Adding ATF and/or 2 cycle oil
 

Just wondering if I want to add ATF to my 300SD, what type is recommended? I've read that the new ATF doesn't lubricate as well as the old stuff, so I found some old stuff "Type F" that states its for '78 and older model vehicles...would this be better? And also, is the 2-cycle oil just as good or better for lubrication? I know alot of people say just out diesel fuel additive in, but all the additives say "ULSD compatible" which leads me to believe it was manufactured w/ emissions in mind not necessarily maximum lubrication.....I care more about my injection pump and vehicle performance.....Any input?:confused:

Adding ATF and/or 2 cycle oil is a complete waste of time and money. ULSD does not have any lubrication issues in these cars.

ATF has chemicals in it called "friction modifiers" it does not sound to me like anything i want to put thru my injection pump or injectors.Two stroke oil probably wont hurt anything,but will it help anything? Who knows! If you really think you need to add something why not try something that is made for that purpose like Stanadyne or something similar. My $.02 Don

Stanadyne? I've never heard of that? How do I get it? Is it like an oil of some sort? Thanks, David.

2 Cycle does in fact help lubrication.....http://www.johnfjensen.com/Diesel_fuel_additive_test.pdf

find a station or truck stop that sells ASTM spec B20.. that will do better than any additive you can put in.

From that PDF file

As a result, all oil companies producing ULSD fuel must replace the
lost lubricity with additives. All ULSD fuel purchased at retail fuel stations
SHOULD be adequately treated with additives to replace this lost lubricity.

nvm, i read the rest of that file and diesel is crap. I cant believe B2 improved the lubricity that much

American Diesel has always been crap.

Thanks for the input, for those who are interested found this article....


Recommended diesel fuel additive: Liqui Moly 1052
Some Mercedes-Benz diesel engine engineers recommend to add some two cycle oil to the diesel fuel, in case the engine runs a bit rough due to a batch or so of poor diesel fuel quality in remote areas. In this connection Liqui Moly 1052 is usually mentioned. It reportedly burns clean, better than the diesel fuel itself, and can also be used on diesel engines fitted with particulate filter.

Its as good as done!:D

After reading the article it makes me want to start adding biodiesel (atleast in small percentages). Or some other additive. IS it really something we should worry about? I dont want a bad injection pump on two of my diesels!

Absolutely not. Hype doesn't damage injection pumps.

The entire ULSD myth was made to increase fuel additive revenue.

I agree HYPE does not damage injection pumps, however, it is a proven fact that ULSD does not have the same lubricity qualities that LSD had, and certainly is not what our cars were engineered to operate on. The above article endorses the use of 2 cycle oil in Mercedes diesels by Mercedes engineers...That's all I need to see, I'm at least gonna try it...:)

Then explain to my why, after two years of ULSD, we aren't seeing pumps fall dead?

The answer, because ULSD's lubricity is not a problem.

As you can read in the above article posted by Turbopugsleylx, the processing of ULSD DOES affect the lubricity of the fuel, this cannot be debated. However, it is the distributor's responsibility to add lubrication back into the fuel.....I don't trust that. Several samples of ULSD gathered from random distributors have proved to be very "dry" in terms of lubrication (and YES that is bad for the injection pump, come on lets not deny this). However, the station where you are purchasing your fuel MIGHT be adding the lubrication, who knows? I DON'T TRUST THEM! Are we going to deny the greed of the oil companies next....because you realize this would be an extra cost to them....:P
