I have always used PS white bottle with good results, until this year. I split a full 100 gallon bottle between the 2 19 gallon tanks last Friday morning.
We had forecast of snow Monday morning so I drove the powerstroke so I had 4x4 just to make sure I could get home from work.
Tuesday morning I tried the 83 it was cold enough that it wouldn't spin fast enough to fire. Ended up driving the powerstroke again.
It was about 8° at 4:00 Wednesday morning and I was able to fire the 83 the 7 mile drive into town went fine. Worked until about 6:45 at my part time job, truck fired up fine and everything was going good until about halfway to work.
After about 5 miles on the highway I noticed it was losing power, not really for sure what exactly was happening I switched to the front tank. It picked back up and ran good for another couple miles before I started noticing it getting sluggish again, made it a couple more miles and was barely able to hold 45mph.
I pulled off on a side road to see if i could figure out what was going on, as soon as I stopped it surged a few times and died. Spun the fuel filter off and looked at the fuel, it was still liquid but was cloudy looking. On a whim I dumped the filter and grabbed a new bottle of PS, filled the filter and dump the rest in the front tank.
Jump back in the truck and after about 5sec of cranking with the accelerator on the floor she finally fired, had to hold the accelerator at about half throttle for about 30sec to keep it running.
After it would finally stay running at an idle I jumped back on the highway and it seemed to clear up after a couple miles and run normal.
I'm not sure exactly what was different this year but I treated the fuel the same as I always have and have dealt with much colder temps and this is the first time I have ever had an issue.
