Adding Lubricity to Diesel Fuel

Gents:
In the current issue of Successful Farming magazine engine guru , Ray Bohacz , writes that the two keys in order of importance to keeping diesel-injection nozzles in top condition are [1] clean fuel and filters and [2] treating low sulfur diesel fuel with a lubricity agent. I burn about 100 gallons of that each year in my IH 444. Do you men agree with the 2d statement ? If so , what is the name of a quality lubricity agent ?
Obliged.

I recently saw a test that someone had posted over on the Bob is the oil guy site and they had tested all the top brands of diesel additives and even tested 2 cycle oil and stuff like that. Biodiesel won by a considerable amount as an additive over the others when added to regular diesel fuel.

A paragraph from a Caterpillar corp publication:

Fuel Sulfur
Oil contamination can take a number of forms, but none is more rapid in its harmful effect than the
sulfuric acid that can be produced by high sulfur fuels.
In October 1993, low sulfur fuel was mandated in the United States for on-highway vehicles. In the state
of California "ALL" vehicles are required to use low sulfur fuel. Low sulfur fuel was introduced as a
means to meet the engine manufacturers' (EMA's) need for emissions control in these applications.
[u:a23bc74f16]There are few or no negative effects of low sulfur fuels.[/u:a23bc74f16]
Coping with the effects of fuel sulfur is not a simple task. Even though the use of proper lubricants and
correct intervals reduces the degree of corrosive damage, engine wear will increase significantly when
fuels with high sulfur content are used. Not only do these fuels produce acids which chemically attack
the engine, causing corrosive wear, but the oils used to negate the acid effects have a higher ash content
which increases chances of deposit formation.

There is no need for witchcraft and sorcery in your machine's fuel tank.

All the big trucking companies have run tests on this including Dart, one of which I participated in. The results are unanimous, additives are unnecessary and there is no verifiable advantage to using them with the exception of anti-gel's in below zero temps.

Total Bull-feathers.

Never did understand the concept of adding oil to oil, but guess some need that warm cozy notion of those hi-lift 'curb feelers'. :>)

It's just another method of separating you from your cash.

Hello kajun,

Additives are a waste of money. Remember that some injectors have spray nozzle holes as small as .007. Any additives that wont dilute that small will certainly have a tight squeeze through the holes, or pop it wide open.....OUCH!

You will NEVER see the results of a lubricity issue on 100 gallons per year. You will see issues with rust and corrosion. I would worry about protecting for that.

My JD 4320 has a sticky injector pump. It will die when idled down when hot. I know from experience 2cyl oil will add lubrication. I haven't had the JD die since using it. I just add a pint or so to each tank at fill up.

Your problem is probably a failing governor ring, and no amount of lubrication will fix that.

No need for witchcraft and sorcery in the fuel tank or crankcase. Although there are some people that can"t leave well enough alone and believe there are cheap easy gains.
The only exceptions could be IPA to absorb moisture and some diesel anti gelling agents if stuck with summer fuel in the winter.

There are millions of diesel engines around the world running on low sulfur diesel fuel with very little, other than refinery additives put into them. I am no engine garu, but I have been a certified lubrication engineer for 30 years and I don't add anything extra. If your tanks are kept clean and filters changed, you shouldn't have any problems.

Been working for 7 years now. I was about to take the pump off for a rebuild when I tried the 2cyl oil. Worked so good I just kept going.

My JD4020 had the governor ring go bad so I know what it's like.

Gents:

My thanks to all of you . My interest is largely academic . Therefore I scanned the thread and wrote Ray Bohacz as follows:

"Ray:
Here is a question I posted to my favorite website [ farm tractor lovers] . I am kajun in the thread.
The breadth of experience there is pretty large. Until I saw your piece , I never thought about the issue . I am not antsy and my interest here is pretty much academic . On the long haul I have resisted additives of any kind in engines but I would be interested in the science that supports your view and rebuts the views expressed by my “buds” at Yesterday’s Tractors.
Best to you. "

The problem is, there is no way to PROVE one way or the other...

One person with one engine does not proof make. If the engine grenades on you, was it because of the lack of lubricity or was it just a defective engine? Or was it something else totally unrelated?

As Jason S. said, Biodiesel is tops, even at 2 %, many are better than Power Service.

Here is a link to test results

Anecdotal evidence doesn't prove a thing. Just because you add X amount of X to your diesel fuel and never have any problems doesn't mean that X is responsible for your good fortune. I have owned OTR trucks for 18 yrs and don't add any additives to my fuel except in temps below 10 deg I use Power Service. The only trouble I have ever had with freezing up was when I had no Power Service and used Howes. I'll never use that stuff again. YMMV

the person that made that politically correct statement for cat needs to open a few metal fuel tanks and observe the rust that you use to not see if it was wet with diesel

I have noticed that if I put a shot of [b:1f17db843c]Wild Turkey[/b:1f17db843c] in my tractor tank, and then put three more shots in my belly, my tractor seems to run much smoother than without the above additives.
