I know a lot of guys add 2 stroke oil to aid in lubrication for their IP. I had an experince that is relative that I forgot to share. I was running a chain saw on TCW-III 2 stroke oil and the compression ring got coked up solid and it stopped running. If you are going to use 2 stroke, make sure it's the kind for a water cooled engine and not any old crap on the shelf. iirc the tcw-III would work for us but not air cooled engines. My point just being that they are all not the same. I use Marvel Mystery Oil only because it is designed to be burned in auto gas and diesel engines.

I use the Wal-Mart stuff. Its tcw-III and 1.34 a pint. I don't know if its just my ears deceiving me, but it runs quiter than any other additive I've ever used.

2 stroke oils

Hi TC-W3 (from 1988 to now)is low ash oil and is the only one to mix in the fuel tank.

The other one with elevated ash "chaine saw oil"can cause buildup into the IP and the injectors

With such an expensive piece of machinery as the Duramax, why not just buy one of the top brand additives that are specifically made for a diesel?? I'm all for experimenting but, I for one, certainly don't have the money to be second guessing such things on a $45k truck. Call me too skeptical, cautious, or old school but, I can get out on the road, relax and not have to wonder if I'm screwing something up with an unknown that wasn't designed for this thing flowing through the injector pump. Just an opinion.

Right, it is just a backyard trick to put an extra miles on a wornout IP like the transmission oil into the fuel . But who care when you got over 200k on the same IP you can try to make it last for some more time.

And you already now where it gone end ,but not when.

Opps. I didn't notice your sig before. I'll bet you do have some miles on it. I quit buying food for the wife and dog to make the payments on this LLY. First pickup I ever paid $45k for. Geez, I almost could of bought a Corvette Z-06 for what this big guy cost.

Over 325k and lot of fun for 3 years . regular maintenance ,and no i never use 2 stroke oil into my fuel, alway transmission fluid and good additive

People in the diesel world have been doing it for years. It just keeps everything lubed.

And some say never put ATF ours. Seems like a lot of high mileage trucks on here have used good ol' ATF. I know these diesels are more advanced than ever today, but deep down, its still a diesel. Glycol Ether this and organic compound that... just keep her lubed all she'll go a long time. It just seems that the "additive" world it getting very mainstream now.

atf

i heard a buddy of mine talking about putting atf into his cummins to lube it up. he did also say that he has gone through 5 injector pumps for some reason. he has almost 200k miles. could that be because of the atf??? i run howes in every tank. should i run some atf through the system? if so how much?

I'm NOT specialist ,i just follow my 18 weelers experience and at work we had 350-375 units .The master mechanic give us that directive and when i stop driving i bring the experience with me. ATF oil.

So now i apply the same rule for my 6.2 . Never had any issue for 100k in 3 year .not even brake pad ,so the fun continue and the $$$ stay in my pocket;) until the unavoidable happen.

1 cup 8 onces every fill 12-15 gal

DO NOT put ATF in your DMax fuel. ATF added to fuel is "old school" and may have been beneficial to older mechanical injection diesels. It is not a good idea for a High Pressure Common Rail injection system. We've had several lubrication engineers state that contents of ATF (including friction modifiers, anti-foam and dye) would be very bad for the injection pump and injectors. Use a high-quality DIESEL FUEL ADDITIVE in your fuel, not miscellaneous oils, fliuids, solvents and greases!:eek: :rant:

I agree with IdleChatter completely. There are no shortage of chemists and chemical engineers that will tell you the same. GM, Ford, Cummins, and all the rest will tell you the same as well. GM's concern is that you get past that 100k mark and if their engineers and chemists thought ATF or 2 cycle would help they'd state that. We do have a few chemists and engineers on the forum that work in this field as Tom pointed out.

The manual says to add nothing to the fuel and put LOW sulphur diesel only in it. Do you really think there going to say add ATF or 2 cycle in our fuel? No, because its cheap and it's been proven to work. Maybe not so much the ATF in ours but the 2 cycle is fine. All these "additive" companies are raking in the dough charging minimum $5 to buy their product. Just think about how many additives are really out there today compared to 5 or 10 years ago. If these trucks are so technogically advanced then why do we need all of these additives to choose from?
