Runaway DIESEL! - 5.9 Cummins Has Developed a Problem 

I worked at a Dodge dealership back in mid to late 90’s and when we changed fuel filters on the 5.9 Cummins we always filled the filters up with atf. 👍🏼

I love the content man! Your videos with the Black 6.7L Powerstroke helped me when my Dad sold his 2019 Ford F-250 Lariat 6.7L Powerstroke deleted and tuned for a 2021 Ford F-150 Ecoboost. He bought a 2022 Ford F-250 King Ranch 6.7L Powerstroke yesterday so I am relieved from my pain. Love the vids! Keep it up!

I’ve worked on heavy equipment for years and we always refill fuel filters with atf especially out in the field when we change filters.

Its amazing how many people out there have no clue....I've got a 2001 7.tree with 800 thousand miles all original everything...still stroking to this day....I've added ATF,15W-40, PURE SYNTHETIC LUCAS, USED MOTOR OIL,2STROKE OIL, HYDRAULIC FLUID, Kerosene, been driving it for almost 24 years now......she will still outrun any dodge or Chevy....

*Does it have detergent" Have you ever seen a dirty transmission 😂

I would run 16 Oz of tc2w ashless 2 stroke oil fom wallow in my old 2006 5.9L. Smoothed the engine out compared to when not running it.

I run lots of equipment, when I change the filters out I prime it with ATF. Keeps them all running clean.

Diesel is basicly a thin oil in a way so yes oil and diesel do mix, a lot of guys pit atf in there diesels I also use 2 stroke oil sometimes as an injection lubricant never had an issue

I've fixed multiple duramax injector balance rates with liquimoly diesel purge. I'll run the truck straight off of it though, no mixing. I use it to clean out TDI injectors aswell

Had an old friend years ago that ran big diesel trucks hauling grain , and he swore by atf in each tank of diesel. When I bought my first gen 5.9 back in the early 90's I used atf about every other tank full .I sold it with almost 400K miles and it NEVER gave me any issues and was still a great engine.

I bought a '03 f350 diesel dually 4x ran horrible, I was laughed at by 2 shops that said scrap it. I found Spanky from Spankies mobile diesel in Boulder City, NV and after a complete exam, and tightening the FICM it ran great, however..still had hard starts, glow plug issues, Spanky said add ATF to tank, after a couple of tanks and 2 qts of atf, no more hard starts, smooth as new. I sware by using ATF.

I ran ATF fluid in my Duramax. A lot more than many would suggest. I’d run up to 15gal in my 26gal tank. Any more and it would start to smoke white. Smoother engine for sure when running and no gelling. I never had an issue so I can’t say it’s a problem. Factory injectors made it to 250k miles.

I ran atf in wll my diesels, from a 95 7.3 to 2000 era 7.3s a 12 valve a 24 valve and a couple 6.0s

I had the similar issue with my 03 and it was the injectors :)

Used to run at in the log trucks I drove. It's fun explaining to a dot why the fuel in your tank is red !

Dude said the glow plug light is on 😂😂😂

I was told to use only dextron and not the ATF that used in the Ford or Dodges…just the stuff that is used in the Chevs!….and oil and diesel fuel do mix…just like oil and gas mix!…and I my buddy has been doing this for 30 years in his trucks and they have hundreds of thousands of miles on his trucks trouble free!..it works!..I would also check the heater grid on the intake…she might have an issue with the power post going into the intake!

This is sweet, nobody ever does this type of stuff. I love it, keep the content coming!

Atf will not harm diesels even long term my dad and uncle ran it in for 40 years in their old tractors and even their regular trucks I even do it in my gassers it helps with keeping injectors lubed have a 04 ram 5.7 hemi with almost 279k miles been doing it ever so often since Oct 2017 when it had only 172k miles and runs perfect I get lot people give me compliments on how it runs even when they have a new ram same engine and mine sounds better than theirs lol

I watch a couple RU-vid channels (Hamiltonville Farms and Diesel Creek) where they have put ATF in their diesel engines to clean up the injection pump and the injectors

aft is fine its hydraulic fluid, with a lot of detergent, yes diesel is an oil burner and it burns oil. there is NOTHING WRONG WITH IT. Diesel tech of 15 years ran it in my trucks sometimes a would pour 5 gallons in the tank at a time

There's also a few guys on RU-vid that run their powerstrokes off ATF only, lookup 7.3 powerstroke ATF as fuel.

Injectors are going the stock body are known for cracking on that year

ATF yes. If i see a stray bottle and know its not gonna be going in car tranny , it goes in diesel tank. Ive put over a gallon in at one time.

What is the best 80hp tune with a dpf delete I can get for a 17 powerstroke? And who would you recommend going through to get parts.

Cory what's the best oil for the powerstroke plz

All those years of CR dodges have injector problems all the way until the late 3g’s early 3g’s are known for injector problems

In fact the RU-vid channel Diesel Creek bought an antique 1950's Loran cable shovel, the guy's that he bought it from mixed old motor oil into the diesel fuel to give the diesel engine some extra top-end lubrication

Should have put it in the filter housing

I was told the fuel has changed from the late 90s till now I got a 7.3 with what I believe to be failing injectors I was really hoping this one or seafoam would get me by till the next full force injectors come in or I might go ith thorghbred diesel injectors

Did you check the turbo seals?

Si it’s safe to do that on a 2002 GMC sierra 2500 HD duramax and works as injectors cleaner?

How big was the turbo installed?

“I drive this everyday”😂

Did it start immediately after you tuned it?

Definitely an injector(s)….. haha nice video man I enjoyed it

Do not use synthetic into the fuel. it may have ruined my Injector pump. Was told it would screw it up. I was using ZF-1 Honda fluid. Still have a couple of cases of that stuff. Type F has grit in it for firmer shifts. Not sure I want that in my fuel system.

Let’s see a pic of that glow plug light I have never seen one

I'd recommend seafoam in the fuel instead, it's cleaned up my injectors before. About 4 oz per gallon is what I used. Considering you could have a lot of sludge buildup in the engine, you may want to run some marvel mystery oil at 20 percent of your oil volume for about 100-300 miles of really hard driving. Change the oil after that and see if it helps at all. It may take several flush outs but I've seen a forum where a cummins owner did this and it cured his rev problem. Other than that it's gotta be computer related

You have a leaking injector, that’s why it hangs up when you rev up.

I fill up semi fuel filters with atf helps prime the system. Y’all need to do some more research on it. It does no harm

all my diesels get 1 quart atf with every other fill up. cant run with dpf but all others are fair game. keeps your injectors clean and increases lubricity thus reducing wear in the entire fuel system. nice vid though.

Oil and fuel do mix. Ol timers will tell you 30W is best 2 stroke mix. Mixes pretty damn good. ATF seems to incapsulate the debris in the fuel system. All I no is guys that tell me they put atf in every other tank have 300k plus miles on injectors and they are quite(healthy). I’ve do it in the Ol 7🌲. Kinda scared to do it in the 6.7. But I do think hot shots LX4 is prob the beat preventive maintenance on those trucks for the CP4🤷🏼

My assumption would be turbo oil leak or injector

I’ve used atf in my diesels for 20 yrs works great

Man put the whole quart in there hell put both of them in there. geez to it up

My 05 did that with bad injectors grid heater light being on means excessive returns no way to fix with additives

retorque fuel lines on rail , there is a update spec

1 qt to a tank of fuel never hurt my Duramax

Different injection system obviously, but I've run almost 100% used ATF in my P-pump 12 valve. Free fuel for me. Runs totally fine can't even tell the difference. I save all the ATF from transmission flushes at work. Drove a whole month for free one time.

ATF is nothing but a detergent but hotshots works really well

Doing it For the thrill of it !

C16 CAT runs good with a Gallon per 100gallons of Diesel. N14 runs the same way.

Atf has powerul cleaners in it.

From what I've heard that is injector problems.

It's definately injectors! The hang up your experiencing is fuel leaking into they cylinder that's is creating the engine to step down the way it is. This is bad for your cylinders because it causes extra heat generates in there. Yes, you do need new injectors. I'm speaking from experience on this one.

If it's on the internet...it must be true 😵‍💫☺️

I think Cummins recommends you don’t do any additives in fuel

what is the code ?

Sounds like she’s got a stiction issue. ATF helps lube cylinders and fuel system better than any other chemicals and snake oils they try to get you to buy. My buddy has a semi he puts ATF in every other fill up and it’s got 875,467 mils on it. 👍🏼

Probably a hanging cable.

Finally I got the notification squad

should have used 2t motor oil

One quart 2 stroke and one quart ATF with every fill up.

I don't know if you don't know what a runaway diesel is Are you were just looking for more clicks.This is not a runaway diesel video.

Not even one quart will you noticed that soon.

Seems like injectors

Injectors

Glow plug light 🤡🤡 lmfao

SEAFOAM

It will run on pure atf if you wanted it wont hurt a thing other than your wallet paying for it

adding ATF will NOT fix your engine.

Are you kidding that, "oil and fuel don't mix?"I don't think either one of you have the qualifications to fix this poor truck. Lol

It won't break older engines also some guys empty the fuel from the carbs in Generators and put atf in the carb for long term storage

Dodge means to avoid
