diesel fuel lubricity?

[Archive]

WELL - it started here in my beloved California - and I guess it has now spread all thru the other states - lowered sulphur content in diesel fuels, and reduced lubricity for injector pumps and the engine as well...

SO, I know there are a few additives on the market Standyne (sp?), and others - and I personally add about 8 oz. of AT fluid to every tank fillup on my Cummins, as recommended by some backyard chemists/engineers...

SO ~ wonder what the consensus is in THIS group as to the best way to deal with reduced sulphur diesel fuels?

Being an aircraft tech and working on corporate jets I have access to a lot of "extra" Jet A. Jet A has a lower lubricity content than diesel fuel. When filling up the Dodge with Jet A I use a product called Jet A Lubricity Additive made by CTG (Chemical Technologies Group Inc. ) made specifically to raise the lubricity of Jet A from 1200 to 4300 (ASTM B. O. C. L. E. Test). It would be interesting to know what the lubricity content is of the fuel you are purchasing but if you need to raise it and are interested in this product let me know and I will get you their phone number. Not sure of the cost as it is also supplied at work as the diesel powered refueling trucks burn Jet A.

ACTUALLY, I guess I'm MORE interested in the actual effectiveness of these various products, and a more precise description of what they REALLY do for our Cummins engines and injector pumps. I can buy cheap AT fluid as low as . 99 a quart - and that will treat about 3-4 tanks of fuel at my current rate of treatment - so is that anywhere near as effective as products specifically (supposedly!) designed to provide lost lubricity?

For that matter, are my lubricity concerns overblown - perhaps there really is NO threat of increased wear from reduced sulphur diesel fuels?

I'm HOPING to get input from someone who really KNOWS what will work best for our engines at a reasonable cost, and easily obtained - maybe my El Cheepo AT fluid is as good as any, when it comes right down to it? Maybe we don't actually "need" any additives at all?

What I'm NOT looking for, is random, well intended - but meaningless - statements from various users who just pick up some brand off a store shelf because the label looks pretty, and since their Cummins doesn't instantly disintegrate, ASSUME the stuff "must be working good"...

Gary at the National TDR rallies I have attended both Cummins and Bosch have said not to add transmission fluid to the fuel.

Moving on over to General Diesel, let's get it some exposure.

Gary,Gary,Gary! If you think about it,what happens in an auto trans. Friction. The clutches are wearing out a minute amount every time it shifts. I am told that there are additives in trans fluid to help these clutches mate to each other and that it is a friction enhancor. I know a lot of people suggest this but it is an old wives tale delux. Use an aftermarket product that says on the lable that it adds lubricity. No matter what the brand it will be better. the trans fluid helps remove carbon buildup for a short while but after that it's not good. That'sm my 4cents worth. Good Luck.
