With the recent thread here about injector issues on '06's I was wondering what to do.

I run Stanadyne performance formula in every tank and was wondering if I should add some World Lubricity Formula as well?

TIA

 

What where the 06 injector issues?

 

stanadyne performance adds lubricity but i think the lubricity formula adds more for low quality fuels.

I'm referring to this thread.

Although I must admit I was a little confused by this thread and didn't fully understand it, it seemed to focus on the injectors.

 

Gottcha......

 

Standadyne's lubricity formula has 4x the lubricity of their perf formula. But without re-opening the debate, I think using Stanadyne is stupid because it's a demulsifier, which does not work in dynamic environments like a truck's fuel tank that sloshes. Easily evidenced by the lack of water when draining the fuel filter housing.. It makes much more sense to use something with a solubizer/emulsifier, like Powerservice, Redline, or Primrose.

 

I have added stanadyne PF formula or primrose 405-409 since day one in my truck,no injectors issues yet.I have over 40,000 problem free miles on the OD.coobie

 

Stanadyne and Primrose take exactly opposite approaches to water dispersion..pick a camp coob!

 

I like using both,no fence walking here,heck sometimes I use a shot of marvel mystery oil to boot coobie

 

Stanadyne appears to be the only fuel additive that has OEM endorsements, multiple endorsements at that. I've heard that they make the Ford fuel additive too but haven't been able to confirm it. I suspect that OEMs much prefer demulsifiers, which also seems to be the case for marine diesels, although you'd think otherwise considering how much water they're exposed to.

I like the idea of a two stage system, using a demulsifier with water separaters and then perhaps using a emulsifier in the final stage, but since they don't appear to make such a thing I'll stick with a demulsifier as I don't want unlimited amounts of water getting into the fuel.

Draw your own conclusions.

 

My conclusion is all of this stuff is snake oil. My truck runs great at 47K on it right now and I run none of the above. Just good ole #2 diesel, like the owners manual says.

I have tried some additives a couple of times and could tell no difference. I am not convinced that they do anything other than make the buyer FEEL better about it.

 

Can you explain this in leyman's terms?

Are you referring to Stanadyne performance or Stanadyne products in general?

 

The water is already in the fuel - it's present in all fuel. Demulsifiers are actually a great idea in a static environment, such as in a stationary fuel tank, or in tanks at stations. The problem is that once it's introduced into a dynamic environment like a truck and sloshed around, they simply aren't powerful enough to keep the water separate. So considering the water will be in suspension anyway (try it yourself with a few drips of water in fuel in a jar, shake it and use stanadyne), the question is how big of water particles do you want to pass through your fuel system, as they will do so inevitably. The stuff like powerservice (far and above the best selling additive), Redline, FPPF, Primrose, etc...will make the water either solubize (dissolve into the fuel in layman's terms) or will break it down into extremely tiny droplets that will more safely pass through your system.

My mercedes diesel owner's manual says right in it they recommend Redline, and this emulsification theory is certainly backed up by the fact there is no water separator whatsoever, just a spin on fuel filter.

Lancek - I was referring to the performance formula. Products like stanadyne's lubricity formula do not disperse water (as far as I know), nor does powerservice diesel kleen, and a few others.

 

"My conclusion is all of this stuff is snake oil...."

If you are always blessed with good fuel, don't run into a cold snap, then you won't need the stuff. I notice that the engine runs quieter in cold weather with a fuel additive, evidently due to the increase in cetane. The fuel injection in our newer generation trucks seems to 'go back home' and act like the older generation trucks in colder weather while warming up and under high loads, where they start rattling a lot more, and a cetane increase seems to help.

Awhile back a number of people in Canada were complaining about lift pump failures, above the usual failure level, which as I recall might have been due to some bad fuel was being sold for awhile. In a couple of threads I asked if anyone wih failed pumps had been using a fuel additive and no one replied. A fuel additive won't prevent a bad design from failing, some of the lift pumps were failing due to excessive idling ?, it won't conteract all cases of bad fuel, but it does work as designed for some situations.
