Have a long time diesel truck owner buddie that has informed me I should use water remover diesel additive often in the truck . I haven’t reviewed my owners manual as of yet but wondered what the consensus is on this.
The 2021 diesel suppliment has a few things to say on this:
- First, it says that if you are not using 'Top Tier' diesel then you should be adding a fuel treatment. Top Tier diesel is not available in very many locations, so you probably are not using it.
- Second, it says to only use AC Delco additive. But we know people will use other stuff and so does GM, so they give some guidance.
Presumably a water de-emulsifier is good. Such an additive will help ensure the water remains separated from the diesel and can be removed by the water separator unit.
I use Opti-Lube with every fillup which meets all of GM's guidance with the exception that it is not the AC Delco additive.

- Lubricity improvers are good
- No alcohols in the additive
- No organo-metallic compounds in the additive
- No water emulsifiers in the additive.

+1 for Opti Lube.

Anyone using Stanadyne Diesel Performance Formula 38566?
This is what VW calls out for my TDIs so I have a bunch of it. I've ran it a few tanks so far without issue this past winter since I've had issues with gelling last year in my Passat. Ill have to look at opti-lube but if I can keep using the Stanadyne I'll be set for a long time haha.

I use Stanadyne occasionally when I can find it. I mostly use Diesel Kleen which is available almost everywhere.
I use Diesel Kleen or Hot Shot's Secret EDT but not because of water. Additives to deal with water are unnecessary, the fuel filters have built-in water separators and there's a WIF sensor in the filter housing. If you're having problems with water in your diesel then an additive is not going to fix it. You need to be getting your diesel from somewhere else.
I use 2 different additives, every fill up - mostly for lubricity. We have 7 or 8 Chevrolet dealerships and 1 GMC dealership within a 40 mile area. I had called around to a few, and stopped by a few while out running errands, none had the GM recommended additive in stock - so I searched on this forum.
The consensus diesel additives have been Opti-Lube, Power Service Diesel Kleen and Stanadyne. I suspect they are all very good, it may come down to what is available in your area. Power Service is readily available where I live, and same with BG Diesel Fuel Conditioner (DFC). The BG DFC is more of a stabilizer, but also adds lubricity.
I use ~ 1 ounce of BG and ~ 6 oz’s of Diesel Kleen. I pour the BG in first, then the DK then I fill up my tank with Diesel to mix it all.
I use both every fill up and have been doing so for almost 2 years. I get what I believe is excellent mpg considering RTT, steel drive shaft and heavy E rated tires (lifetime avg is 22.9 - jacked up during covid, garage pull out & shut offs, as it was better prior), fuel filters life is ~ 38% at 21,500 miles and I’ve only been able to positively discern regen’s 4 times in 2 years.
Keep in mind it is possible to have too much additive - so reference the manufactures’ recommended additive to fuel ratio.
Below is my kit with additives, 1 quart of oil to have as a spare, Fast Orange and paper towels if needed. I load this kit before leaving for any out of town trips.

Not really sure if water separation additives are worth much as on it's own doesn't water, which is heavier and not dissolvable in fuel, naturally separate from diesel and go to the bottom anyway? I suppose separation "demulsifier" quality in an additive can't hurt though.
I like Optlube's "Summer" and use it year round. It does not claim water separation, but it has excellent lube, cleaning and cetane improvement qualities. My truck runs really smoothly on it, the cetane bump is noticeable. I fill up at a huge volume but decidedly "basic" diesel (Loaf & Jug) because I know the fuel is fresh and I get up to $1.05 off a gallon with their fuel points. Optilube calls for 1 ounce per 20 gallons minimum and 1 ounce per 10 gallons "premium" treatment rates. Naturally I go with the premium rate.
The OEM fuel filter system is not complex, the fuel goes into the filter box, which has twin top mounted (apparently 5 micron) filters mounted facing down inside, the fuel travels up through the filter, which presumably has a treatment on it's fabric to help to repel water. Any small amount of water that does get in should sit in the bottom of the filter box, where a water in fuel sensor is located. If more than a small amount of water accumulates, the sensor should detect it. If one got a really bad load of fuel with a significant amount of water in it, the OEM system should give a "ding ding ding Warning Will Robinson!" non dismissible hard message in the DIC, you know, the ones in the white box that mean business.
I have not had the misfortune of getting a WIF message, so just speculating. Have never observed water when draining the filter box for changes either. Because I was bored during COVID quarantine and am slightly insane, I did a little research and successfully integrated a 2 micron Racor marine filter in line after the OEM box, did a big thread on this board.
A cool thing about the extra filter is it adds another layer of water protection with filter media made for marine use - I suspect Racor's "aquablock" treatment on their filter media is good stuff, plus it has a clear bowl and is rated to 2 microns. To date have not seen anything visible in the bowl, it would seem the OEM filter system does a good job. If I ever do see any water or visible stuff in the Racor's bowl (seriously hope not and doubt I will) I will update the board.
The lift pump/system has not had any trouble as a result of the extra filter - it did not even register on the DIC filter life screen. Racor claims a .3PSI pressure drop on a clean filter, and with the OEM system in front of it, the add on filter should stay clean for a long time. Hopefully the entire exercise, which was done for added peace of mind, is a waste of my time, that would be just fine with me

Anyone have any opinions on this one?

REV-X Distance+ Gold Diesel Treatment. A lubricity replacement additive is a safe alternative to replace the missing lubricants in ULSD.

I use Diesel Kleen Silver in Summer and White in Winter mostly out of convenient. I would also gladly run Opti-Lube or Stanadyne if they were as readily available in my area.
Super old post (2003), but Diesel Kleen talks about emulsifiers, anti-emulsification, and Diesel Kleen in this post. Not advertising for them, just passing along information that was well presented (for me)

Does PS Diesel Kleen (silver) remove water?
This does not seem to have been covered recently (well I found nothing in the search). Anyways I always fillup at Arco with their ULSD ECD-1 and about 8 oz. or PS Diesel Kleen (silver bottle). I remember before people talking about water emulsifying (not sure if thats the right word) using...

Ah yes, I have seen the Netflix reboot - very cool. Waiting patiently for season 3, it is expected late this year
Opti-Lube every time I get fuel, has been since I got the truck last year. I have no idea if it's doing anything, but it's got good reviews online for actually doing what it claims to do. I'm happy with the performance so far, and the piece of mind knowing there have been engine failures related to stuck injectors. I run XPD in the summer and Winter formula in the winter. Gas mileage did drop a bit in the winter, but I can't really chalk that up to any one thing. Switching to Opti-Lube Winter, gas station switching to winter formula, switching to snow tires, or the engine running cooler and taking longer to warm up; any of these could have caused the difference.
