Duelly Dad Last summer I was using Optilube summer+, when I ran out I bought Shaffer. I’ve ran it with out and you can definitely tell The difference in the noise level with out the Shaffer’s in the tank. I’m a firm believer it’s going to extend the life of my 18 Ram so every tank it get 2oz of Shaffer lube additive.

SyN Years ago with my 01 Ford 7.3L PSD I always ran a high quality synthetic 5W-40 HD oil w/Synthetic media oil filter along with 8K mile OCI.
With every tank of diesel fuel - I added 6 to 12oz of either Schaeffers diesel treat or Red Line 85Plus. (Depending on how many gallons of fuel was added).

At the 296K mile mark I was still running with the 1st set of OEM injectors!
I am a very much a believer in a well thought out OCI & a very high quality diesel fuel additive! Sold her @ the 298K mile mark!

I am now using Schaeffers Diesel additive (SoyShield) within my new 2017 6.7L CTD.
When I can use discount coupons codes on HSS - Every Day Diesel & Diesel Extreme I dam well take advantage of it.

When used @ the proper dosage: (These) fuel additives are reasonably inexpensive - especially when compared to Cigarettes / Snuff / Alcohol / Drugs / being bought by owners every second of every day.
The annual cost of any of these 4 addictions - makes my tiny diesel fuel additive addiction totally irrelevant! (When a conversation of Waste of $$$ all the sudden out of the blue spews out)!

Anecdotally, I spent the first decade of my adult life as a metallurgist at Allied Signal, and worked below a chem lab, so I find tests like this to be fascinating and highly informative. Thank you. Additionally, my father was an engineer too, and introduced me to diesels when he brought home a new 1984 3/4-ton Suburban with a 6.2L N/A diesel. That one lasted nearly 300K miles towing horse trailers interstate to horse shows. It was retired in 1992 and sold around 1998. The reason it was retired is because it got replaced by a 1992 Dodge Cummins intercooled turbo diesel (he raved about the new intercooling), which was the primary horse hauler until 2010. Dad was a big proponent of diesel additives. He'd occasionally run a slug through to clear out water and clear the injectors. Our rigs lasted decades, and as a result I'm a believer in proper additives.
I found many of the posts in this thread helpful. But honestly, this one grabbed my attention. I trust the guy that bought a diesel 'burban back when the rest of the U.S. auto industry was in tatters.

All we really need from the fuel companies is 2% bio-diesel added to regular diesel. That gave the best results. I wonder if 2% did so well, why not 10%. I wonder how 100% bio diesel fares on the HFRR test.

AMS oil sells diesel additive and suggests 2SO is probably safe.

Here is a SA study says adding 2SO is not helping. I can see if 2SO also has zinc-metals might hurt the fancy emission equipment.

Add some acetone to it!

Gator1 ATF is amazing, we used to use a 50/50 home brew of atf and solvent on the cutting tools in the machine shop it really made the tools last a lot longer and kept the tool and part from getting hot.

sdowney717 I like the idea of adding two stoke oil and or ATF to diesel. ATF is a 10w oil, and will easily mix with diesel. I am thinking, at the pump put the oil in a gallon container, fill with diesel, shake it hard, then dump into the fuel tank, then fuel the truck. This will help mix the oil into the fuel.
The benefit is keeping wear at lower levels, and a smoother running truck for some people. For them with smoother running engine, it could be their fuel system has some wear causing parts to stick a little.

I have run ATF, even 50-50 in old engines and it helped to clean out the carbon and sludge and also cleaned the rings. I ran ATF in the crankcase for about 50,000 miles in a Saturn SL2, then when oil burning got too bad, took it apart and the pistons and rings were clean, and still had cylinder cross hatches. Reason for oil burning was worn valve seals and weak rings. There was no bearing wear, the ATF had no negative affects.

Gator1 Ya, I have living proof today's low sulfur diesel is killing our trucks with insufficient lube in the fuel drying out the seals and killing pumps. I have a 10mm stroker pump less than a year old with very low miles that started to leak from the back cover, soo I bought a new oring kit just in case it got worse and someone mentioned to me to try adding some oil to your fuel. So I picked up a gallon of 2SO and dumped it all in last time I filled up, and would you believe somewhere around 1/2 tank left the pump dried up and stopped leaking! It also seems to run a lot quieter from the injectors to the IP and all the way back to the lift pump just seems quieter.

THE RESULTS:
These results are listed in the order of performance in the HFRR test. The baseline fuel used in every test started at an HFRR score of 636. The score shown is the tested HFRR score of the baseline fuel/additive blend. Also included is the wear scar improvement provided by the additive as well as other claimed benefits of the additive. Each additive is also categorized as a Multi-purpose additive, Multi-purpose + anti-gel, Lubricity only, non-conventional, or as an additive capable of treating both gasoline and diesel fuel. As a convenience to the reader there is also information on price per treated tank of diesel fuel (using a 26 gallon tank), and dosage per 26 gallon tank provided as “ounces of additive per 26 gallon tank”.
In Order Of Performance:

CONCLUSIONS:
Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association. Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel. Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated. Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

CREDITS:
This study would not have been possible without the participation of all companies involved and dieselplace.com. A special Thank You to all of the dieselplace.com members who generously donated toward this study and waited longer than they should have for the results. You folks are the best.
