while ago and liked how it did its thing. Sometimes, it is best not to fix something that isn't broke, and Howe's has always done its job well. I have always gotten good injector and fuel filter life using the product. Also use it in my Jeep Liberty CRD and, while others have had injector and EGR problems, I haven't had any mechanical issue. Maybe just good luck.

There are a number of other good products. Power Service is not a bad one either. Howe's is pretty cost effective and does a bang up job. This time of year, you can find good prices on it and pick up a few cases.

Either way you go.... cold weather and ULSD are a mix that you will have to be proactive in preventing a problem.

 

Almost a million miles on my injectors, and I've never used an additive.

Additives only seem to help with water, and if you keep your fuel free of water, you'll be fine in that department.

I find with gelling(should be called "waxing") additives don't help. Once the fuel turns to wax, and plugs your fuel filter, no additive will help you.

I haven't had a problem with either, and I shut my truck off to -20, and have started it at -40 outside, with just the engine heater on for 3-4 hours(not plugged in).

 

Allan, the reason you don't have problems is because you only run the Great White North. The fuel in a given region is already formulated to withstand that regions temps. Those of use the run across multiple regions run into problems because we're buying fuel that may not be formulated for the temps we find ourselves in a few days later.

I use Howes when I have to. Usually I just fuel up when I first get to a cold weather area and it does the trick.

 

I have a coffee before work, and a shot of Jack and a Bud after I get home.

I start fine, and never freeze up.
