Question 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?

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.

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.

I'm under the impression that ATF is added to fuel, occassionally, in order to clean the fuel system. ATF is not added specifically for lubrication purposes. I was told to do this by a couple of indy mechanics in the area. That said, I haven't burned anything but diesel fuel.

ATF is an old mechanics tale that cokes injectors.

Don't worry. I sure like the reduced MPG and slower burn rate too.

No need. My pump has been running perfect on ULSD from day 1.

Nobody loves capitalism more than me sir. This post is about FUEL ADDITIVES, if you want to talk politics we should move to the "General Discussion" forum.

I add 12oz of Marvels Mystery Oil to every tank. Engine runs noticeably smoother.
