Anti-gel over kill?

That red fuel is the best lol.

 

Another thing to consider is underhood temperatures. Your tanks of #2 might be fine, but the weak points are really where the fuel volume is less. Filter, filter housing, fuel lines. I had a freeze-up in Rutland VT running around in -5F temps. Winter blend #2 plus Howes, and the filters and lines gelled hard. Wasn't running a winterfront on my Star. Road repairman that came out had a slick rig in his service van...a heated diesel tank, a pump and a bunch of fittings. He pushed warm fuel back through the lines into the tank, and told me in no uncertain terms to get a winterfront and ditch the Howes. Put one on, and never had another problem with temps down as far as -25F. I never did buy another bottle of Howes, either.

 

You gelled up when you were driving down the highway or parked overnight?

 

I have nothing good to say about Howes.
1981,north Dakota- 35 temps.
Was thinking I should put more additive in the tanks.
Went in the side box to grab my last bottle of Howes and it was like jelly.
I would like to think they changed their formula since then, but I'm not taking the chance.

 

Howes does get cloudy when below freezing temps. I have couple bottles sitting in side box in winter and they'll get all cloudy below freezing.

 

Fuel gelled up while using Howes two years ago . It did happen after sitting for the night . NOT fun . NO more Howes for me !!

 

I've had Power Service sort of fail following an overnight engine off (APU) where the temp dropped to 5f with treated Missouri fuel. Lost power on hills and overpasses but made it to a truck stop to get another 80 gallons of fuel and another dose of Power Service, and 15 miles later, problem solved. That's where I began to add more then the recommended amounts when temps go low enough for me to want to treat.

 

An inexpensive and easy/instant test kit to test fuel quality (cold temp properties) at the pump would be sort of good. No need in treating perfectly good fuel that's tested good down to xx degrees

 

Not sure if true or not but heard that if you use too much additive , it can have an adverse effect and block filters . Again, not sure if true or not .

 

I have the probe for fuel temp plumbed into the fuel line coming into the first fuel/water separator. If it's going to be stupid cold I wrap the filters in something to insulate
