Anti-gel over kill?

Have you seen it gel up at freezing temps? Id like to see it. I store it in sidebox at single temps and it doesn't gel up. Who told you it gels up?

 

Another poster claimed to have a bottle gel up. I didn't believe it myself but I guess if it's on here it must vbe true.

 

If it's getting cloudy, what do you think is happening?

 

I think the "gel" comment was sarcastic. The first comment was.... it pours better at warmer temps. Never had any problem myself. But I run the lower 48.

 

In years past, when I used fuel treat more often, never had a problem with treat looking cloudy or not as it should be. I usually use Power Service brand.
As I researched and through the experience of use and non-use. Now when I use it, a hand full of times a winter, the stuff works as advertised. Coldest temperatures I have used it was about -20 F ambient.
I like today, 39F in Wisconsin.
Good luck .

 

You're thinking of it wrong. Fuel treatment drops the cloud point of diesel even lower by a certain amount, or at least within a range of a certain amount. Howe's by itself isn't preventing you from gelling up. The cloud point of the diesel you're getting is changing constantly based on predicted temperatures. The two together combine to prevent you from gelling up.

Bear with me because these are not real numbers. So if Howe's drops the cloud point by let's say 10-15 and your diesel has a cloud point of -5, you now have a cloud point of -15 to -20. That's assuming you followed the directions. The fact that Howe's gels up on its own is not concerning at all, other than if you can't get it into your tanks because it's so bad.

If the fuel companies weren't working to prevent you from gelling on their end, then you would need to worry about Howe's gelling up. That's why I mentioned in one of my posts you need to watch getting fuel from places that do low volume of fuel sales as the cloud point of the diesel may not reflect current weather conditions since it's been sitting in the tanks for awhile.

 

In my current 17 yr old Volvo w/Detroit Series 60, I have used PS winter treatment the last few years if going to be below zero or so. If going to be much below -20 I don't shut my truck off.

About to buy the WS (my avatar) with DD15 which has a heated fuel/water separater. Downloaded the owners manual to get ready for it. From the manual:

Fuel Additives
Detroit Diesel engines are designed to operate satisfactorily on a wide range
of diesel fuels. The use of supplemental fuel additives is not recommended due
to potential injector system or engine damage. Our experience has been that
such additives increase operating costs without providing benefit.

WATER CONTAMINATION
Some fuel additives claim temporary benefit when fuel is contaminated with
water. They are not intended to replace good fuel handling practices. Good fuel
handling practices include bulk tank filtration, regularly removing the water
from the bottom of the storage tank and regular tank cleaning.‪
Where water contamination is a concern, equip the fuel system with a fuel/
water separator and service it regularly. Supplemental fuel additives designed
to disperse, emulsify or carry the water through the fuel system should not be
used, as they can disable or significantly reduce the efficiency of fuel/water
separators, resulting in fuel system corrosion. Since many fuel additives act
as surfactants, their effect on the efficiency of fuel/water separators should
be evaluated by ASTM D7261 test method, which is a quick measurement of
roughly how much water passes through a coalescing filter in a single pass.‪
