Diesel additives?

[JDTank]

We started selling Amsoil diesel fuel additive at my work now. I am thinking about using it since I can get it at our cost. This is the stuff we carry and I can get it for about $3 a bottle.

Amsoil Diesel Concentrate Performance Fuel Additive

I am contemplating using it in my X740, but I am just wondering if it would make any real difference at all? Basically, just not sure if it is pointless to use or not.

Looking for any knowledge from those who know about additives!

Well the label states " Designed for use in heavy-duty diesel engines." does that include a x740 lawn mower?

I know I know. These little Yanmars are industrial grade diesel engines. I just figured since I can get the additive for next to nothing, maybe it is worth it to just keep the injectors cleaned and lubricated if anything?

You will have to try it to answer that question.

We use the WM 2 cycle TCWC oil as our diesel additive. On the 1983 JD 60 HP diesel I can see/hear no difference in the engine but the drops of water in the fuel filter will leave very fast. Now in the 1976 MF 60 HP the injector pump rattle does decrease to my ears.

What does your manual say about additives? I know what mine say's.

I am of the opinion that ALL injector pumps will last longer with some additional lubricant in the fuel.
Especially the older ones which tend to leak and give troubles related to the newer fuels (after ~ 2006-2009)
with lower sulphur content. Lots of truck driver and equipment operators buy these additives by the case all year long.

Some injector pump mechanics say to use ATF fluid. Others use some form of 2-cycle oil.
Google it...
Most (not all) injector pumps are lubricated ONLY by the fuel, and the new fuel is too clean.

I use Amsoil Diesel concentrate in all my diesels. My John Deere 3720, which has a Yanmar engine and my F250 which has a 6.7L diesel, etc. I am religious about it since the ultra low sulfur standards came out. I have not had any fuel related issues with any of my equipment.

The manual for my x748, and my 4720 say the John Deere additive is recommended for fuel of low or "unknown" lubricity. I think you could make a pretty good case that most fuels fall into the "unknown" catagory. I've always used the JD additive, but I have considered switching to Optilube. I would not be scared of any Amzoil product either.

I just looked in my manual tonight, and I can confirm you are correct. It actually does suggest using an additive.

Ever since Ultra Low Sulfur Fuel came into play, the quality of diesel isn't the greatest. The fuel itself has never been cleaner, but it also has never lacked so many properties it used to have, like lubrication. Sulfur used to do good things for your fuel injectors. However, I do know that it is EXTREMELY harmful to the environment.

I know Amsoil makes a top quality product, and they don't take their stuff lightly. I think I will start to run this stuff on my next tank. I plan to keep this tractor for a lot of years, so I am looking for the maximum life out of my machine.

I disagree with the "unknown" part, from all I have read. I KNOW the current diesel does not lubricate like it used to.
The stupid part to me is that the environmental folks done this to help, but it is now causing expensive injector pump failures.
So millions are now riding down the interstate with oil of some sort added to the tank. Is that good for the environment?

I use "Power Service" Diesel Fuel supplement in ever tank. 1.6 oz to each 5 gallon can. It has "SlickDiesel" lubricant and an anti-gel additive for the wintertime. About $11 to treat 100 gallons of fuel.
