Autozone has 3 formulas: Performance, lubricity, and injector cleaner. It looks like the lubricity formula treats twice as much fuel per bottle.
What flavor of Stanadyne should I use?

whatever makes you feel better 
honestly, i wouldn't bother. i personally barely ever use additive. i tried to make a point of it years ago but could never keep up with it. i keep meaning to, but life is busy.
although i barely use it, what i do is buy a big jug of power service, a big jug of ashless 2-stroke oil from walmart, mix 50/50 and add 8oz per tank -- after getting home from a recent fillup. it's silly to cart around bottles and stuff to put it in *right* at a fillup. madness!

I use the injector cleaner 1x every 3 mos. Performance or Racor every fill up other wise . Once in a while I use TWC-3
Past 4mos I have been using Murphy diesel exclusively. based on their cetane rating.
Truck & Jetta like it

If you don't have B5 where you live then lubricity additives are a good idea.

I use the Stanadyne lubricity in my 13 Jetta and 2001 cummins love it

IMHO,
The best diesel fuel additives (for cleaning and mileage) use Naphthalene. These include:
Motul Diesel Fuel System Cleaner
Total (no longer available) diesel fuel additive
Starbrite Star-Tron Diesel Fuel additive(West Marine, Walmart)
Optilube XPD
These products do not use any Naphthalene (to the best of my knowledge) and I've never noticed any difference and don't use them any longer:
Power Service (all types)
Stanadyne
Diesel Purge
In looking at the MSDS for the fist set of products, most of them list 66% or higher content of Naphthalene. For the others that don't list Naphthalene, it is possible that they are included in the Aromatic Hydrocarbon category. I'm just not sure and some of the manufacturers try to hide their forumulas.
Of the three in the non-Napthalene category, I always thought the Stanadyne was the better of the three, but not as good as the Motul or Star-tron.
I haven't used the Optilube....yet. But I will be placing an order soon.
This is based on my use of these products over the years of owning my TDI, FWIW.

I agree on your opinion of the Power Service. I've tried them all.whatever makes you feel better

I've been using the all season performance formula, it seemed to be the best all around formula that Stanadyne had. I've been considering using the Lubricity since that's most of the reason I even use an additive, I just liked that the one I use since it seems to have all the bases covered. For those of you who have run both the Performance and Lubricity formulas, have you noticed any difference between the two?

Interesting. Do you have any links to information regarding naphthalene?
I have the same mindset as you. I was thinking of using 3/4 dose of performance and 1/4 dose lubricity. I don't think I will ever notice the difference an additive makes, but I use it for peace of mind.

After I posted this info, I googled "Naphthalene as a diesel fuel additive" and found that moth balls made from Naphthalene are 99.5% pure.
And then was reading about people using it in gasoline and diesel fuel.
Just try this: put in your Stanadyne additive and go for a drive. Then get some Star Tron from West Marine and put that in your tank and do the same test drive. You will notice a difference, and it's not a placebo affect.

Tongsli: Flyingtoaster is driving a 2015 CR TDI. You are driving highly modifies pre-CR TDIs.
I'm not sure your advice applies.

I alternate between Performance and Lubricity. Haven't noticed a difference, but wouldn't expect that I would switching back-and-forth with every tank.

Well then he can keep using the Stanadyne. Last time I checked, it didn't say only use on VE ALH engine on the packaging.

I'll probably stick with what I'm using with winter on its way. I do occasionally run a couple tanks with nothing to make sure the concentrations don't creep up. If you run your tank down to 1/4 and fill up again you still have 1/4 dosage in the tank. Adding another full shot of it will just continue to cause the concentration to rise. I don't like running the tank down to near empty to eliminate it so it's either run a tank without or add less at the next fill up.

I like the idea of using an additive I can actually feel the difference with, but I feel safer using a high volume brand sold at Autozone. They may have switched from Naphthalene to make the additive more compatible with newer diesels. It is not an expensive chemical like moly.

Motul, Star Tron and Total and I suppose Optilube have been making their products since I bought my diesel in 2000. Well before the newer diesel engines.
Just passing along my experience, FWIW.

I think maybe what he was getting at was that it's possible Naphthalene containing treatments have an negative effect on the newer emissions components such as DPF's and that this could be why the newer products which specifically state they are safe for those components do not contain it. That was the take away I got from what he said, maybe I'm wrong.

In this case many of the current highly used diesel additives in our TDIs with DPF should not use them? Take for example Opti-Lube XL. According to the MSDs it has up to 28% of 'Petroleum naphtha' (link):
Comp CAS No. Percentage (by wt.) Carcinogen
Petroleum naphtha 64742-94-5 From 19 to 28 percent N/E
Another well known additive would be Amsoil Performance Concentrate – Diesel Injector Clean which could have as much as 70% 'Solvent naphtha' (link):
Name CAS number %
Solvent naphtha (petroleum), light aromatic 64742-95-6 30 - 60
1,2,4-Trimethylbenzene 95-63-6 10 - 30
Solvent naphtha (petroleum), heavy aromatic 64742-94-5 5 - 10
My counterpoint is: wouldn't using such diesel additives (and similar) help our modern diesel engines with DPF burn more efficiently and cleaner and therefore actually lessen the load of the DPF?

I don't know, I was merely giving my take on his quote. I'm in no way arguing with you. Volkswagen also takes the stance that they don't approve additives for use in these cars don't they? Why is that?

^^^ VW 'does not approve' ... or ... 'remains agnostic' when it comes to diesel additives for TDIs?

I believe it would be "not recommended."

First, what Vatozone in SoCal carries Stanadyne? I've checked a half dozen of them in my area and none of them carry it.
In any case, I order my Stanadyne online and use the performance formula because I want the cetane boost as well as the lubricity improver. I know even under the most optimistic estimates of MPG gains I'll not make up in fuel savings what I spend on the additive but I figure I'm already spending the money on an additive and if it extends my time between fillups even one day it's very worth it.
I thought it was "does not recommend" which is actually a bit different from "not recommended"

Both of the Autozones in Rancho Cucamonga have Stanadyne (including the larger size of Performance) and Power Service, among others. There is a 24 hour store on Foothill near Archibald.

OK thanks, I don't get out to the 909 too often, will try to keep that in mind the next time I'm out that way.
