I have heard it many times that we are not to use additives. What about moisture in fuel during the winter. Did anybody use anything like PS in their 6.7 last winter and what were the results.

 

Something that doesn't contain alcohol.

 

I've never used additives in my diesels. I also don't let them sit for long periods on MT.

 

I run standyne through the summer every 4 fillups or so and during the winter my entire fleet runs howes. I never had a problem with my emission system on my truck

 

I've used Power Service with every single tank of fuel that has gone through both my '01 and my '08. With the 349000 miles on my '01 and the 26500 miles on my '08, I haven't had a fuel issue yet (knock on wood).

 

Shellbourne Fuels' Diesel Fuel enhancer does the trick in that it has an evaporator in addition to a fungicide and anti-bacteria. 1 OZ treats 15 gallons for ~$1.25. Cheap insurance against unscheduled stops.
