I use PS white year-round, dosing per package directions. That being said, it's pretty much just peace of mind on my part, to compensate for the reduced lubricity in ULSD and gelling in the winter. I think my biggest "insurance" in fueling is that I use the same local station, and have since the car was new. This station is not a truck stop, but does a very high volume of business. This isn't possible on trips, obviously, but in any case I have kept receipts from all fillups, so that I have a paper trail if there is ever a fuel problem. So far, so good.

NB: I change my own fuel filter, and have noticed zero water in the housing when I shine a light down in there. This last change, there was maybe 1/2 teaspoon of sediment particles on the bottom, which is all I've seen after 60K on the car— so I just ignored it.

Rico567: Same experience here with water in the filter canister. Anecdotal evidence abounds in TDIClub, saying the same thing.
Not sure where the water is going????
Also, ditto with the sediment.
I used OptiLube for a combined 230k miles or so, 4 diff CR TDIs. No issues, other than heated discussion with several esteemed TDIClub members

Fortunately the VW TDI filter sits in a warm location...then excess fuel (heated by the HPFP) is also routed back to the filter, this helps to prevent issues...both in geling and moisture.
The fuel and the filter both gets very warm...and this tends to "dry" out the filter in the canisters a bit.
On vehicles with a remote mounted filter (out of the engine bay) the filters tend to fill with water faster, and tend to get more waxes during the winter.
The water is still getting pushed through the fuel system....
In a truck big 100+ gallon tanks, if they are clean, and an anti siphon devise is not added, you can shine a flashlight and look into the tank...and see the moisture (assuming a clean tank) if the truck has sat for 6-8 hrs...but after 3-4 hours of running, the tanks typically will be warm to touch, and the water in suspension.
Additionally many HD diesel engines are fitted with a clear fuel filter housing...makes monitoring it very easy. I actually wish VW had them too.

I'll buy some. Didn't put any in my first tank, bit I'll buy a gallon or two and a smaller dosing bottle.

I think, for the most part, we have gone past the type of discussion of "my additive is better than yours" or "my non-additive is better than your additive", etc.

Personally the little inconvenience of adding it to the tank is compensated by the general peace of mind of insuring one of the most sensitive parts of a TDI, the fuel delivery system.

I've tried Pffp, Optilube and power service. They all seems to produce the same effect. Nothing noticable. Not saying that all fuel adds are created equal. You have your emulsifier, demulsifier, solubizers etc. that's all been debated here as to which method of water control is the best, which at the end of the day seems to be left to good old opinion. Some have more lubricity additive, but you can pick which one you want. You really want to just make sure you do not accumulate water in your tank for you lift pump to take a gulp of one day or to have water settling out to be left in your fuel system to cause corrosion. I look at it this way. I want an additive that takes care of water (if any) that has settled out in my tank. I also want to maintain decent lubricity. I found that what makes me feel all warm and fuzzy is a small amount of white power service (water control)and a steady diet of b2-b5. I really wish power service would make strictly water control and I would just use that and b2-b5. As for cetane, You probably will not notice any difference between running with or without. Your combustion cycle theoretically will be more complete with a higher cetane rating. If you put 2 ounces of cetane booster in tank. At least two things just happened. You feel better and your fuel burns a bit cleaner (theoretically. Higher cetane= greater combustibility?)For what it's worth. I still throw a bit of Optilube boost in every tank. I bought 3 gallons a few years ago and figure I should put it somewhere. I have never found any rust in the fuel filter housings of my vehicles so maybe what I am doing is working? I'm pretty sure I did not help answer your question one bit, but unfortunately there is no right answer to this one, other than whatever you use. Do not overdose. More is not better as it will end up in your oil and your engine oil does not like fuel additive in it. It has never happened to me but used oil analysis have attributed unfavorable results to overdosing of fuel additives in some cases. Just throwing some caution to the wind. Have fun.

What I do, because twice per year I drive 3,000 miles in 4 1/2 days I carry prefilled 8 ounce Kraft Salad dressing bottles with me. CLEANED out of course.

I put Silver PowerService, 2 ounces of a fuel pump lubricant or 2 ounces 2 stroke oil in these bottles and add one at each fill-up. Maybe that saved my bacon once years ago with my 2002 Jetta when I stopped to refuel in Outer Hicksville, Arkansas where an attendant put gas into my car. Car stopped after about 30 miles and had to be towed in. Fuel tank emptied and I was on my way. Got rid off the Jetta a year ago and still going strong.

Should you be concerned with cetane ratings? Probably not. But if you weren't a bit obsessive you wouldn't have asked the question.

I try to buy my diesel from busy stations or truck stops because I figure the fuel will be fresher. Other than that I don't worry about it like I used to back in the Evil Beetle days. Life is too short.

Well sometimes I wonder about the whole concept of the "freshest" Diesel?
I owned a 35' sailboat with a Volvo diesel engine. Every October we hauled the boats out and they wintered on a cradle, frequently in below freezing weather. Then in April they were dumped back into the water complete with a FULL tank of 6 months old Diesel.
Never a problem.

Diesel does keep for years if kept dry.... typical in drum or sealed tank.
Gas stations are not sealed tanks...they are open with lids that are semi ok sealing... slightly raised...ease of opening and refilling is more important. The tanks also have a sump system to collect water as it gets into the tank...
HD trucks with large tank openings are typically easy to inspect for coating that forms from growth...likewise the filters are in a clear housing. But boats with Diesel engines typicality have an extra part...a water separator....cars and trucks do not.
The idea if fresh fuel is to get fuel that has not had the chance for any moisture in it to grow algee and bacteria. Jet fuel typically has an anti icing/anti algicide/biocides called "prist" added, sometime preblended, Sometimes at pint of sale....

I think people obsess too much over "fresh" diesel. Although new cars are much more sensitive to fuel quality than older cars (or boats, Jetta_Pilot), they still can run on older fuel. My Mercedes (old) recently sat for 24 months before getting re-fueled, ran fine. And I have a B4V sitting in the warehouse (friend's) that hasn't been fueled since 2010. Also runs fine.

Question Too much fuel additive

I just got my first tdi an I wanted to clean the injectors an I accidentally put too much diesel fuel cleaner in my tank, I finished filling up and when I turn the engine on check engine light came on and it was the code p1248 what should I do. It didn't affect the way it's running.

No harm, no foul.

You can run it on straight cleaner...
Some mechanics fill the fuel filter with 100% PS...
Then they start up since they know it is mostly fuel...and filtered...and gives great lube.
Keep an eye out for the code...
Don't think k it's related to the cleaners.
