I also have the tank mod when I replaced my lift pump. It has been awesome and well worth the time.
Every other tank ATF sounds good to me along with the 2so.
37 gallons fuel.
10 oz 2so.
10 oz of ATF every other.
Does that sound about right?
Thanks again good sir.

I do 8oz ATF with 20~24 oz of the 2SO... my position there is if the ATF is reducing fuel lubricity, it should be offset with the 2SO. I add more just because oil is cheap, injectors are expensive.

For the past 180K miles or so, I've run 8oz ATF and 8oz 2SO. When I change my fuel filters, 20,000K, I fill the spin on filter with ATF and let it idle.

For now, I don't have enough data to determine the ratios above or frequency. I need a KISS system I do every fill up.

Hey everyone, I’m new to the 3rd gens, but I had a 2nd gen for about 11 years. I’m currently searching for a 3rd gen and trying to learn as much as I can.

This thread has been a good read but has left me with some questions. Mainly, I’d like to know about fuel system lubrication. On the 2nd gens a lot of us ran 2so with every tank. I ran about a quart with each fill up, every tank, for about ten years until I sold it. The main reason was to keep the VP44 healthy since it was fuel lubricated. From what I read, the VP44 was designed when LSD was available at 500ppm sulfur and when ULSD was mandated it cut the sulfur content down to 15ppm, thus killing the lubricating ability of the fuel (I’m sure you probably all already know this but I’m just trying to get where I’m going with my thought process). Seeing as how ULSD wasn’t mandated until 2006, was the common rail fuel system designed with the lubrication ability of the LSD?

I see that the ATF is a good solvent and it looks like many are using it with great results. It’s also been stated that it reduces the lubrication ability of the fuel, which was my initial thought when I saw this thread. Would it be beneficial to use extra 2so when running it to add back lubrication ability to the fuel, and then some?

As for 2so, would it be beneficial to run it, or some additive that adds to the fuel’s lubrication ability, with every tank to help keep the entire fuel system, including the cp3 and injectors, more lubricated?

Thanks for the help on this, I’m just trying to ensure that when I get a truck I can take care of it in the best way possible.

You can have my 3rd gen

Run the mix at the 8oz/24oz level and you'll be fine... my injectors have lived on this since they went in, CP3 is sitting at approx 270k now, injectors at 125k. CP3 has approx 160~170k on it since switching to the current mix.

Daily driven, rarely loaded, off road fairly often (up to the Covid issue).

I would also recommend using the hot shots stiction eliminator @ every oil change, 1 qt... unless your truck is loaded all the time, and then even then might be worth still using it. I found it resolved an oil usage issue I had where it was consuming up to 4 qts of oil in 7k miles. That was unstable oil usage meaninging sometimes it was 3, sometimes 4... after the SE use it dropped to a steady 1~1.5 qts over 10k mile OCIs.

Im curious to what a stiction eliminator could have done in a cummins..?
I believed my rings were stuck with carbon buildup and the SE helped to free them up. There was a noticeable change in the way the motor ran (remember back then power was reduced which made SOTP detection easier) as time went on. After the initial install usage started to drop over the next OCI, ultimately settling at a consistent (IMO) 1~1.5 qts. That first OCI with the SE installed usage was something like 3 qts over 10k (IIRC), then ~2 qts and then settling on that 1~1.5 qts over the 10k OCI.

Ultimately the only way to know would be to have 2 motors in a lab on a dyno and test with & without over an extended period, then do a tear down and inspect against each other.

Performance wise, at 448k miles, using the SE & the mix, motor runs awesome. Should also add, I believe I have a hurt cylinder compression wise that was measured with the injector install 125k or so miles back. That was before the SE usage.

Everytime i think i have this engine figured out... These odd ball success stories pop up.

Guess ill give this a shot too.

I think it would apply to a daily driven truck that rarely sees a load... There is enough feedback from those hauling loads that the issue I saw should not be a problem. For a long time the Ram was my only ride and it saw everything from short trips to long steady state trips. Those 2 conditions I think contributed to what I think happened.

Also, it has been mentioned that the longer, hard runs will make the motor run better as it is said to "clean out" the CC. I still see this occurring regardless of the SE or not. There is just no substitute for long periods of sustained higher boost levels.

Hey Steve, I've put about 600 miles on my truck since adding SE (at oil change). The sound from the engine bay has changed...its not quieter, but sounds more refined? Power while accelerating seems smoother somehow. I used to stay out of the skinny pedal for fear of what noises I would hear, now I find myself pushing the truck harder and listening really closely to try to spot odd noises. Happy so far, thanks for sharing your experiences and knowledge with us.

nice!! glad to hear! do you also use the atf/2so mix?

2so for sure, not sold on the ATF though. Even your pictures with the "volcanoed" injector tips looked exactly the same as my injectors I pulled at 220k miles and had a few tanks of injector cleaner on them

which cleaner?

those tips had several cleaners run thru them over the course of their life, only MMO & the atf made a solid difference in performance. Way way back in 2006, power service was good. then 2007 rolled around and they changed their formula for the dpf trucks. never was the same after that. of the 435,000 miles i have put on my truck, only the mix has performed consistsntly and kept injectors clean. 448k on it

I just dosed my first tank with the mix in the 5.9 and.........I dropped some TCW3 in my 95 Chevy 350TBI at a ratio of 1/500 to see if that helps out the crusty commuter.
Thanks for piloting the research on this Stevo5!

ATF & 2SO have been used long before I bought my truck, many others paved the way... It just took a long time for me to see the light and jump on board.

Remember, it is recommended to use the Dex 3/ mercon NON-Synthetic ATF with the TWC3 2 stroke oil...

Whats the reasoning for non synthetic?
trying to find stuff to answer your question & came across this...



It has been tried and true using the old dex/merc fluid, its been said the synthetic does not burn well and leaves deposits... was trying to find a pic of an example of it...

So the HotShots SE...are you just adding this to your oil? Do you have to back off of the oil qty if you add this? IE we take 12 qts of oil...if you run the SE do you back off to 11 qt of oil and 1 qt of the SE? Or just add it on top of the oil?

I don't see their documentation on their site.
