Water removal, yes....but Not all Diesel fuel additives add lubrication.

'bout all you can go by is the Spicer study from almost 12 years ago....1-10 = okay...13-20 actually lowered the lube rate.
I was using #4, but the supplier went AWOL, so....
I'm using a version of #6 now (2000 SUMMER blend, not tested)....probably the most economical to use....about 0.38cents per 30 gallons treated. 1/gal -> 4000 gals

The study was based on the worst case scenario on purchased fuel (like gasoline), where they obtained raw refined fuel (before the branding additive pack is mixed in) for testing.

Note: Bosch desired standard is 460 HFRR,
U.S. EPA standard is 520
Tested raw fuel (unadditized fuel ) was @ 636.

Infineum is a joint venture between XOM and Shell and is one of the world's largest formulators of bulk diesel additives. They publish an annual survey on winter diesel quality. US figures start on page 141. Short version is lubricity testing shows numbers below the EPA standard of 520 and cetane numbers in the mid 40s.

Page 23 in the trends section is worth a read.

A new term for me..... FAME diesel.

Bio?

What about 5% Biodiesel added? If you can find it.

 

IMO, Hook’ems link in his post #2 is more informative on what was tested good to use.
I think our concerns are USA’s fuel quality which we know sucks compared to other countries. where good lubricating fuel additives are a must.

I like Diesel Kleen with slick 50 and Cetane boost.
Lucas has IMO good lubricating and injector cleaning but that’s about it.

On my Dmax I tried both separately.
DK alone my mileage increased very little with cetane boost but the injectors had a little more clatter.
Lucas alone there was no mileage gains but the injectors was quieter.

I actually started to mix both back in 03, for me the best of both worlds, with a cost for additives at about 4-5 cents added to the per gal cost.

My previous diesel 03 6.0 PowerChoke had to be torn down a few times.
The diesel mechanic mentioned he hasn’t had any engines injectors as clean as mine was with my mix.
In Lake Havasu a good number of diesel owners use old grease, he’s found small chunks of chicken fat clogging the injectors.
Not a very good comparison old chicken fat grease mixed with diesel to a actual additive in diesel.

 

what are your thoughts on this?

5 Best Diesel Fuel Additives of 2019 (And Why They Are Worth Buying!)

 

#1 should be #10 or higher.
Lots of people like and use Opti-lube
I use DK and LUCAS
The others I don’t know.

 

I've used OptiLube every other fill up since using Propel Fuels instead of Diesel #2. I've tried Biodiesel, but it smells.

 

Been using Archoil AR6200 for the past 4 years religiously. No complaints here.

 

what's wrong with Stanadyne?

 

That’s what I use but I’m finishing off a gallon of opti right now.
Just recently seen Stanadyne XL? ,purple on the bottle.There saying ,2 people here,it’s better ,I guess better than lubrisity is what they were saying.
I wonder if this new XL is marketing? 'dunno;

 

I use opti-lube purple every fill up. Its strictly just for lube. I use to run the red XDP, but the purple is cheaper and brings the scar rating down even more. Could be mental, but I swear my truck seems smoother on the purple vs the red.

 

As far as Stanadyne goes... That particular list has the performance formula as 1. IF your looking for straight lubricity help then I would assume the Lubricity formula would be your better choice. The Spicer test although outdated at this point in time, confirms that, and in that specific test performed what I would consider above average. As mentioned the top 9 additives all increased lubricity. Before anyone jumps on the outdated comment, lets face it, most, if not all of these additives have changed their products since 2007 to account for ULSD we now use in the US.

157 vs 50 micron improvement lubricity vs performance formula.

I do know the Stanadyne formula has changed to now support up too B20 (when Spicer did their test it was B5)

as far as solvent wise in the mid 2000's, or if 12 years later they do or do not use it any longer. I'd like to think they would have exhausted that particular supply long ago in production...

I did read alot about solvent and DPF issues back then (mid 2000 era). In practice (my own experience) I had no issues while using stanadyne products and DPF issues.

On my current 2011 LML I use Stanadyne Lubricity in every tank with just shy of 90K at the moment with no issues to date.

Stanadyne Diesel Fuel Additives are approved by major vehicle manufacturers including Ford, GM, Navistar, Deere, Caterpillar, VW, AM General, and Volvo Penta.

No I'm not a salesman but I have done alot of research as well! this is my OPINION of a product and first hand use in Pickup trucks, and agriculture equipment.

I certainly don't discount DRC opinion as well... he's a smart man and great contributor here!

 

....have changed their products since 2007 to account for ULSD we now use in the US.

The EPA rules on ULSD vehicle compliance went into effect at midnight on 12-31-2006.
It wasn't a surprise that just popped up one day, leaving additive mfr's at a loss of how to comply with the future of Diesel in the U.S.A.

 

my line of thought is not that is was a surprise to the additive manufacturers.

Its along the lines of, as with any evolution of any product, the additives have gotten better at "lubricating" this ULSD. Or removing deposits, emulsifying, and so forth....

Additives today, I can promise, are not the same formulas, and have evolved to be better products due to longterm research and testing over the last 12 years.

I am sure the SPICER test repeated yield different results today due to this research.

Maybe.....it's been a while since the study.
Or not
What would be their ROI? A feel good feeling of knowing their product has improved?

$$ profit is the driving factor on whether any improvements are made to a product that's selling fine as is. No?

While we in the Diesel community know of the Study, that's a small fraction of the total number of Diesel owners out there.
Marketing would be what owners see, or are pushed on 'em, as the next great thing to buy and use.

Another study would be nice. Probably will never happen after all the BS the 1st time around, from all of the naysayers alleging corruption and bribes on their findings.

It was almost as bad as all the 'hoes coming out of the woodwork over the Judge Kavanaugh hearings. :teehee

 

Bringing up the manufactures approving Stanadyne brought back memories.
My GM dealer was very negative about customers wanting to use diesel additives in 07.

But if you insist on using diesel additives you’ll need to use GM’s diesel additive we have it available in our parts dept this way you won’t void your trucks warranty. 'uhNo
Of course at a premium price.
Who supplied and bottled GM’s diesel additive, Stanadyne. :surprise:

 

There’s plenty of different additives available that people like and suggest.
About one year ago I was mislead a little with trying Amsoil fuel treatment with cetane boost.
A little pricy but I figured what the heck, besides it’s in a nice skinny 16 oz bottle.
No gains, no loss, it’s not worth the pricey cost, especially when I always get a warm fuzzy feeling using DK and LUCAS in every tank.

 

LOL Hook... Kavanaugh... Good one.

and yea DRC I remember that quite well also back in the mid 2000's. My Local GM dealer was the same way about pushing the GM additive... Made by Stanadyne.

certainly alot more selection and easier to obtain diesel additives today then 15 years ago also...

every store has a selection.

Not totally off topic but the Power Service Products that are now in partnership with Cummins. for Lubricity and fuel cleanliness as they state...

I have used the Power Service Diesel Kleen products for BIO issues in my Agriculture fuel tanks that may sit for a time...

I read an article how Power Service declined to participate in many Lubricity tests and assured customers they did their own, far more robust, testing year round. They did not like the tests that only ran a few samples as the average would be extremely low. And according to them they have found significant differences in fuel in area's of the country etc as we have all read about... so anyway... heres to hoping the additives help my CP4 continue to be happy. Least until I have enough money to go to the S&S 50 state emissions CP3 conversion.

Cummins likes some Power Service

https://www.equipmentworld.com/for-...ld.com/for-first-time-cummins-recommends-fuel-additives-for-its-diesel-engines/

 

they have found significant differences in fuel in area's of the country etc as we have all read about.

While some go to the center of the Tootsie Pop and read just the numerical ratings listed, the study was based on RAW ULSD, before any lubricity packs were added to the fuel. Samples were obtained off the retail shelf, with the exclusion of the top OPTI product, which at the time was new and not fully available on the market for independent buys.

This ruled out differences found throughout the Country, and also addressed the worst case scenario of pumping Gasoline instead of Diesel fuel.
So if you choose one that lowered the HFRR to below 460 on untreated raw Diesel fuel, you're pretty much GTG for protection. :thumb

 

rox5488,
If you don’t have a liftpump, have you considered investing in one.
Even with a stock engine it’s a wise investment, having the extra filtration is a plus.
Kennedy, AirDog 100 or FASS 95 is all you would need.
I don’t know the Kennedy kit numbers, that’d be something hook knows.

On the AD and FASS what fuel is not needed to Getty-up-n-go returns back to the fuel tank.

=============================================
Do I understand you correctly that a lift pump ( which presumably includes additional filtration) is the answer to the risk of CP4 failure?

What do we know statistically - have CP4's "gernaded" in Duramax trucks equipped with a lift pump?

(as many of you in here know, I (along with several others in here ) are satisfied that at best, GM's decision to keep using the CP-4 is nothing more or less than fraud - consumer fraud. I have signed on with a law firm in the hopes of getting my money back for the approx. four grand for the CP-3 conversion.

Simple fact...word is out that the LML's can cost you about ten grand because GM thought it was "cute" to keep making trucks with the CP4 when it knew better.

So, with the "word is out", go try and sell a LML at ANY price, unless you can prove it has the CP3 conversion.

 

I fingered that, I just wanted to get ur info out there.

 

Well, I guess I will give the history lol. Bought the truck Jan 2014 with 60,000 miles on it. Soon learned about the potential failure of the CP4. I used Stanadyne Lube Formula for awhile, then in 2017 switched to Opti-Lube XPD, and recently I have been running only Opti-lube XL because it is the best for lubrication. I have an AFE lift pump but actually didn't install until about 160,000 miles. I made the decision to add a lift pump because I saw evidence of sucking air when under a heavy load (idle FRP would be fluctuating a lot after towing). Since the lift pump install, I have not seen any fluctuation in FRP at idle after towing. I constantly watch my FRP vs Desired FRP and it is always within 100-200psi. I change my fuel filters every oil change which is about every 10,000 miles, sometimes sooner.

 

It’s not just the fuel, air, and lubricity, they didn’t devise a way to keep the plunger or some other part from rotating in the housing. Now it could be that bubble of air causes enough of a low pressure on one side to cause the rotation and catastrophic failure.

 

I think i will continue to use BIO as my additive. I am new to the LML world, and probably would not have bought the 2013 LML after reading about the potential CP4 failues. I am NOT new to Diesels as i had a 1995 Cummins that loved BIO even up to 99% in the summer months. It would run smoother, quieter and smelled better burning BIO than anything else. With 260k plus miles with zero issues on BIO.
Read this article https://www.biodiesel.org/docs/ffs-performace_usage/lubricity-benefits.pdf?sfvrsn=4 about bio lubricity and find some B2 or higher for your truck.
I did some research and seems GM is ok with as much as B20 even in the LML.

I just found a supplier here in OHIO that has B99 for $0.37 less than std diesel. Drop in one gal in a fill up save $0.37 and have about a 3% mix or 2 gal, save $0.74 and have a 6% mix.

Hope i am allowed to post the link.

Hotshot LX4, its made for the CP4 issues.
