My own personal test Howes vs. Power Service vs. Stanadyne

So I have ran power service white bottle or grey bottle since I purchased my truck in October 2012. I haven't had much to compare it to other than running without it and it seemed to improve mpg's when I used it so I have kept on doing that. This year I jelled up and I had about twice the recommended amount in the fuel due to extreme cold temps -40-45 with windchill. I am now using stanadyne for the last few tanks. I haven't noticed a huge improvement or possibly at all? Temps haven't been as cold so not sure if it would jell or not? I picked up some Howes today and hoping this stuff is the best because it is cheaper than Stanadyne and easier to get. It will be a while before I can test all three brands but will update as I see Positives and negatives of each. I probably won't go power service unless it really stands out above the rest. What are some experiences you guys have had as far as jelling? Mpg increase? Etc...

I gelled up with power service white bottle and Motorcraft Anti-Gel. 2 separate tanks, 2 separate additves. I think the base fuel has more to do with it than the additives. They may help a little but it's apparent to me it can't be totally prevented when an area experiences record low temps.

My 7.3 seems to like Howes the best. Got my best to date mpg's running it. I put it in an old stabil bottle for easy measuring.

My 7.3 gelled while driving up the interstate in Indiana in -5* weather with Power Service treated fuel.

I'm sure condition of starting fuel has a lot to do with it. But I am noticing a "slight" increase in mpg using the stanadyne vs power service. Looks like we are getting another cold front here in southern Wisconsin so this will give me an opportunity to test the stanadyne in cold weather! I sure hope I don't gel up again, I can't afford to keep changing fuel filters pre-maturally.

I've gelled twice this winter. Once using Power Service and once with Howes. Both times with diesel 1, or at least that's what the station clerk claims. Will be trying Stanadyne next.

i am running power service. had my truck in storage @ 15 and 20 below no plug in available. Never gelled always fired right up. I think base fuel is more important than anything else i do notice better throtle response and mileage with power service so i use it AND 2 stroke oil

After using power service and gelling up twice, in -18. I finally listened to the old man and switched to Howe's. I have only had one issue with it and I am almost certain it was the fuel that I got that caused it. I also believe not draining the water regularly will also cause you to gell more often.

With Howe's I have noticed about 1.5 mpgs better then power service. I use a quarter bottle every fill up. A little over kill probably but after sitting on the side of the road freezing my balls off I'm not taking any chances.
