Engine/Transmission (1994 - 1998) 2 cycle oil in fuel

[TEasley]

I searched this forum for fuel additives, and came up with several people who use 2 cycle oil as a lubricant in diesel fuel. I never thought of it. Would like to hear more. Is it too good to be true?



Thanks, Tom.

I wouldn't. Might be to much ash and wrong type of additives in it. If you want an additive for you fuel use Diesel Power, Howes, Shafers(sp)2000 diesel treat or for the best, use Stanadyne. Ignore most everything else. Just my 02 cents worth.

2 cycle does work for lub in diesel fuel and works good I have been having all my cust and myself using it for the last 10 yrs.

 

[Kiohio]

Would it matter if it is regular 2-stroke or would outboard motor 2-stroke work too?

[Dieseldemon]

Any 2 stroke will work Wal-Mart has it for 8. 14 per gal.

You need to use a TCW-3 with low ash.

Here is a link with alot of info on this topic. First Time w/2stroke Oil - Dodge Cummins Diesel Forum

Why use it, or any other additive for that matter? The ULSD scare? Other than gelling of warm climate fuel going into a cold climate I've never used any. Still running the original injectors and injector pump. I'll save my TCW-3 for my 150 Johnson. (that's an outboard engine, by the way)

Here is a list of the best oils to use. View attachment 64902

It's not needed as much in the 12 Valves but in the 24 Valves I know alot of people who run it to be safe. Here are some stats on the ULSD with and without 2-stroke oil, this should clear things up a bit. 2 Cycle Oil Research

I am going to go back to the early 90s in Calif when the sulfur was first reduced the state of Calif paid for a lot of the early inj pumps that the low sulfur diesel caused to leak because of the o/r shrinkage also I had a lot of cust complain of low power at the time we were using ATF for lube in the fuel it picked up the lost power and ran smoother Dodge was calling it heat soak. For now I will stick with 2 cycle oil low ash or high ash in my 98 12v

2 Cycle Oil Research

I didn't read past the second paragraph. Anyone who thinks that sulphur is a lubicant has zero credibility with me. Dump whatever you want in your tank. I'm thinking sulpher from a garden center is cheaper than 2 cycle oil, so if you dissolve about a cup of it in a quart of ATF you should really see some high performance results.

I don't run it in either of my trucks because I run B20 Biodiesel and it has plenty of lubricity in it. Despite what you may think though sulfur does add lubricity to diesel fuel. Just read thishttp://www.expressmart.com/ulsdiesel.pdf But there is no need to bash my opinion because you disagree with it. If putting 2-cycle oil in is wrong then why did Cummins make the Centinel. Cummins.com > Investors And Media > Press Releases And why do so many people do it now. But you don't have to put it in yours if you don't want to. Just leave this thread to the guys who are interested in putting it in.

I'm not bashing those who use 2 cycle oil, I just don't see any benefit in it. The only harm I see is to the wallet. I am bashing anyone who proposes that sulphur is a lubricant. Try this. Pour some oil in your palm. Rub it between your fingers. Nice and smooth isn't it. That is lubricant. Now add some sulphur to it. Wait till it dissolves. Rub it between your fingers. Feel that heat? That is not lubricant. But don't believe me. Read about sulphur and see if you can find any reference to it being anything but an acid. Here is a start.

Sulphur

I am not saying that sulfur is a lubricant by itself because it is not. It's just that the process they use to reduce sulfur also reduces the lubricating properties of the fuel. If you would read the whole article on the 2-cycle oil it will show you he is not saying that sulfur is a lubricant by itself but only when combined with other lubricants does it serve as an extreme pressure lubricant to raise the molecular barrier break down point. Many people have claimed increases in fuel mileage running 2-cycle plus knowing your fuel system is well lubricated is worth it to me and alot of other Cummins owners.

 

[GAmes]

Listen to yourself, sulphur is not a lubricant, but if you mix it with something else it is. I give up.



I have found that by adding a quart of diesel fuel to 20 gallons of diesel fuel I can go farther.

 

[BigDsCummins]

You obviously do not understand what I am trying to say, but despite that, there are alot of gear oils and other types of oils that are formulated with additives that contain active sulfur. There are many different types of chemical compounds of sulfur, for example, sulfur containing diols are reacted with hydroxy boron compounds resulting in the formation of balanced compounds which are useful as additives for lubricating oil compositions. Just read this and it will help you understand what I am saying. Oil analysis and lubrication learning cennter and this too, it is from Schaeffers site, a huge diesel manufacturer. Pay close attention to the last paragraph. Schaeffer Premium Diesel | Ultra Low Sulfur Diesel

 

[BigDsCummins]

But even so, none of this conversation about sulfur matters because everyone knows that the process that is used to reduce sulfur also reduces the lubricity of the fuel and with the lubricity of the fuel being lower common sense tells us that fuel mileage and wear and tear on your fuel system is compromised. Therefore that is why some people use 2-cycle or any kind of fuel additive for that matter.

Hey big d try explaining it to the wall you may have better results. Its hard to get people who have closed minds and are only willing to pick and chose words out of a paragraph to make their point.



For me. I know that when my truck was made ULSD was not on the market, therefore my fuel system componets were not designed to operate with it. I know that sulpher doesnt lubricate, but the process to remove it also affects the lubricity of the fuel. I also know that my 1200. 00 IP needs lubricated fuel.



I don't know for sure what it best to do to increase the lubricity of the fuel. But then again that's why I am a member here to hear other peoples ideas and thoughs, and suggestions. But to argue to some guy who obviously doesn't understand even after you CLEARLY explained it, is rediculous.



Now Games you can just agree to disagree, but you should read and understand the information before you coment on it. If you don't understand it (which is obvious) then ask I am sure someone here will help explain it to you!!

I understand it just fine. The process to remove sulphur also strips out some lubrication properties. To compensate for that refineries add back another lube additive. If you want to add oil designed for a 2 cycle engine, be my guest. Just don't expect any miracles when it comes to extra mileage. I have probably burned more ULSD this year than you will burn in 5 years. Sulphur is a corrosive, plain and simple. Added to liquid it becomes an acid. When burned it produces a toxic gas, that is why the new fuel standards are in place. If you don't understand that maybe someone will explain it to you.
