Curious as to what the majority is using for a conditioner I know that the party line from GM is an water separation agent but I get the feeling that most people are using the opposite.

I use John Deere Winter formula since its about the only thing I can find within 100 miles. It is quite close in composition to standyne.

Stanadyne Performance Formula for me :ro)

Primrose 409 and 405. have also used fppf but idle seems a little smoother on the primrose

I have not uesed any conditioner. Have 58700 miles change filter every 15M and have not seen any signs of water or had any problems.

FPPF Total Power

Currenty trying RBP's (Rolling Big Power) High Performance Diesel Additive. This is what it claims:

" 5% Cetane Gain, Increases Horse Power, cleans diesel fuel build-up off your injectors and lubricates them. This will also increase your fuel mileage. If your fuel mileage is low; It is most likely due to your injectors.

Water is welcome almost everywhere-except in your diesel engine. Water in diesel fuel damages injectors, corrodes tanks and fosters the growth of bacteria. Our highly-concentrated Diesel Power Additive removes unwanted water to protect your engine and keep it running smooth. Diesel Power is also an all in one package which contains lubricity. Increase your engine's performance by giving Diesel Power a place in your engine today. "

LATER!

I use Stanadyne if I use any http://www.dieselplace.com/forum/images/smilies/smile.gif

Stanadyne Performance Formula

Just to play it safe I use a Emulsifier and a Demulsifier..:eek:

No, I use FPPF........

Soy Shield Winter & Summer

I'm surprised that it is close to a 50-50 split. I expected it to be swayed one way for sure.

I used FPPF, Rotilla DFA and Power Service and I can't really say I have seen any performance differences and I have never seen any water or rust in any of my filters and I have cut them all open just for fun.

FPPF mixture or aka kennedy's cocktail

PS every tank, PS911 once a month.

Been using FPPF in every tank since just after buying the truck.

Stanadyne the RUST maker.........

fppf/Kennedy cocktail, change fuel filter 7-10,000 miles

Not familiar with this "cocktail" a few of you are speaking of.

Primrose 405/409 since new.

Primrose 405. Started with Redline 85plus, also an emulsifier, but switched a year and a half, or so, ago. Runs great at 45k miles.

I have used stanadyne, powerservice, fppf, and on occasion other "non-alcohol" winter fuel treatments. For the rest of this winter I'll be using primrose. I have had good results with all of them although for some reason my winter fuel economy is less impacted by stanadyne than the others.

Kennedy cocktail. FPPF Total Power/Cetane8+ every tank.

Steve

Schaeffers 139 SOYSHIELD anbd FPPF.

Stanadyne Performance Formula for me :ro)
Ditto.

Stanadyne PF since 5 miles.

ps.... its easy to buy almost anywhere wal mart, atwoods, loves etc.

Nothing except #2. It seems to me it doesn't make a hill of beans what you use. If a part will fail, it's going to fail no matter what snake oil you use. I would proabably use a additive if I lived in a colder climate, though. Not a real issue in the Gulf south.

i use holmes, but i don't know if it's an emulsifier or demulsifier...the shop foreman advised me to use it...it's not a $stealership, and they sell lots of different additives...

FPPF Total Power.

another vote for the Stanadyne PF here......62K miles, no problems so far

John Deere winter formula.
