Fuel Additives?
What's the consensus on this one?
Should I be using a fuel additive to help with lubricity/injector yada yada low sulfur diesel?
If yes...what kinds do the people here use?
i've seen something called Stana... something in a couple threads.
Gets pretty cold sometimes....maybe it will help to keep cold weather fuel problems from showing up as well?

For severe cold weather, #1 diesel would be my choice if available. If you encounter gelling problems, FPPF Meltdown is good to have in your emergency cold weather kit, along with a spare filter, gloves and wrenches.
As for ongoing fuel treatment / lubricity - I like HOWES, which is available at most truck stops.

I have used the Stanadyne Performance Formula since the beginning. Back in the middle of 2007 I read a Lubricity Study on some of the leading fuel additives Stanadyne included, and while it did OK it was certainly not the leader of the pack when it comes to lubricity. So, I started adding the Stanadyne Lubricity Formula in addition to the Performance Formula. I feel much better using this combo since the low sulfer diesel showed up.Originally Posted by Knuckledragger

FPPF Total Power is the best that I have found.
As Mark stated Meltdown is handy to have for Emergency use. We stock both.

I use Stanadyne also, but for commercial products opti-lube XPD has the best lubricity according to this test
http://http://www.johnfjensen.com/Di...itive_test.pdf
I have not been able to get my hands on the opti-lube though.
The test shows a 2% mixture of 100% bio-diesel to be the best for lubricity, but bio-diesel gels at about 28*F

John: I know this has been asked before, but, does FPPF allow your filter/separator to remove the water from the fuel? Does Howes? How do you tell, from reading the labels, or looking at the adds on the computer, what properties to look for. IE, total emmulsification, or total dispersion, etc. ? I can never remember. Seems like I read somewhere that Stanadyne just breaks up the water and allows it to pass on through the filter media, to be injected and burned. Is this so, and if so, what's the difference between this and immulsification?
Thanks,
Dick
