Letting a diesel sit

[ford_truck_guy]

This is the first year my Diesel is now my tow vehicle and not my everyday runner... Besides keeping her plugged in (gets cold here in the northeast).. I will use it for snow removal as it has a plow but if it's like last year,,, no snow..Should I put anything extra in the tank besides my normal - Power Services Diesel Kleen + Cetane Boost.. Will probably sit from late October to May... Or so...

Well......I owned a 5.9 cummins....that sat up here, from end of oct.....thru middle of may........most of winter covered in 2...3 ft of snow,and when it melts.....I turn the key, and go.......never an issue.....for 5.6 years.
I bought my Powerstroke....day before Christmas last year,and it sat till May.....long winter here.......just change the oil in spring........good to go.
NEVER had a charger,maintainer.....on either......and we get real winters up here.

All the above, but I would still start er up and drive a few miles every couple of weeks and keep a battery maintainer on it. 🙂

Is there water in your fuel tank?
Algae will only grow at the water/fuel interface. No water, no algae.
IMO, if there IS water in your tank, you should get the tank emptied and cleaned, then run the fuel through a filter/separator to remove any water and/or dirt.
With a clean tank and clean fuel, you should need no additives, especially if you fill the tank with winter blend fuel, and keep it full. An air space in the tank will allow condensation, and you don't want more water in there!

The white bottle Power Service should help that diesel from gelling, although when it does start to get cold a topping off with #1 diesel will help.

I wouldn't put anything else in the tank.

One thing I have always done, since I have mostly lived on the northern great plains in the Dakotas where cold is king, is change the diesel fuel filters every fall. That way I have fresh filters for the coldest winter months.

Also be sure to check out the battery condition and make sure both are in top notch condition.

Those things done, you should be good to go.
