Diesel fuel lubricity additive

Fred Werring · May 22, 2022

So had a project tractor follow me home. 74 Ford 3000 diesel.

Found the metering valve sticking in the injector (cav) pump. Guess that's not unusual, tractors been sitting 2-3 years.

Read a lot of posts about diesel lubricity. Some say add trans fluid to the fuel, others 2 cycle oil. Still others say get an additive made for the job.

What say you guys? If I use trans fluid or 2 cycle, how much would I put in say 10 gallons?

Thanks

I use 2 cycle oil that says TCW3 on it.
I read a study that said it was better than anything else marketed as a diesel additive.
I use it in my 99 Dodge Cummins and my 2004 Kubota tractor.
The Dodge actually runs quieter with it.
I use one ounce per gallon.

2X 1 oz/gal. 2 stroke oil. It is made to lubricate and burn cleanly.

Unless your local NH dealer is hard to get along with I would ask them. Pumps are very expensive in terms of asking on the net where one formula works well in one instance but may harm another design. Your choice.

Same here. My 851 is much quieter running
it.

We don't use anything and run all ode tractors from the 50's to the late 80's early 90's with only one pump needed replaced and it was pushing 60 years old when I changed it out for a rebuilt last year. Was on an 806 the RD pump. Leaked badly and was having other issues I doubt were from the fuel.

My JD4320 would, when hot, and slowing at the end of the field, idle down to a stall. Sometimes it had to cool for it to restart. If I was in a hurry I could take the cover off the pump and twiddle the linkage in there and get it started. I started adding a gallon of 2cycle oil per tractor tank of diesel. And it totally cured it. Now I just add half a pint per tank, if that. When I fill the 500galfarm tank I add 2 or 3 gallons to it so all the tractors get some. I just use the (cheap?) gallon size 2cycle oil from Walmart.

I second what Richard G stated... 2-cycle oil works great...

Do not use tranny fluid. Some of it has an additive in it to help tranny clutches stick together, its abrasive and can destroy injector tips. You don't need anything if you are using premium #2 diesel. If you are using truck stop or convience store diesel then get yourself a decent lubricity agent such as Howes brand.

I use TCW3 2 stroke oil at 50 to 1 ratio--same as my 2 stroke engines call for

Stanadyne lubricity formula.

The fuel supplier is required to meet lubricity standards so you really should not need anything, but hey, if you sleep better at night...

Frankly I think the "It runs better" comes from the same place as the power boost you get from installing that K&N air filter.

I've got a MF Perkins diesel, and I give her a gloooop of Howe's every tank full. Very economical, and I sleep better. I guess it works, dunno know.
