FWIW - found out some info from Howes tech and Power Service tech about thier additives and gelling. Both have very simular info regarding ULSD -
1. Too much of an anti gell additive can acturally have a reverse effect. No more then 3x the bottle recommended amount (follow bottle directions). 5x will start reversing effects. Will not harm the fuel system, may smoke - but in sub cold weather, fuel will jell just like regular #2. In Minnesota, from our refiners, streight #2 is good for about 10°F for Cold Fuel Plugging Point - all states very in their gelling temps as to a fuels CFPP.
2. ULSD contains more water (molicules) then past diesels fuels. Their have adjusted their anti - gelling additive pkgs to help battle this. Makes it harder for the additve to do it's job. Sulfer helped tie up water and move it through the system.
3. The addition of BIO or soybean oil to diesel (B2 - B20). The more bean oil, the more treatment neccessary - TOO A POINT. B2 requires no addional additive then #2, B20 requires a 3 x amount of regular recommended amount. Again, 5x treatment rate will cause a early jelling effect like plain #2.
4. In extreme sub-zero temps, a mix of 20/80 #1/#2 and additive is suficient. (Not talking Alaska or northern canada here - primary states). #1 is very dry and as you all know - dry isn't good for the fuel system.
5. Both companies like to inspect fuel filters when someone crys gelling - they both found the primary issue is moisture plugging the filter, next is bacteria or junk (dirty) due to cleaning effect of bio and/or additive pkgs and last is actural gelling - some of which is caused by too much additive. Opinion is, some guys just have poor fuel system (filter) maintinance habits. Northern states have less gelling issues then mid-states.
6. (sub-zero temps) Stoping air flow into the engine area - keeps heat there. Truck idialing can pull in cold air and push heat out of the engine area.
